Indonesian Shortnose Spurdog

Squalus hemipinnis

Declining

Overview

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

Squalus hemipinnis faces significant pressure from commercial and artisanal fisheries throughout its range, where it is caught both as a target species and as bycatch in bottom trawl and longline operations. The species' slow growth rate, late maturity, and low reproductive output make populations particularly vulnerable to overexploitation. Habitat degradation from bottom trawling activities further compounds these pressures by damaging the benthic environments where this dogfish forages.

Threat summary

Habitat

This dogfish shark inhabits continental shelf and slope waters, typically found at depths ranging from 50 to 400 meters over sandy and muddy bottoms. The species prefers temperate marine environments where it forages along the seafloor for small fish, crustaceans, and cephalopods.
