Nembrotha cristata is a species of colorful sea slug, a dorid nudibranch, and a marine gastropod mollusk in the family Polyceridae.


Nembrotha cristata is a large black nembrothid that grows to at least 50 mm in length. Its body is covered with green pustules. The rhinophores and gills are black, edged in green. This species looks similar in appearance to Nembrotha yonowae.


This species occurs in the tropical Indo-West Pacific Ocean.[1] The species lives at depths betweeen three and twenty meters.[2] They live on coral or rocky reefs and can have a lifespan of up to a year.[3]


The bright colors of the slug help defend against predators. They propel themselves around by contracting their muscles, moving millions of tiny hairs on their underside. They are hermaphrodites, meaning that they fertilize their own eggs.[4] They lay their eggs in the sand in a ribbon like pattern.[2] They incorporate tissues from the jellyfish that they sometimes eat in order to deliver a painful sting.[5]
