Tunicates  (Subphylum Urochordata )

Commonly called tunicates, urochordates or sea squirts. they vary greatly in color and shape but generally they can be recognized by the presence of an in siphon and out siphon. They are asexual, producing a tadpole like swimming larva. The larval stage ends when the tunicate finds a suitable rock to affix to and cements itself in place. The larval form is not capable of feeding, and is only a dispersal mechanism. Many physical changes occur to the tunicate's body, one of the most interesting being the digestion of the cerebral ganglion previously used to control movement. From this comes the common saying that the sea squirt "eats its own brain". Due to their spinal column, Sea squirts are more closely related to fish, birds, and people than worms, sea stars, or other invertebrates and are not technically classified as invertebrates.
