It's amazing how many Anthopleura elegantissima (Pink-tipped Green Anemone) can gather together on one beach-- thousands!

On vertical wall below dock. Wish I'd got a good shot of the group, not just an individual. Long-stalked; wasn't 'shy' like an anemone usually is.
If you think its our only species of zoanthid, for which I originally hoped, here are some ID sources:
1) Lamb and Hanby p. 88
A. aureoradiata on the right, I think the one of the left with pale tentacles might be another species. Second photo shows the same ones, with tentacles retracted. Amongst pebbles in a small rock pool at edge of estuary.
Sea anemones are a group of water-dwelling, predatory animals of the order Actiniaria. They are named for the anemone, a terrestrial flower. Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia. Anthozoa often have large polyps that allow for digestion of larger prey and also lack a medusa stage. As cnidarians, sea anemones are related to corals, jellyfish, tube-dwelling anemones, and Hydra.
