nudibranch Ceratosoma sp. Family Chromodorididae updated Oct 10 Where seen? This large chunky hard nudibranch is sometimes seen among coral rubble and reefs on our Southern islands. Usually several are seen at the same time, and then none for a while. Features: 6-8cm long. The hard body is long and narrow with lobes sticking out on the sides, and a long tail. The lobes are armed with glands that secrete distasteful substances to discourage predators. There is a large shield in front of the feathery gills on its back. Like other members of the Family Chromodorididae, the Ceratosoma nudibranch absorbs the toxic chemicals in their sponge food and incorporate these chemicals into the mantle glands. What does it eat? It is eats sponges. |
