Description synthétique
Clés d'identification | Morphologie | Morphométrie
Robust body with rounded snout; eye diameter much shorter than snout; opercular spine strong; 2 median and a pair of basibranchial tooth patches; 7-11 developed rakers on anterior gill arch; pelvic fin rays flattened distally and somewhat thicker in males (Ref. 34024).
Rare species (Ref. 34024). Stomach remains include crustaceans (benthic isopod Storthyngura sp. 1.5-2.5 cm long) and an unidentifiable isopod) (Ref. 75736). Reproductive strategy possibly similar to other members of this family featuring oviparity, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).
