(a) Observation sites marked by black burgees. Samples are indicated by A-G. Map adapted from OpenStreetMap-contributor (Open Database Licence (ODbL) 1.0). (b) Number of individuals in schools at different study sites A: Pulau Naira, B: Banda Naira, C: Pulau Banda, D-G: Hatta. Circles indicate individual schools. A total of 31 schools (1 recording per school) were recorded at the study sites. (M) represents the mean value of fish per school ± SEM. (c) Orientation of schooling A. katoptron on the coral reef flat during the night. Pictures were recorded with an internal camera flash. Black bar (1) indicates specimens orientated in one direction (see example in c). Grey bar (2) indicates the opposite direction. White bar (3) indicates specimens in perpendicular orientation. (d) Schooling behavior in A. katoptron on a reef flat during a moonless night. Flash photograph of an A. katoptron school showing the majority of fish moving in the same direction, and a minority positioned in the opposite or perpendicular direction. (e) Bioluminescence of A. katoptron light organs in complete darkness Error bars indicate ± SEM.
