Anthopleura Xanthogrammica
(Giant Green Anemone)
Anthopleura Xanthogrammica are generally found on the west coast of Northern and Central America, from Alaska south to Panama. These creatures are found on the rocky shores. These creatures have to compete for space along the rocky shores. They are usually found in cold waters and high wave activity, and are usually found in mussel beds along the rocky shore. The Green Anemone are in danger for waste oil, coastal development, population. The Sea Anemone are also at risk because of humans, and human interactions on the rocky shore. The Giant Green Anemone has algae living inside of it. Having the algae in there guts, allows them to gain extra nutrients.
