Requienella seminuda

Unknown

Overview

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

Requienella seminuda faces significant pressure from coastal development and tourism infrastructure along Mediterranean shorelines, which directly destroys its specialized rocky intertidal habitat. Ocean acidification poses an additional threat to this marine gastropod, as changing seawater chemistry affects shell formation and the calcareous substrates it depends upon. Pollution from coastal runoff and marine debris further degrades the pristine rocky shore environments essential for its survival.

Threat summary

Habitat

This marine gastropod inhabits rocky intertidal zones and shallow subtidal areas along Mediterranean coastlines, typically found on hard substrates including limestone and volcanic rock formations. It prefers areas with moderate wave exposure and clean, well-oxygenated waters characteristic of pristine coastal environments.
