Blue sea squirts, Rhopalaea sp.Tunicates are marine invertebrates. Some are solitary while others reproduce by budding and become colonies. They are marine filter-feeders. Most adults are permanently attached to the substrate. Salps, however, swim freely. During their larval stage, tunicates have a primitive notochord and resemble a tadpole.
