Swimming tunicates {larvacean} {apendicularian} (Larvacea) can have oval bodies, movable tails, and notochords. Every few hours, they make 2-centimeter-diameter gelatin mass around body, in which they trap plankton. Mucous mass sinks to bottom, carrying phytoplankton carbon molecules from carbon dioxide. Larvaceans make no buds, only use sexual reproduction, and are mostly hermaphrodites. Sperm release first. Breaking body wall releases eggs and causes death.
