Octopus on Anemone
This octopus was sitting on a bed of Plumose Anemones (Metridium senile), eyes closed. After I shot the first frame, he turned almost completely white, and I left him alone.

Anemone Eating Shrimp
This Metridium anemone is catching and feeding on the tiny Euphausid shrimp that were everywhere the night I shot this image. Swimming along the bottom was like walking through clouds of gnats, the shrimp were so thick. They were especially drawn to my dive light, which, when I held it up near an anemone, ended unfortunately for the shrimp.
