Abstract
Background
The growing interest in mineral resources of the deep sea, such as seafloor massive sulphide deposits, has led to an increasing number of exploration licences issued by the International Seabed Authority. In the Indian Ocean, four licence areas exist, resulting in an increasing number of new hydrothermal vent fields and the discovery of new species. Most studies focus on active venting areas including their ecology, but the non-vent megafauna of the Central Indian Ridge and South East Indian Ridge remains poorly known.
In the framework of the Indian Ocean Exploration project in the German license area for seafloor massive sulphides, baseline imagery and sampling surveys were conducted yearly during research expeditions from 2013 to 2018, using video sledges and Remotely Operated Vehicles.
New information
This is the first report of an imagery collection of megafauna from the southern Central Indian- and South East Indian Ridge, reporting the taxonomic richness and their distribution. A total of 218 taxa were recorded and identified, based on imagery, with additional morphological and molecular confirmed identifications of 20 taxa from 89 sampled specimens. The compiled fauna catalogue is a synthesis of megafauna occurrences aiming at a consistent morphological identification of taxa and showing their regional distribution. The imagery data were collected during multiple research cruises in different exploration clusters of the German licence area, located 500 km north of the Rodriguez Triple Junction along the Central Indian Ridge and 500 km southeast of it along the Southeast Indian Ridge.

Introduction
The Central Indian Ridge (CIR) and South East Indian Ridge (SEIR) are part of a global oceanic ridge system with high magmatic activity, which creates new seafloor, volcanoes and hydrothermal vent fields (Kelley 2001, Wang et al. 2012). High-temperature hydrothermal activity is often focused along topographically shallow portions of a single ridge segment, where a large magma reservoir causes crustal buoyancy (Ballard et al. 1981, Francheteau and Ballard 1983, Herzig and Hannington 1995). The hydrothermal activity accumulates polymetallic sulphides on the seafloor that may form seafloor massive sulphide (SMS) deposits with high content of iron, copper, zinc and rare earth metals in economically valuable amounts (Van Dover 2011, Miller et al. 2018, Van Dover 2019). The highly abundant and mostly symbiotic fauna that exist in hydrothermally active deposits in the Indian Ocean benefit from bacterial primary production and consist mainly of shrimp swarms, bivalve mussel beds and dense anemone fields (Hashimoto et al. 2001).
Along the spreading axes of the Indian Ocean, exploration licences for SMS deposits as potential mineral resources are issued by the International Seabed Authority (ISA; www.isa.org.jm). The ISA manages the areas beyond national jurisdiction (Levin et al. 2016) and regulates the human activities in the context of mineral resource exploration and exploitation that may take place in the near future (Ramirez-Llodra et al. 2011). This includes the protection of the marine environment from anthropogenic impacts, such as mineral extraction and mining technology testing (Rogers et al. 2012, Levin et al. 2016, Miller et al. 2018). To date, seven exploration licences for SMS deposits have been issued by the ISA; three on the Mid-Atlantic Ridge (MAR) and four in the Indian Ocean (www.isa.org.jm).
Possible future mining events at inactive hydrothermal vents will physically remove hard substrates and the local fauna, thereby flattening the vertical topography and permanently reducing habitat heterogeneity (Van Dover 2014, Levin et al. 2016, Van Dover et al. 2020). Since inactive vents may act as stepping stones for population recolonisation, removal of substrate during SMS mineral extraction may halt recolonisation (Van Dover 2014, Van Dover et al. 2020).
Such mining-related activities and disturbances will likely affect the hydrothermal vent fields and their surrounding areas, making taxonomic and ecological baseline studies essential for describing undisturbed environmental conditions and assessing potential mining impacts (Copley et al. 2016). Imagery-based studies are an accurate and cost-effective tool (Sen et al. 2014, Van Dover 2014), as they are able to detect environmental changes or serious harm (Van Dover 2019) to the ecosystem.
Deep-sea megafauna are important components of biodiversity and play significant roles in ecosystem functioning, as pointed out for megafauna occurring in nodule areas (Smith et al. 2008, Vanreusel et al. 2016). These ecosystem functions include utilisation rates of surface derived detritus, dietary composition or the locomotion mode. Megafauna are likely subject to drastic changes due to mining activities and are expected to recover slowly related with slow rates of growth and recruitment (Ramirez-Llodra et al. 2011, Amon et al. 2016, Gollner et al. 2017). Many megafauna taxa are considered as indicators of physical disturbance responding to disturbance events with changes in densities, dominating taxa or the community composition (Bluhm and Gebruk 1999, Amon et al. 2017).
Environmental research has been conducted in the framework of the German Indian Ocean Exploration (INDEX) project and includes biological benthic baseline studies in accordance with ISA environmental guidelines (www.isa.org.jm (ISBA/25/LTC/6/Rev.1); Ardron et al. 2011, Miller et al. 2018). The German licence area (GLA) in the Indian Ocean is located along the southern CIR and northern SEIR (Fig. 1). The INDEX project is conducted by the Federal Institute for Geoscience and Natural Resources (BGR, www.bgr.bund.de) and aims to find massive sulphide deposits in economically valuable amounts for potential exploitation. The GLA covers 100 exploration blocks, each 10 x 10 km in size, with a total area of 10,000 km2 of deep-sea floor. A vast number of photographs and video material has been collected during annual expeditions from 2013 to 2018 and has been used to create annual fauna catalogues of specific regions or clusters within the licence area.

