Siphonaria compressa

Unknown

Overview

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

Siphonaria compressa faces severe population decline due to coastal development and habitat modification along its restricted range. The species is particularly vulnerable to sea-level rise and increased storm intensity associated with climate change, which directly impacts its intertidal rocky shore habitat. Pollution from urban runoff and marine debris further degrades the water quality in its limited coastal range.

Threat summary

Habitat

Siphonaria compressa inhabits rocky intertidal shores and tide pools along exposed coastlines. The species requires specific microhabitat conditions within the splash zone where it grazes on algae and biofilms on rock surfaces.
