Overview

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

Aegires punctilucens 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 preferred sponge prey, forcing population shifts or local extinctions.

Threat summary

Habitat

This nudibranch inhabits rocky intertidal and shallow subtidal zones, typically found on or near encrusting sponges which serve as both habitat and primary food source. It prefers areas with moderate wave action and good water circulation, often occurring in crevices and under overhangs at depths ranging from the low tide zone to approximately 30 meters.
