Sea anemones are flower-like marine invertebrates of the order Actinaria. Named after a terrestrial flower, the anemone, these aquatic animals are classified with the corals in the Class Anthozoa, which means &lsquo;flower animals&rsquo;.&nbsp; They range in size from less than 1,25 centimeters to nearly two meters in diameter.

A sea anemone is basically the typical polyp: a small sac, attached to the bottom by an adhesive foot, with a column shaped body ending in an oral disc. The mouth is in the middle of the oral disc, surrounded by tentacles. Anemones have a range of ten tentacles to hundreds.

The tentacles are armed with many cnidocytes, which are unique cells that function as a defense and as a means to capture prey. Cnidocytes contain cnidae, capsule-like organelles capable of everything. The cnidae that sting are called nematocysts. Each nematocyst contains a small vesicle filled with toxins&mdash;actinoporins&mdash;an inner filament and an external sensory hair. When the hair is touched, it mechanically triggers the cell explosion that fires a harpoon-like structure. This structure attaches to organisms that trigger it, and injects a dose of poison in the flesh of the aggressor or prey. This gives the anemone its characteristic sticky feeling.

The internal anatomy of anemones is very simple. There is a gastrovascular cavity, which functions as a stomach. This cavity has with a single opening to the outside, which functions as both a mouth and an anus.
