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 / Size / Вес / Возраст

Maturity: L_m 15.5, range 15 - 16 cm
Max length : 23.0 cm TL самец/пол неопределен; (Ref. 244); 24.0 cm TL (female)

Краткое описание определительные ключи | морфология | морфометрия

колючие лучи спинного плавника (общее число) : 0; колючие лучи анального плавника: 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 | размножение | Spawnings | Egg(s) | Fecundities | личинки

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

Estimates based on models

Preferred temperature (Ref. 115969): 9.3 - 18.6, mean 12.7 (based on 254 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6328 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.1 ±0.3 se; based on diet studies.

устойчивость к внешним воздействиям (Ref. 120179): очень низкий, минимальное время удвоения популяции более 14 лет (Fec=1).

Fishing Vulnerability (Ref. 59153): Low vulnerability (14 of 100).
