Pempheridae (Sweepers)
Etymology: Pempheris: Greek, pempheris = the name of a fish (Ref. 45335); familia: Name from Greek 'familia' means ‘‘family’’; the Ogasawara Islands include ca. 30 islands, many of them having been given family-like names; for example, Chichi-jima = father island, Haha-jima = mother island, Ane-jima = older sister island. Ototo-jima, where the type specimens were collected, and Ani-jima, where the underwater photographs were taken, refer to younger and older brothers, respectively.

背棘 (总数) : 6; 背的软条 (总数) : 9 - 10; 臀棘: 3; 臀鳍软条: 35 - 36; 脊椎骨: 25. This species is distinguished by the following characters: lateral and ventral body scales are strongly ctenoid, adherent, with distinct basal and distal portions; abdomen cross-sectional outline U-shaped; a large ventral fenestra between coracoid and cleithrum; dorsal-fin soft rays 10; anal-fin soft rays 35-36; pored lateral-line scales 84-88; scale rows above lateral line 14-15; predorsal scales 50-55; circumpeduncular scales 26. Colouration: body orange copper; blackish blotch on fins is limited to tip of dorsal, anal and caudal fins; a distinct blackish blotch on pectoral-fin base (Ref. 123196).
Cross section: compressed.
Schools in underwater rock recesses in groups of up to ca. 10 individuals, associated with very large numbers of Pempheris schwenkii being observed in the same rock recesses (Ref. 123196).
