Kurzbeschreibung
Morphologie | Morphometrie
Afterflossenweichstrahlen: 112 - 145. Distinguished from other species of the genus by having the following combination of characters: boldly contrasting color pattern of irregular, dark blotches on the back and sides followed by posteriorly by a long pallid area extending far onto the caudal peduncle; pectoral and anal fins translucent; anal-fin rays 112-154 with mean 133.2; vertebral count to base of last anal-fin ray 52-57 with mean 54.5; a relatively deep body, 21-33% of distance to origin of dorsal filament; body depth below origin of dorsal filament less than or equal to postorbital distance (Ref. 78211).
Reported to feed on benthic invertebrates (Ref. 78211).
