Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Anal spines: 0. Head profile rounded; snout short, blunt. Scales deciduous, with 1 to 3 divergent rows of small, thin spinules uniformly covering almost all of the body; scales absent over most of the snout and in wide patches on the head surrounding large pores of sensory lateralis system. Pyloric caeca rather long and slender, about 9 to 10. Overall color is dark brown to brownish black.
Feeds on fish, copepods and other small invertebrates (Ref. 5097).
