As an animal biologist, I don't think anemones feel pain. Rather, I think what they react to is instinctual to survival. When poked, I think their reaction is more of a built-in "protection" mode if you will. Like say for instance a nem is getting it's foot picked at by a crab. The nem will close up and after a few days will release its foot and move. Their is neither proof or disproof that nems can feel "pain". However, my hypothesis is that it's not pain they are feeling but a built in "instinct" that helps prevent them from getting eaten.
