Data are from refs. 7–13 and 18–22; www.biobase.org/cloftep/; L. Rocha, personal communication for Brazil; and unpublished observations at all the islands except St. Paul.
Family groups: Group I, 10 families with the highest average levels of species richness in both the regional faunas and (except for the Muraenids) the endemic fauna; Group II, 9 families (Apogonidae, Bothidae, Callionymidae, Gobiesocidae, Holocentridae, Monacanthidae, Pomacanthidae, Sparidae, and Tetraodontidae) and 13 families (Belonidae, Cirrhitidae, Congridae, Creediidae, Dactyloscopidae, Kuhliidae, Kyphosidae, Mullidae, Ogcocephalidae, Ophichthidae, Paralichthyidae, Scaridae, and Synodontidae) with moderate and low levels of species richness, respectively, in the endemic and regional faunas; Group III, 31 families lacking island endemics and with low levels of species richness in regional faunas.
