About Sea Slug

  • Sea slugs, also known as Nudibranchs, are soft-bodied marine molluscs found in all the world’s oceans, from shallows to the deep sea. 
  • They belong to Phylum Mollusca and Class Gastropoda.
  • They look like naked snails, i.e., without shells.  
  • These slow-moving grazers consume algae, sponges, and other small invertebrates, showcasing a range of feeding habits.
  • They are usually found in coral reefs, and their presence is a significant indicator of a strong coral ecosystem.
  • Sea slugs are renowned for their vibrant colours and intricate patterns, which often serve as warning signals to predators due to their toxicity. 
  • They get their toxicity from the creatures they eat, and some sea slugs can even keep the stinging cells of jellyfish inside their bodies.
  • Beyond their striking appearance, sea slugs possess other intriguing traits. 
    • Some can photosynthesise, producing their own food with sunlight. 
    • Others regenerate lost limbs, and a few can steal genes from their prey and incorporate them into their DNA.
  • Most sea slugs are active throughout the day, but some species are also nocturnal.
