Size / Vikt / Age
Maturity: Lm ? range ? - ? cm
Max length : 40.0 cm TL hane/ej könsbestämd; (Ref. 1371)
Taggstrålar i ryggfenan (totalt) : 2; Taggstrålar i analfenan: 0. Head large, completely scaled, including the ventral surfaces of the snout; snout short, narrow, with stout scutes at its tip and lateral angles; mouth small, restricted laterally. Scales with numerous (over 100 in large specimens) short, stout spinules arranged in V-shaped rows. Pyloric caeca short, 10 to 15. Overall color is medium to dark brown; fins generally blackish.
Feeds primarily on benthic organisms, especially gammarian amphipods and, to a lesser extent, lamellibranchs, copepods, polychaetes, ostracods, isopods mysids, Natantia, and echinoderms (Ref. 1371). Minimum depth record from Ref. 1371.
