Haystack Rock tidepools- July 2004


Moonglow Anemone
and Sea Squirts

This solitary moonglow anemone was found in the sand at the base of a rock.

The orange organism found in this picture (to the left of the anemone) is colonial ascidian -- also referred to as tunicates or sea squirts. Some sea squirts live individually, others together beneath a common covering, and still others are connected by runners. Physical features of tunicates include a pharyngeal sieve (for filtering food) and a heart.
