Species Clavelina lepadiformis (Light bulb tunicate)

Small individuals (maximum 4 cm) are grouped and translucent up to several hundred individuals colonies, 15 to 20 cm in size.
A gill structure is always visible white or yellow forming ribs or slits. Two longitudinal lines, on each side run from bottom to the top of the animal.
At the top is the mouth siphon (water inlet) while the cloacal siphon (outlet water) is lateral and slightly lower. Both are circled with a thin white line, with slightly crenellated lobes for the mouth siphon which is again circled in white a little lower. The number of gill slits varies from 10 to 17 lines. 

Other similar tunicates, like Clavelina dellavallei, Pycnoclavella nana and  Diazona violacea have less marked white lines, less transparent bodies, more transversal white lines or different shaped openings.
