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.
