Environment: milieu / climate zone / depth range / distribution range Ecología

marino batidemersal; rango de profundidad 71 - 766 m (Ref. 10004). Deep-water; 22°N - 10°S

Distribución Países | Áreas FAO | Ecosistemas | Ocurrencias, apariciones | Point map | Introducciones | Faunafri

Indo-West Pacific: widely distributed but with spotty records from Tanzania, the Gulf of Aden, India (Gulf of Mannar, Bay of Bengal), Andaman Islands, Viet Nam, and the Philippines. The immense range of this species is striking compared to the limited ranges of other members of the genus.

Length at first maturity / Tamaño / Peso / Age

Maturity: L_m 15.5, range 15 - 16 cm
Max length : 23.0 cm TL macho / no sexado; (Ref. 244); 24.0 cm TL (female)

Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 0; Espinas anales: 0. Caudal fin without a rippled dorsal margin and ventral lobe but with a strong subterminal notch; vertebral axis of caudal fin little raised above body axis (Ref. 13566). Dark brown with blackish markings on dorsal fins (Ref. 13566).

Occurs over muddy bottoms, on the upper continental and insular slopes and outer shelves (Ref. 244). Feeds mainly on small bony fishes and crustaceans, with squid a lesser item in the diet (Ref. 244). One of the two smallest living sharks (Ref. 13566). Ovoviviparous (Ref. 50449), with 1 to 2 pups in a litter (Ref. 244).

Life cycle and mating behavior Maturities | Reproducción | Spawnings | Egg(s) | Fecundities | Larva

Ovoviviparous, embryos feed solely on yolk (Ref. 50449). 1-2 pups per litter, size at birth about 11 cm (Ref. 244).
