Overview

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

The Red-fringed Conch faces severe population decline primarily due to habitat destruction from coastal development and limestone quarrying activities that destroy its specialized cave and karst environments. Ocean acidification poses an additional threat by weakening the calcium carbonate shells essential for the species' survival. Collection pressure for the ornamental shell trade has further reduced wild populations in accessible locations.

Threat summary

Habitat

This marine gastropod inhabits shallow coastal waters and intertidal zones, particularly around limestone formations and coral reef environments. The species shows a strong preference for areas with calcium-rich substrates that support shell development and provide suitable feeding grounds.

Frequently asked questions

Why is Red-fringed Conch classified as Endangered?
Red-fringed Conch 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. The Red-fringed Conch faces severe population decline primarily due to habitat destruction from coastal development and limestone quarrying activities that destroy its specialized cave and karst environments. Ocean acidification poses an additional threat by weakening the calcium carbonate shells essential for the species' survival. Collection pressure for the ornamental shell trade has further reduced wild populations in accessible locations.
Where does Red-fringed Conch live?
Red-fringed Conch occurs in Åland Islands, Albania, Austria, Bulgaria, Denmark, and Estonia (plus 17 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Red-fringed Conch?
The main threats to Red-fringed Conch are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
