Épines dorsales (Total) : 12; Rayons mous dorsaux (Total) : 12 - 13; Épines anales: 3; Rayons mous anaux: 5. Pinkish with faint dusky bars; Y-shaped dark bar between soft dorsal and anal fins (Ref. 4313).

Biologie     Glossaire (ex. epibenthic)

Adults are found in soft bottom areas of the continental shelf and upper slope. They feed on both benthic and pelagic organisms (crustaceans, fishes, cephalopods, and echinoderms) (Ref. 4570). The reproductive mode is a zygoparous form of oviparity, intermediate between oviparity and viviparity (Ref. 36265, 79712). Larvae and juveniles are pelagic (Ref. 4570). Anterolateral glandular grooves with venom gland (Ref. 57406). Sold fresh (Ref. 27121).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larves

The reproductive mode is a zygoparous form of oviparity, intermediate between oviparity and viviparity (Ref. 36265, 79712). Eggs covered with gelatinous material are fertilised in the ovary. Eggs are released into the seabed at various stages of development and larvae assumes a planktonic existence once the gelatinous covering dissolves (Ref. 31150).
