This is the Blue Dragon nudibranch. It spends its life floating on the surface of the ocean. They feed on the poisonous Man of War Jellyfish, collecting the animal&#x27;s toxins and storing them in little sacs on the end of their feather-like &quot;fingers.&quot; The Blue Dragon can produce a much more powerful and deadly sting than the Man of War due to its ability to store the poison.
