Creature Feature: Giant Green Anemone

The Giant Green Anemone (Anthopleura xanthogrammica) or sa’ro’ (anemone) in the Yurok language is found in the Pacific Ocean from Alaska to Panama.
 
They are carnivores, feeding on crabs, mussels, small fishes and sea urchins.
 
Much of their green color comes from symbiotic microorganisms, microalgae and dinoflagellates, which live in the tissues of the anemone and photosynthesize.
 
The rocky shore is a fragile ecosystem. Anemones are in danger from pollution, as well as being disturbed or crushed by humans. If you visit a tide pool, watch out for anemones!
