Western Pacific: southern New Guinea, Solomon Islands, and northern Australia (including Western Australia, Ref. 7300).

A little-known reef shark found in shallow water on the continental and insular shelves, but may range in deeper water (Ref. 244). Feeds on small fishes and crabs (Ref. 244). Viviparous (Ref. 50449). Rather skittish and timid when approached (Ref. 244). Probably harmless or minimally hazardous to people (Ref. 244). Utilized for human consumption (Ref. 9997).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00204 (-0.13603 - 0.14012), b=3.22699 (3.14172 - 3.31227), based on LWR estimates for species & genus-BS (Ref. 93245).

Trophic Level (Ref. 69278): 4.5 ±0.8 se; Based on diet studies.

Resilience (Ref. 69278): Very Low, minimum population doubling time more than 14 years (Fec = 1).

Vulnerability (Ref. 59153): High vulnerability (58 of 100) .

Price category (Ref. 80766): Medium.
