Overview

Catriona aurantia is a species of sea slug, an aeolid nudibranch, a marine gastropod mollusk in the family Trinchesiidae. It was incorrectly synonymised with Catriona gymnota from the Western Atlantic but shown to be a distinct species by DNA analysis.

The orange-tip cuthona faces significant threats from coastal habitat degradation and pollution in its shallow marine environments. Climate change-induced ocean acidification and warming temperatures are altering the delicate marine ecosystems this nudibranch depends on, while coastal development continues to destroy critical intertidal and subtidal habitats.

Threat summary

Habitat

Rocky intertidal zones and shallow subtidal areas with rich algal growth, typically found on kelp forests, rocky reefs, and tide pools in temperate coastal waters. This nudibranch inhabits depths from the low tide zone to approximately 30 meters, where it feeds on hydroids and other small invertebrates.
