Common name: Agassiz's Sea Hare

Philinopsis is a genus of headshield slugs, a group of sea slugs that are part of the family Aglajidae. These creatures are known for their unique headshield, which they use to plow through the substrate. They are often found in sandy or muddy bottoms in tropical and subtropical seas. Philinopsis species are interesting for their predatory behavior, feeding on other sea slugs and flatworms. They are not common in the reef aquarium trade, but they can be fascinating subjects for specialized hobbyists interested in a more diverse and biologically rich tank setup.
