nudibranch Goniobranchus tumulifera Family Chromodoridae updated May 2020 Where seen? This small colourful nudibranch with a cow-like pattern is sometimes seen on our Northern shores. On coral rubble and rocky shores with sponges and encrusting animals. It was previously known as Chromodoris tumulifera. Features: 2-3cm. Body broad usually white with black spots. Edges of the body and feathery gills and rhinophores tips yellow or orange. According to Bill Rudman, they have tiny glands around the edge of the mantle that secretes defensive substances to deter predators. What does it eat? Members of the Family Chromodorididae absorb the toxic chemicals in their sponge food and incorporate these chemicals into the mantle glands on their backs where they repel predators. |