This study combined the existing imagery of the taxa observed within the GLA to create a taxonomic expert-revised faunal catalogue with consistent identifications for the six years of exploration. The goal of the image analysis was to assess the species richness of benthic megafauna within the GLA, covering active and inactive hydrothermal vent fields and their surrounding non-vent areas, namely the abyssal deep-sea areas along the spreading axis of the southern CIR, the Rodriguez Triple Junction (RTJ) and the northern SEIR.
Materials and methods
INDEX expeditions and imagery acquisition
Six expeditions in consecutive years from 2013 to 2018 were used for this imagery study and covered a cumulative bottom track distance of 220,983 m. A total of 122,918 photographs and 367 hours 10 minutes of video imagery were collected. All photographs were reviewed and faunal occurrences annotated and extracted; video imagery was only used when additional imagery was necessary to clarify the imagery-based identification. The study area has a bathymetrical range of 2,280 – 3,770 m and spanned a geographical range from the MESO areas (after RV Meteor and RV Sonne; Muench et al. 1999) outside the German licence area on the southern CIR at 23°23'S, 69°14'E, to Cluster 12 on the northern SEIR at 27°42'S, 73°44'E (Fig. 1). The MESO area was studied during the pre-exploration period and later excluded before signing the exploration licence in 2015.
All imagery transects were conducted using three different video sledges and three Remotely Operated Vehicles (ROVs). The towed video platforms were the Multifunctional Tool (MFT) and the STROMER (STR), both belonging to the BGR and the video sledge (VS) of the Royal Netherlands Institute for Sea Research (NIOZ). The ROVs were the Kiel 6000 from the GEOMAR, the Remotely Operated Platform for Ocean Science (ROPOS) of the Canadian Scientific Submersible Facility (CSSF) and the ROV Victor 6000 of the IFREMER. Table 1 lists gear details and total photographs and video imagery collected. Table 2 lists specifications of the sampling gear, such as the camera equipment used and the imagery resolution.

