Sea squirts are marine animals that live in the depths of the ocean. They are sessile meaning they can't move, or they stay where they are all the time. Some live individually and some live in groups, or colonies. Their body has a protective covering called a tunic. They have two large pores, one to guide water in and one as an exit. They are hermaphroditic, but they also reporoduce by budding.
Another organism is the sub-phylum Urochordata is a Larvacean.
Lancelets are usually found buried deep in the sand and in shallow parts of tropical seas. They provide most of the base for the phylum Chordata. So instead of having a vertebrae they have a notocord. Their digestive system is made up of one simple tube. They also have segmented gonads.
One other organism in sub-phylum Cephalochordata is a X-ray Tetra.
Extra Credit:
