Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Indo-West Pacific: widespread; from South Africa to the Philippines; north to Ryukyu Is. and south to eastern Indonesia. However, it may comprise of two closely related species based on genetic findings where the forms possibly differ in the shape of the head and tail and robustness of the bodies.

Size / Weight / Age

Maturity: L m   ?   range ? - 78 cm
Max length : 90.0 cm WD male/unsexed; (Ref. 114953 )

Biology     Glossary (e.g. epibenthic)

Benthopelagic in the open ocean and often aggregating in large shoals (Ref. 114953 ). . Ovoviviparous (Ref. 50449 ).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449 ).

Estimates based on models

Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.01148 (0.00461 - 0.02857), b=2.98 (2.76 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.6   ±0.5 se; based on size and trophs of closest relatives Resilience (Ref. 120179 ):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100). Vulnerability (Ref. 59153 ):  High to very high vulnerability (66 of 100) .
