Overview

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

Cumanotus beaumonti faces significant pressure from coastal development and marine pollution in its limited range along temperate rocky shores. Ocean acidification poses an emerging threat to this nudibranch's calcium carbonate-dependent prey species, potentially disrupting its specialized feeding ecology. Climate-driven changes in sea temperature and current patterns may alter the distribution of its hydroid prey, forcing population declines in areas where thermal tolerance limits are exceeded.

Threat summary

Habitat

This nudibranch inhabits rocky intertidal and shallow subtidal zones along temperate coastlines, typically found on kelp holdfasts and rocky surfaces where it feeds on specific hydroid species. It prefers areas with strong water movement and abundant epifaunal growth, generally occurring at depths from the low tide zone to approximately 30 meters.

Frequently asked questions

Why is Polyp Aeolis classified as Vulnerable?
Polyp Aeolis is classified as Vulnerable because the population is declining and the species faces a high risk of extinction in the medium-term future if current pressures continue. Cumanotus beaumonti faces significant pressure from coastal development and marine pollution in its limited range along temperate rocky shores. Ocean acidification poses an emerging threat to this nudibranch's calcium carbonate-dependent prey species, potentially disrupting its specialized feeding ecology. Climate-driven changes in sea temperature and current patterns may alter the distribution of its hydroid prey, forcing population declines in areas where thermal tolerance limits are exceeded.
Where does Polyp Aeolis live?
Polyp Aeolis occurs in Denmark, Isle of Man, Netherlands, Norway, Sweden, and United Kingdom (plus 1 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
