[Note Guidelines] Photographer's Note
Oklahoma Aquarium.

Anemones are found in coastal areas all over the world, especiallyin warmer waters. They are found both in shallow and deeper water. They attach themselves to shells, rocks, timber, or whatever submerged substrata they can find, by their pedal discs. Some burrow.

On the tentacles are stinging cells or nematocysts. A nematocyst is a small capsule with a thread-like tube coiled inside. When a trigger bristle is disturbed, the coiled tube shoots out and imbeds in whatever triggered it. There is a minute amount of poison injected. The nematocysts are used both for defense and capturing food.

Straight from the camera, sized for upload.
