Overview

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

Cerithiella metula faces significant pressure from coastal development and marine pollution throughout its limited range in European waters. Bottom trawling and dredging activities directly destroy the sandy and muddy substrates where this marine gastropod lives and feeds. Ocean acidification poses an emerging threat to its calcium carbonate shell formation, while warming sea temperatures may alter the distribution of its preferred benthic habitats.

Threat summary

Habitat

This marine gastropod inhabits sandy and muddy substrates in shallow coastal waters and continental shelf areas of the northeastern Atlantic. It typically occurs at depths ranging from the intertidal zone to approximately 200 meters, where it feeds on organic matter in the sediment.
