Anemones are solitary polyp organisms which are supported internally by water. Anemone species are differentiated by the color, shape, placement, and length of the tentacles. These Cnidaria feed off of zooxanthellae within their bodies and need a strong light source in order to survive. They will also take in food by using their tentacles to slowly move the prey to their mouths which is a slit in the center of the body. This single opening also serves as its way of expelling waste. Anemones use tiny stinging cells in their tentalces called "nematocysts" in order to stun their prey. The nematocysts within these tentacles are also used as a defense mechanism. The nematocysts can also disturb human flesh and should be considered dangerous, especially to those that have known allergies. Anemones found in the wild usually have found a crevice to hide their foot, or base, leaving only the tentacles exposed.Some Anemones are shipped in little or no water. Float them for half an hour, discard any water in the bag, then release the Anemone directly into the aquarium.
