Order Ascidiacea (Tunicata)

These come in a variety of colours and form, occuring in dense mats and are often mistaken for sponges.

They can usually be distinguished by being softer, more jelly-like, without siliceous or calcareous spicules and lacking a canal system.

Their free-swimming tadpole-like larvae are interesting because they have a primitive form of notochord which degenerates after metamorphosis.
