Bluebell sea squirts (2nd of 3)

Bluebell sea squirts

Bluebell or Clavelina sea squirts grow as a group, with individuals connected by a common base. Sea squirts feed by taking in water through an inhalant siphon. The water enters an internal filter compartment, where food particles are removed and forcibly expelled through an exhalant siphon.
