Recently, scientists documented a unique species of sea slugs from the Visakhapatnam coast.

About Sea Slugs:

  • Sea slugs belong to Phylum Mollusca and Class Gastropoda. They look like naked snails, i.e., without shells.
  • Sea slugs are found in the sea and some slugs live on land as well.
  • A unique species of nudibranch sea slugs were documented on the Visakhapatnam shore.
  • These sea slugs are found in places with abundant prey bases which may vary from sponges, hydroids and algae.
  • The nudibranchs are usually found in coral reefs and their presence is a significant indicator of a strong coral ecosystem.
  • They mainly feed on algae and are usually seen in large numbers when there is an algal bloom.
  • Most nudibranchs are active throughout the day, but some species are also nocturnal.


Q1) What are Molluscs?

Molluscs are a clade of organisms that all have soft bodies which typically have a "head" and a "foot" region. Often their bodies are covered by a hard exoskeleton, as in the shells of snails and clams or the plates of chitons.
