خارهاي باله پشتي (کل) : 9; شعاع نرم باله پشتي (کل) : 23 - 26; خارهاي باله مخرجي: 3; شعاع نرم باله مخرجي: 23 - 26. Body uniformly brown to dark brown; caudal fin pale in color (snow white in live fishes). Small, dark spot below and adjacent to axil of pectoral fin. Anterior gill rakers 15-18; posterior 14-16. Snout length 7.9 to 8.2 times in SL. Least depth of caudal peduncle 2.2 to 2.5 times in head length (Ref 9808).
This occasionally schooling species occurs in steep outer reef slopes and drop-offs (Ref. 1602, 48637). Benthopelagic over coral and sand (Ref. 58302). Feeds on zooplankton, particularly large gelatinous forms, and on fish eggs and crustaceans (Ref. 1920). Minimum depth reported taken from Ref. 128797.
