Aplousobranch sea squirts gallery


Aplousobranchs group sea squirts (sessile tunicates) whose body is divided into 2 or 3 distinct parts (thorax, abdomen and post-abdomen). In this group, there are social and compound ascidians. Tunicates are marine animals. Some live fixed, others swim in open water and some are solitary and others form colonies. Their body is surrounded by a more or less cartilaginous tunic (from the Latin tunica = tunic). Their tadpole larvae have a central axis or chord in the tail, an outline of the spine, axis which they generally lose in the adult stage.
