Morphology | Morphometrics
Anterior lobe of pelvic fin nearly as long or longer than posterior lobe of fin; dorsal surface of tail without distinct cross-bars; abdominal area uniformly dark colored and sharply marked off from light interbranchial and cloacal regions (Ref. 31400).
Found in the continental slope (Ref. 31400). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449).
