Dorsale stekels (totaal) : 2; Anale stekels: 0. Snout short, blunt; terminal and lateral scutes large, blunt; undersides of snout, mandible, most of the suborbital, and part of the lower margin of the preopercle naked. Body scales with sharp, slender spinules in 4 to 16 parallel rows. Pyloric caeca 25 to 28. Overall color is brown; abdomen bluish; gill membranes blackish; fins dusky, first dorsal fin blackish distally; oral and branchial linings blackish.
Uncommon in depths shallower than 400 m. Frequents waters of 5-7°C. Polychaetes and euphausiids compose 30-60% of the diet of specimens from Japan, and prawns of minor importance.
