Tunicate Video Stock Footage

Pyura chilensis is a tunicate that somewhat resembles a mass of organs inside a rock. It is often found in dense aggregations in the intertidal and subtidal coast of Chile and Peru. It is a filter feeder that eats by sucking in seawater and filtering out microorganisms. P. chilensis has some basic characteristics common to chordates, such as the notochord and a perforated pharynx. It is born male, becomes hermaphroditic at puberty, and reproduces by tossing clouds of sperm and eggs into the surrounding water. If it is alone, it will procreate by self-fertilization. Its blood is clear and can contain high concentrations of vanadium, which may be ten million times that found in surrounding seawater, although the source and function of this element's concentrations are unknown.