Megafaunal imagery analysis
All taxa visible in photographs and video were annotated, cut out, and the individuals identified to the lowest taxonomic level possible. Photographic analysis was carried out using Adobe Photoshop Lightroom 5.7 (©2019 Adobe Systems Software Ireland Ltd.; www.adobe.com). Photographs were imported and automatically white-balanced and tone-corrected; year and station were added to the metadata for standardisation purposes and use in an imagery database.
Each photograph was magnified until identification was impossible due to pixelation and each section searched for both sessile and motile animals (Schoening et al. 2012). For each individual organism, a copy was created and the section containing the animal cut out. Folders were created in Lightroom in a taxonomic hierarchy following the classification in the World Register of Marine Species (WoRMS Editorial Board 2021). The morphotype or species and the abundance in the photographs were written into the metadata and resulted in up to 100 cut-outs from different photographs of individual taxa. The initial identification was based on taxonomic and imagery databases, photograph and video imagery galleries and scientific publications. In addition, selected images of all taxa were validated by the respective taxonomic experts of the team to check for consistency of the initial identification (Suppl. material 1).
The metadata of the processed photographs were exported and included taxon, abundance, expedition, year, station, GPS coordinates and technical information about the camera using the plug-in ListView (www.lightroomsolutions.com) for Adobe Photoshop Lightroom; the fauna catalogue shows selected images of each taxon.
The video imagery analysis was carried out with the video processing programme Magix Video deluxe 2014 Premium (©2003-2020 MAGIX Software GmbH; www.magix.com) primarily using video tracks from the ROVs; MFT video imagery was only processed in addition to photographs, if supporting the identification.
Both frame grabs from the video and short video films were exported and the frame grabs were used for the extension of the fauna catalogue. Short video films were cut out and added if the movement was characteristic for the animal and, therefore, helpful for identification (pers. comm. H. Singh Woods Hole Oceanographic Institute, Massachusetts, USA). The identification process was carried out in the same way as for the photographs. Detailed metadata information, such as sample locations, gear, depth, sampled specimens and camera information are listed in Suppl. material 1.
Sample collection
A total of 89 specimens were collected throughout the expeditions using ROVs, mainly within active hydrothermal vent fields. Megafaunal specimens were quickly transferred to chilled seawater and photographed, and tissue subsamples or the entire animal were preserved in 96% ethanol for molecular analysis. Onboard photographs of the sampled specimens were included in this manuscript if they showed characteristic details helpful for taxonomic identification. In the laboratory, the specimens were assigned to the lowest taxonomic level possible using a sequenced segment of approximately 650 bp of the cytochrome oxidase subunit I (COI) gene. Molecular samples were used to verify identifications based on images.
Applied open taxonomic nomenclature and technical notes
Note: Scaling of photographs was, in most cases, not possible due to missing lasers or lasers visible on a different focal plane. Only size estimates, based on samples or in relation to known sizes of taxa, are given. The identification of taxa, based only on imagery, is very difficult and many of the taxa presented herein might be new species. Llife traces and the phylum Porifera, with the exception of a single trace listed as poriferan taxon, Paleodictyonnodosum, are excluded from this catalogue. The phylum Porifera was excluded from this megafauna catalogue because of the high diversity of this group and the difficulties to discriminate these morphologically very similar taxa from one another, based on imagery alone without physical samples within the INDEX area.
Some putative taxa presented have an asterisk followed by an additional taxon name in squared brackets as, for example, “Genus species *[Genus species sp. inc.]”. This means that the image shown in the catalogue has the “Genus species” identification level, even though there do exist certain images in Suppl. material 1, where the species level identification remains uncertain. These images are indicated by “*[Genus species sp. inc.]”, but are assumed to belong to this higher ranked identification level. This was applied where only part, but not all, of the imagery samples could confirm a taxonomic group, based on morphological or molecular results (or both). It has been suggested, in these cases, to move the identification rank up to the level where all images could be reliably identified (Horton et al. 2021). Since this meant a loss of accuracy of the generated dataset and omission of valid identifications made, we decided to keep the higher level of accuracy and introduced and defined the use of the asterisk and squared brackets.
Several abbreviations were used in this fauna catalogue following the recommendations for standardisation of imagery-based annotations by Horton et al. (2021). The taxonomic ranks ˈcl.ˈ (“class”), ˈord.ˈ (“order”), ˈfam.ˈ (“family”), ˈgen.ˈ (“genus”) and ˈsp.ˈ (species) indicate the taxonomic rank and are always combined with the open nomenclature (ON) signs ˈindet.ˈ, ˈinc.ˈ or a unique code applied for this taxon (taxon rank (unique code)). Several morphotypes have a unique code in brackets (DZMB_2021_00xx), that has been assigned to all morphotypes where more than one taxon could be distinguished, but not identified to species level, based on the available imagery. These ON signs are defined according to Horton et al. (2021) as follows:
The ˈspp.ˈ (“species (plural)”) was used when there is more than one species present within an identified group of organisms, but could not be further distinguished, based on the imagery.
The ˈindet.ˈ (“indeterminabilis”) means that no further identification was possible because diagnostic characteristics were not visible. Missing diagnostic characteristics are often related to blurry imagery, low resolution, orientation of the organism and missing physical samples.
The ˈinc.ˈ (“incerta”) means that diagnostic characteristics and (or) physical sample were present, but the identification is still uncertain and needs further comparable material for validation.
Table 3 contains all taxa included in this catalogue.
Table 3.
List of all taxa in this fauna catalogue including phylum and the scientific name authority for the taxon. The asterisk and species names in squared brackets means that a taxon has been identified in several images, but a given identification level could not be supported in all images because not every single observation could be supported by morphological or molecular methods or contradictory results of different methods exist. Some putative taxa presented have an asterisk followed by an additional taxon name in squared brackets, as, for example, “Genus species *[Genus species sp. inc.]”, meaning that the image shown in the catalogue has the “Genus species” identification level, with further images, where the species level identification remains uncertain, indicated by “*[Genus species sp. inc.]”. The taxonomic ranks ˈcl.ˈ (“class”), ˈord.ˈ (“order”), ˈfam.ˈ (“family”), ˈgen.ˈ (“genus”) and ˈsp.ˈ (species) indicate the taxonomic rank and are always combined with the open nomenclature (ON) signs ˈindet.ˈ, ˈinc.ˈ according to Horton et al. (2021) or a unique code applied for this taxon (taxon rank (unique code)).

