Distinguished by the following characteristics: dark brown or violet-black body color, darker fins; oval body, compressed, depth contained 2.4-2.7 times in the standard length; head length 3.0-3.4 times in SL; distinctly convex dorsal head profile; nostrils subequal in juveniles, diameter of posterior nostrils twice that of anterior nostrils in 56 cm SL adults; small mouth, oblique, pair of short canines at front of each premaxilla (Ref. 89707).
An anti-tropical species. Occurs on rocky or soft (silty-sand or mud) bottoms. The young have been observed to feed on zooplankton in the water column; feeding of adults has not yet been discovered.
