Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Hemitriakis leucoperiptera faces severe population decline primarily due to intensive fishing pressure across its limited range in the western Pacific. The species is particularly vulnerable to both targeted shark fisheries and incidental capture in bottom trawl and gillnet operations. Its slow reproductive rate and late maturity make population recovery extremely difficult once numbers decline.