Notes
Remarks: The animal seen in Fig. 164 appears to be an irregular sea urchin, based on the overall shape and darker radial regions possibly representing ambulacra. It could belong to a number of different groups, including holasteroids, spatangoids and cassiduloids. The blurred nature of the image renders a more refined identification impossible.

Notes
Remarks: The echinoid seen in Fig. 166 clearly is a member of the subfamily Echinothuriinae, based on the presence of primary spines with their characteristic terminal hoofs. Identification to genus and species level is difficult in echinothurioids, specifically when based on images, since many forms are largely differentiated by details of their plate arrangement and pedicellarial morphology. In the present case, however, some information on the pedicellariae can be gained from the images. The specimen possesses very large tridentate pedicellariae with rounded blades which broaden towards the tip from a narrow base, a feature only known from species of the genus Hapalosoma (see Mortensen 1935, Anderson 2013). Four species of this genus are known (Anderson 2013), but none of them occurring in the Indian Ocean (having been reported from the New Zealand region, Malay Archipelago and Sagami Sea). That fact, combined with the divergent colouration of the observed specimen, suggests that it might belong to a new, yet undescribed species of Hapalosoma.

Less detail can be recognszed in an individual seen in images R1915_00209 and R1915_00213, but the high similarity to the specimen in Fig. 166 suggests that this might be a second representative of this putative new species.

Notes
Remarks: The presence of relatively few, long and slender spines with upturned distal ends characterise the observed echinoids as saleniids. This is further supported by the excentric position of the periproct and large apical disc seen in Fig. 167. Of extant saleniids, three genera are known, two of these (Salenia and Bathysalenia) are characterised by distinctly banded spines (with the exception of Saleniaunicolor Mortensen 1934 from the Sagami Sea and the Celebes Sea) and can be excluded. Saleniaunicolor is reported to have greenish-white primary spines and a greyish-purple test (Mortensen 1935), unlike the observed animals which have white spines and a white to light purple test. The observed specimens are thus assigned to the genus Salenocidaris. Amongst Salenocidaris, the most likely candidate seems to be S.hastigera (Agassiz 1879), which fits in terms of colouration and has been reported from the Malay Archipelago and the Indian Ocean (Mortensen 1935). The latter were assigned to a separate variety (now considered a subspecies) S.hastigeraacuminata, based on the long and pointed ambulacral spines (Mortensen 1934) – a feature which cannot be evaluated in the in-situ images available. A second possible candidate species is Salenocidarisincrassata Mortensen, 1934 described from the Celebes Sea. It is characterised by non-contiguous areoles of the primary interambulacral tubercles and distally thickened secondary spines – again features not visible in the available imagery. All other Salenocidaris species are either occurring in different oceans or are characterised by violet to dark purple tests and can, therefore, easily be excluded.

