Carronella pellucida

Carronella pellucida is a species of sea slug, an aeolid nudibranch, a marine heterobranch mollusc in the family Flabellinidae. It is occasionally referred to as the milky white sea slug, the pellucid aeolid, or the red-gilled nudibranch, though these names are not commonly accepted in formal settings.

Description

The bodies of the cerata are bright red due to the presence and appearance of the nudibranch's digestive glands. These cerata are arranged in distinct clusters which extend from several common stalks known as peduncles.



The maximum recorded body length is 30 mm or up to 40 mm.
