Porania stormi

Local name: nåldyna

Unknown

Overview

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

Porania stormi faces severe threats from deep-sea fishing activities, particularly bottom trawling, which directly damages the seafloor habitats where this starfish resides. Climate change poses additional risks through ocean acidification and warming temperatures that affect the species' calcium carbonate skeleton and alter deep-sea ecosystem dynamics. The species' limited distribution and slow reproductive rate make populations particularly vulnerable to localized disturbances.

Threat summary

Habitat

Porania stormi inhabits deep-sea environments on the continental shelf and slope, typically found on soft sediment substrates at depths ranging from 200 to 800 meters. The species occurs in cold-water marine ecosystems along the Norwegian coast and adjacent North Atlantic waters.

Why is nåldyna classified as Endangered?
nåldyna is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Porania stormi faces severe threats from deep-sea fishing activities, particularly bottom trawling, which directly damages the seafloor habitats where this starfish resides. Climate change poses additional risks through ocean acidification and warming temperatures that affect the species' calcium carbonate skeleton and alter deep-sea ecosystem dynamics. The species' limited distribution and slow reproductive rate make populations particularly vulnerable to localized disturbances.
Where does nåldyna live?
nåldyna occurs in Canada, Faroe Islands, Ireland, Norway, and Sweden. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
