These nudibranchs eat stinging celled animals (Cnidarians) such as anemones, hydroids and sea fans or bluebottles. The stinging cells or nematocysts are passed unharmed through the digestive system to the tips of the cerata. WebNudibranchs that feed on hydroids can store the hydroids' nematocysts (stinging cells) in the dorsal body wall. The nematocysts wander through the alimentary canal without harming the nudibranch. Then, the cells are brought to specific places on the creature's hind body. Nudibranches can protect themselves from the hydroids and their nematocysts. long lines for horse training
