What are Sea Slugs?
- Sea slugs are a group of molluscs that live primarily in marine habitats and are slug-like.
- They can be found from the shallow intertidal to the deep sea and from the polar regions to the tropics.
- The sea slugs are rapid hunters and feed upon mobile prey such as other shelled and unshelled sea slugs, roundworms, marine worms, and small fishes.
- So far, 18 species have been discovered across the globe.
- They are distributed in temperate regions of the Indo-Pacific Oceanic realm, but three species are truly tropically distributed, Melanochlamys papillata from the Gulf of Thailand, Melanochlamys bengalensis from West Bengal and Odisha coast and the present species.
