Description synthétique
Clés d'identification | Morphologie | Morphométrie
Rayons mous dorsaux (Total) : 89; Rayons mous anaux: 74. Body and tail strongly compressed, snout round and short, no spine on tip. Head and body uniformly whitish, margins of median fins light brown, jaws, pelvic fins, mouth and gill cavities deep brown. Peritoneum and stomach deep brown, intestine yellowish.
Body shape (shape guide): fusiform / normal.
A benthopelagic species at bathyal depth (Ref. 56809). Found on the continental slope (Ref. 75154). Rare species (Ref. 34024). Reproductive strategy possibly similar to other members of this family featuring oviparity, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).