Discussion
Despite the majority of the 218 taxa identified solely on imagery and physical samples existing for a considerably lower number, this is the first image atlas of the deep-sea benthic megafauna for the GLA, covering the southern CIR and northern SEIR in the Indian Ocean. Specifically, the atlas consists of the first collection of imaged taxon occurrences within active hydrothermal vents and their periphery, inactive vent sites and the non-vent areas in a region potentially exposed to mining and, thus, presents valuable biological baseline information.
Amongst the 218 taxa, the phylum Cnidaria are represented by the most taxa (77), followed by the phyla Echinodermata (48), Chordata (30), Arthropoda (22), Mollusca (17), Annelida (9) and Bryozoa (4). The phyla Hemichordata, Nemertea, Platyhelminthes and Porifera are each represented by one taxon. However, the latter phylum was excluded from this catalogue as noted in the Methods section, but has a considerably higher number of taxa (Table 5).
Table 5.
Number of taxa/species in each phylum at the Central Indian Ridge (CIR), the South East Indian Ridge (SEIR) and the Rodriguez Triple Junction (RTJ). Numbers include active vent taxa, inactive vent taxa and non-vent taxa. Note, that the phylum Porifera was excluded from this catalogue, with the exception of a single species.

| Porifera | 1 | 1 | - | 1 |
| Foraminifera | 5 | 4 | 2 | 7 |
| Total | 122 | 152 | 86 | 218 |
In the Kingdom Chromista, protists, belonging to phylum Foraminifera, contributed seven taxa that could be distinguished, based on imagery. Some are tentatively identified to genus level, but these identifications cannot be confirmed from photographs alone. The identification of xenophyophores from photographs is particularly problematic. Nevertheless, these protistan taxa were consistently identified in all years and by all sampling gear.
Active hydrothermal vent fields
A total of 93 megafaunal taxa were recognised from the active hydrothermal vents, based on imagery (Table 6). This number includes non-vent species occurring in close proximity to active hydrothermal active vent fields without directly depending on-, or being influenced by, fluid discharge. Of all visually observed taxa, 18 could be confirmed taxonomically or based on molecular methods via sampling in Edmond (CIR, 7 taxa), Kairei (RTJ, 15 taxa), vent site 1 (CIR, 8 taxa), vent site 4 (RTJ, 2 taxa), vent site 5 (SEIR, 2 taxa), vent site 6 (SEIR, 2 taxa) and Pelagia (SEIR, 9 taxa) (vent field data and names not published). A single Freyella gen. inc. was observed within vent site 4, but this taxon is generally considered a non-vent species.

Of the total of 93 taxa found within and in close proximity to hydrothermal vents, 29 identified megafaunal taxa were considered endemic at active vent fields. This number is comparable to the total of 46 megafaunal taxa identified from imagery or physical sampling at Dodo, Solitaire, Edmond and Kairei vent fields, stretching along the CIR and at Longqi and Tiancheng along the South West Indian Ridge (SWIR) (Watanabe and Beedessee 2015, Sun et al. 2020). In particular, four species were identified at the Dodo vent field; 18 taxa were initially identified within Solitaire (Nakamura et al. 2012) and subsequent physical sampling and taxonomic work revealed 22 taxa (Watanabe and Beedessee 2015). At Longqi, 21 were initially identified through observation and sampling (Copley et al. 2016) and 32 taxa have since been recognised (Zhou et al. 2018). A total of 23 species and morphotypes were recognised at Tiancheng vent field, including the active venting area and the periphery of the vent field (Sun et al. 2020). At Kairei vent field, 26 taxa were reported when the vent field was discovered (Hashimoto et al. 2001), with a subsequent increase to 34 known taxa (Watanabe and Beedessee 2015). For the Edmond vent field, Watanabe and Beedessee (2015) described six taxa.
Inactive hydrothermal vent field
We recognised a total of 69 taxa at inactive vent fields and inactive parts of active vent fields (Table 7), of which 37 are shared species with non-vent areas and 30 with active vent fields. Twenty two taxa were found exclusively within or close to inactive vent fields, 15 of these within inactive sites.

Presence of each taxon indicated as low ('+'), medium ('++') or high ('+++') density. Low density = 1 specimen, medium = 2-9 specimens and high ≥ 10 specimens. Taxa found exclusively within or in close proximity to inactive hydrothermal vent fields are highlighted in bold, taxa observed only within inactive vent fields are additionally indicated by a plus.

