General characteristics Chordata Urochorda Expect for Larvacea, the notochord only exits in the tail of larvae. The adults process no notochord. (Urochora) Adult is enclosed in a sac-like tunica composed of tunicin secreted by the integument. (Tunicata) Without sensory organs and tubus medullaris in the adult, and with an open circulatory system. Usually hermaphrodites, with sexual or budding reproduction
