DescriptionNembrotha cristata is a large black nembrothine ("nembrothid" in much of the literature) that grows to at least 50 mm in length. Its body is covered with raised green nodules. The rhinophores and gills are black, edged in green. Other than the difference in colour, this species is similar in appearance to Nembrotha yonowae.[3]DistributionThis nudibranch species was described from the Philippines. It occurs in the tropical Indo-West Pacific Ocean.[4] It lives at depths between three and twenty meters. These sea slugs live on coral or rock reefs, and have a lifespan of up to a year.[4] BehaviourThe bright colours of this nudibranch species are an aposematic warning to predators. These sea slugs eat compound tunicates. Like all opisthobranchs, they are hermaphrodites.[4] References1. ^Bergh, L.S.R. (1877). Malacologische Untersuchungen, 2. In C.