The few studies focusing on megafauna at inactive vent fields found that most taxa are known from other hard substrates and were not endemic or strictly dependent on inactive hydrothermal areas (Boschen et al. 2013, Boschen et al. 2016). Nevertheless, the faunal composition and abundance of these non-vent taxa were different within inactive areas compared to those observed in non-vent areas on hard substrates.
Some species were found exclusively at inactive vents, including two limpet species from the East Pacific Rise (McLean 1990) and one polynoid polychaeta from the Galapagos Spreading Center (Pettibone 1989). At the SWIR, within the Longqi hydrothermal vent field, an unknown ampharetid polychaete was sampled that Zhou et al. (2018) suggested to be adapted to inactive sites.
In the Pacific Ocean aggregations of non-vent fauna, such as solitary tunicates, brisingid sea stars, crinoids, sponges, anemones and brachiopods are found on inactive hydrothermal sulphides at Gorda Ridge (Van Dover et al. 1990). Observations from inactive sites close to Rumble II West Seamount off New Zealand revealed aggregations of comatulid crinoids, actiniarian anemones, sponges, ascidians, brachiopods and several coral species (Boschen et al. 2016). Similar suspension-feeding communities in comparably high abundance are reported from inactive sulphides at the Manus Basin (Galkin 1997, Sen et al. 2014) and Brothers Seamount (Boschen et al. 2015).
On inactive chimney complexes at Longqi, Zhou et al. (2018) reported occasional occurrences of Munidopsis-type galatheids; these inactive chimneys are relatively close to active vent sites, which might influence their faunal composition. Munidopsis species are also present within inactive sites in the INDEX area that lacks any recent hydrothermal activity.
Non-vent area
A total of 134 megafauna taxa were identified in the non-vent areas (Table 8), of which many were observed within inactive vents and in the periphery of active vents. Many of these shared taxa represent mobile individuals, especially of the phylum Chordata.

