Light Bulb Seasquirt

Light bulb sea squirt Clavelina lepadiformis are conspcious transluscent animals living in colonies attached to rocky substrate and growing up to 20 mm in height.

They are a delicate sublittoral species which are very sensitive to exposure by the tide.  The animals brood their eggs and young within the 'body' cavity which can be seen by the naked eye.  The animal gets its name from white lines, which are present around the opening of the seasquirt and in the body cavity as long lines extending from the top to bottom which give the seasquirt a light bulb appearance.
