The above nudibranch is the Spanish Shawl. So pretty and elegant! Nudibranchs are colored so brightly to help them blend in with flowers. It's also a warning that they may occasionally be poisonous. Why only occasionally? It tuns out nudibranchs can eat poisonous animals (such as poisonous sponges or sea anemones), and then they can store the poisons in their own body and use that against other predators. Oh yeah, they can also be cannibalistic. As a form of sea slug, nudibranchs have to pretty much eat whatever they can find swimming around (since they are slow). It's rough down there folks.
