Very similar to the Football Sea Squirt (see next picture), the Lightbulb Sea Squirt, Clavelina lepadiformis, is very common around all British coasts where there is rock to which it attaches itself. It can be found in very shallow water down to about 50m. Each individual in the colony is separate from its neighbours except at the base. It is a seasonal animal growing from an over-wintering bud attached to the rock. Development of the individual “squirts” commences in the winter months and the colony gradually expands during the Spring. However, following production of larva and probably by September at the latest, the colony dies back to leave just a bud again for the following year.
