Hathrometra tenella

Local name: spenslig fjäderstjärna

Unknown

Overview

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

Hathrometra tenella faces significant pressure from deep-sea fishing activities, particularly bottom trawling, which physically damages or destroys the seafloor communities where these crinoids attach. Climate change-induced ocean acidification poses an additional threat by weakening their calcium carbonate skeletal structures. The species' restricted depth range and slow growth rates make populations particularly vulnerable to localized disturbances and recovery is extremely slow following habitat damage.

Threat summary

Habitat

This delicate feather star inhabits deep-sea environments on continental slopes and seamounts, typically found at depths between 200-1000 meters. It attaches to hard substrates including rocky outcrops and coral frameworks in cold, nutrient-rich waters of the North Atlantic.
