Sea squirt. Stalked ascidian,or tunicate,(class Ascidiacea) growing on a reef. Sea squirts filter plankton from the water current which circulates through them. They are sedentary but have free-swimming larvae. Ascidian sea squirts are characterized by a tough outer layer of the polysaccharide tunicin,unlike other tunicates which are less rigid.
