Phlebobranchs group sea squirts (sessile tunicates) with undivided bodies and gonads on one side near the digestive tract. In this group, there are solitary and social 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.
