Appearance
''Nembrotha cristata'' is a large black nembrothine 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 color, this species is similar in appearance to ''Nembrotha yonowae''.
Behavior
The bright colors of this nudibranch species are a warning to predators . These creatures incorporate stinging cells from the jellyfish that they sometimes eat, and thus the slugs are able to deliver a painful sting. Normally however these sea slugs eat compound tunicates. Like all opisthobranchs, these sea slugs are hermaphrodites. They lay their eggs in the sand in a ribbon-like pattern.
Habitat
This nudibranch species occurs in the tropical Indo-West Pacific Ocean. 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.References:
