This is a Green Anemone (Anthoopleura xanthogrammica). I photographed this at Olympic National Park in Washington State at Ruby Beach. It is a large predatory marine invertebrate found in the rocky tide pools of the Pacific coast of North America. It can live up to 150 years in the wild but only about half of that in captivity. It uses its stinging tentacles called nematocysts to paralyze their prey, then surround them to eat them. They primarily eat crabs, mussels, sea urchins and small fish. This was shot at low tide while it was still completely submerged.
Nikon D-3 camera body, Nikon 200mm macro lens, f/4.5, 1/50 sec. ISO 200 on a tripod.
