Anthopleura elegantissima “Aggregating Anemone” Anthozoa
Olympic National Park, WA
June 1, 2013
A very common intertidal resident here in the Puget Sound and on the open coast. If it’s big and green, it’s Anthopleura xanthogrammica. If it’s white and has very fine tentacles (usually subtidal, not intertidal) then it’s Metridium. Now you can identify 90% of the anemones you find in your backyard!
