Overview

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

The Rough-skinned Sea Anemone faces significant pressure from deep-sea fishing activities, particularly bottom trawling, which physically damages or destroys individuals attached to rocky substrates. Climate change poses an additional threat through ocean acidification and warming temperatures that may alter the species' deep-water habitat conditions and prey availability. The species' extremely limited distribution and slow reproductive rate make populations particularly vulnerable to localized disturbances.

Threat summary

Habitat

This species inhabits deep-sea rocky substrates and hard bottoms in cold temperate waters, typically found at depths between 200-1000 meters. It attaches to stable surfaces in areas with strong currents that provide adequate food flow.
