WebbTunicates are bright bio-luminescent animals and produce a pale blue-green light. Each tunicate draws water from the surrounding sea and generates jet propulsion via atrial syphons at its open end. Tunicates are the only animals in the ocean that move by using fluid jets for propulsion and they survive by using jet propulsion and group behaviour. http://pubs.sciepub.com/ijp/1/2/1/ impulse grapher