Information on the benthic deep-sea megafauna of the Indian Ocean from both samples and imagery are rather scarce (Ingole and Koslow 2005, Sautya et al. 2011) and often focuses on the shelf (Hunter et al. 2011). Sautya et al. (2011) identified 58 megafaunal taxa using video transects and TV-grab samples from the Andaman Sea, a back-arc basin in the northern part of the Indian Ocean, although the highest diversity and density was observed on the flanks or summit of seamounts and only seven were found in the Andaman Basin on fine sediments (2,876 –2,917 m).
These seven taxa were observed at similar depths to those recorded here from the CIR and SEIR area, all on soft substrates (Sautya et al. 2011). The imagery samples from the seamounts, representing hard substrates, were taken at a maximum depth of 1,424 m (Sautya et al. 2011), much shallower and more influenced by surface primary production compared to the deeper and oligotrophic study area (Harms et al. 2019).
Ingole and Koslow (2005) recognised 38 megafaunal taxa from video transects and sampling in the Central Ocean Basin. Other studies in the Indian Ocean focused on macrofauna (Ingole 2003) and responses of macrofauna to disturbance (Ingole et al. 2001, Jones et al. 2017).
Megafauna in the German licence area
The GLA covers three regions; the southern CIR, the RTJ and the northern SEIR, a distance spanning 1000 km from the northern to the southern border. Several taxa are widespread throughout the INDEX area and others have restricted distribution patterns (Tables 6, 7, 8). For the active vent fields, 19 species occur on the CIR, SEIR and RTJ, including the shrimp Rimicariskairei, the bristle worm Archinomejasoni, the fish Pachycaraangeloi and the mussel Bathymodiolusseptemdierum (Table 6). Fifty taxa were found only in one region, including the bristle worm Branchipolynoe gen. inc. on the CIR, the sea spider Pantopoda ord. inc. on the SEIR and the ribbon worm Thermanemertes gen. inc. at the RTJ (Table 6). The remaining 26 taxa were observed in two of the three regions, ten of them on the CIR and SEIR, but not within the RTJ in between these two regions, thereby probably reflecting the sampling effort.
The widespread distribution throughout the INDEX area of many typical active vent field taxa found in this study confirms the Indian Ocean as a standalone biogeographic province (Van Dover et al. 2001, Zhou et al. 2018, Sun et al. 2020). The majority of spatially-restricted taxa were either smaller taxa, as reported for polychaetes from Longqi (Copley et al. 2016, Zhou et al. 2018) or were occasional vent field residents also found in more distant non-vent areas (compare Table 6 and Table 8 for shared taxa). These taxa probably contribute to the small-scale differences described for Indian Ocean vent fields (Copley et al. 2016, Zhou et al. 2018, Sun et al. 2020) and can also be confirmed for the active vent fields within the INDEX area.
At inactive hydrothermal vent fields, the majority of taxa were shared with active vent fields and non-vent areas and only 22 of the 69 taxa were observed only within - or close to - inactive areas. Fifteen taxa were observed exclusively within inactive areas on sulphides. Of the 22 taxa observed at inactive sites, 19 showed a restricted occurrence in one region, including the isopod Munnopsidae fam. inc. (DZMB_2021_0007) at the RTJ, the Bryozoan Cheilostomatida fam. indet. (DZMB_2021_0009) on the SEIR and the fish Histiobranchus gen. inc. on the CIR; the remaining three taxa were restricted to two regions each (Table 7). Fifteen taxa showed a spatial distribution across two regions and only Synaphobranchidae gen. indet. showed a widespread distribution in all three regions, but this taxon is not restricted to inactive vent fields and was also observed in active vent fields. The taxa at inactive areas show highly localised distribution patterns in low to medium abundance (Table 7). In addition and in contrast to the high number of shared taxa at active vent fields in this study and beyond the INDEX area (Breusing et al. 2015, Sun et al. 2020), the inactive vent fields had a considerably lower number of shared taxa between inactive sites and no widespread distribution of taxa across the INDEX area.
The non-vent area showed the highest species diversity in medium to low abundance with a high number of locally-restricted taxa (Table 8). Eighty-two taxa occurred in one region, 39 in two regions and only 13 taxa were observed throughout the INDEX area, the majority in medium to low abundance (Table 8).
In the Indian Ocean, three additional licence areas for polymetallic sulphides have been issued to China on the SWIR, India on the southern CIR and SWIR and Korea on the CIR, with a number of shared species between the licence areas and hydrothermal vent fields outside exploration claims (Nakamura et al. 2012, Zhou et al. 2018, Sun et al. 2020). For example, the gastropod Chrysomallonsquamiferum has been found in both the Chinese and the German exploration claim areas in addition to the Solitaire vent field outside exploration areas (Chen et al. 2015). The low connectivity of the known populations at these three vent sites in the Indian Ocean, of which two are within national licence claim areas, has led to classification of this taxon as endangered on the IUCN Red List (Sigwart et al. 2019). The IUCN Red List might, therefore, be used to draw attention to vulnerable deep-sea habitats and serve as a basis for protecting them (Sigwart et al. 2019). To clarify the population connectivity of C.squamiferum and other locally-restricted species, it is necessary to conduct biodiversity assessments in additional hydrothermal vent areas.
Other taxa, such as Rimicariskairei, show a greater connectivity and a more widespread distribution across spatially-separated vent fields in this yet undisturbed environment (Hashimoto et al. 2001, Zhou et al. 2018, Gerdes et al. 2019).
Although potential mining activities are focusing on inactive hydrothermal vents, they could affect nearby active hydrothermal vents and the surrounding non-vent area (Levin et al. 2016, Miller et al. 2018, Van Dover 2019).
Mitigation strategies to avoid 'serious harm' to the environment include Environmental Impact Assessment studies (EIA), which require baseline studies for time series and monitoring to understand and explain succession, resilience and the recovery potential of the fauna against anthropogenic disturbances (Gollner et al. 2017, Van Dover 2019).
The impact of mining activities for inactive hydrothermal vent sites is far from understood due to a lack of qualitative and quantitative studies as pointed out in several reviews addressing the potential consequences of mining-related disturbances (Van Dover 2014, Miller et al. 2018, Van Dover 2019). For the non-vent areas in the vicinity of hydrothermal vent fields, mining effects are even less studied and require proactive research (Van Dover 2014).
This megafauna catalogue is a valuable baseline study that offers an impression of the diversity present within the GLA, which can serve as a basis for monitoring the deep-sea benthic megafauna in the context of potential SMS mining activities. A drawback of this fauna catalogue is that the occurrences of taxa are based chiefly on imagery alone; additional physical samples are needed for taxonomic and molecular confirmation.
