背面の脊椎 (合計) : 2; 背鰭 (合計) : 160 - 163; 肛門の骨: 0. Snout short, blunt, with large terminal and lateral angle scutes; underside of the snout, mandible and most of the suborbital, and part of the lower margin of the preopercle without scales. Pyloric caeca 22 to 32. Body scales with sharp, needle-like spinules arranged in parallel rows. Overall color is brownish, abdominal region violaceous; gill membranes blackish; fins dusky, first dorsal fin blackish distally. Also Ref. 2800.
A benthic species found on the continental slope (Ref. 75154). Off Hawaii, individuals reportedly taken in June by the ALBATROSS had been feeding exclusively on small eggs. Mature eggs were found in a specimen taken in August (Ref. 1690).
