Tunicate (Oikopleura vanhoeffeni). Oikopleura vanhoeffeni is a species of small tadpole-like tunicate found in the surface waters of world's colder oceans. It creates a mesh (known as a 'house') around its body which it uses to filter minute food particles from the surrounding water. This structure is regularly discarded and replaced.
