Environment: milieu / climate zone / depth range / distribution range
Marine; bathydemersal; non-migratory; depth range 200 - 600 m (Ref. 95664). Deep-water; 8°C - 12°C (Ref. 1371); 35°N - 28°N, 126°E - 139°E (Ref. 1371)

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 36.0 cm TL male/unsexed; (Ref. 1371)
spines: 0. Snout slightly long and pointed, with broad triangular naked areas on the dorsal surface; the terminal scute small, poorly defined in larger individuals. Overall color is light brown with a large ocellated black blotch above and behind the pectoral fin bases; a fainter saddle just below the anterior end of the second dorsal fin extending 2 to 3 rows below the lateral line. The mouth cavity whitish; the gill cavity blackish; the fins generally dusky except for the blackish pelvic fins.
Captured at depths from 200 to more than 600 m (Ref. 95664). Feeds primarily on polychaetes with crustaceans of minor importance (Ref. 1371).
