Eurynome spinosa

Local name: långhornad knölkrabba

Unknown

Overview

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

The långhornad knölkrabba faces significant pressure from bottom trawling and dredging activities that destroy its rocky reef habitats and directly remove individuals from populations. Climate change-induced ocean warming and acidification threaten to alter the species' preferred cold-water environments and affect the availability of its prey species. Coastal development and pollution from agricultural runoff further degrade the shallow marine ecosystems this crab depends upon for feeding and reproduction.

Threat summary

Habitat

This species inhabits rocky reefs, kelp forests, and hard substrates in shallow to moderate depths of the North Atlantic, typically found among crevices and under rocks where it can shelter while foraging. It prefers cold-water environments with strong currents that bring abundant plankton and organic matter for feeding.
