Discussion Ideas

  • Read the Nat Geo News article and watch the terrific video above. What are “sea bunnies”?
    • Sea bunnies are a type of sea slug called a nudibranch.
      • The word “nudibranch” combines two ancient words: nudus and brankhia. The Latin word nudus means nude or naked, and the Greek word brankhia means gills. Like many sea creatures, nudibranchs need gills to breathe, and a nudibranch’s gills are not inside its body—the gills are exposed and naked right there on the cute little gastropod’s behind.
      • Take a look at this gorgeous Nat Geo photo gallery of nudibranchs.

  • How do those ears help sea bunnies hear on the seafloor?
    • Those aren’t ears! Those are rhinophores. Rhinophores are organs that help the nudibranch “smell.” Rhinophores detect chemicals in the environment, helping the animal decide whether to pursue a mate, flee a predator, or attack a prey species.


  • Why do sea bunnies shake their little tail?
    • That isn’t a tail! That little “tail,” called a branchial plume, is the nudibranch’s gills. As water moves over the plume, the nudibranch “breathes.”



  • Why are sea bunnies so cute?
    • They look like babies—soft, small, round, and big-headed. Watch this video for a great overview of the evolutionary adaptation of cuteness.
