Sea Anemone Info Sea anemones are colorful polyps named after an equally colorful terrestrial flower, anemone. They are water-dwelling, filter feeding animals belonging to the phylum Cnidarian Sea anemones are found in sizes ranging from less than 1¼ cm (½ in) to nearly 2 m (6 ft. ) in diameter. They lack locomotive ability, hence spend most of their life attached to some rock. The only way they can change their habitat is by hitching a ride on a passing crab or they may just detach from the rock and drag themselves in the water.

Sea Anemone habitat Sea anemones usually spend most of their lives in one place, but some have the ability to move. If they do move, they can only travel three to four inches an hour. Sometimes sea anemones hitch a ride on hermit crabs or decorator crabs. If they do that, the sea anemone can protect the crab and if the crab is a messy eater, the sea anemone can pick up bits of food from the crab and eat it.
Characteristics physical features of Sea Anemone Size-Sea anemones can vary in size, depending on the species in question as well as the location of the anemone. At their smallest, sea anemones can be around the size of a pinhead. The biggest sea anemones found to date are 3 feet in diameter. Composition-Sea anemones have a soft, simple polyp-style body with two tissue layers and a central gut cavity. The anemone's "mouth" leads to its gut. The "mouth" of the anemone is surrounded by stinging tentacles which are used to disarm food Weight-The largest sea anemones -- the ones found in tropical waters that can have mouths up to 2 feet across -- can weigh as much as 440 lbs.
What Sea Anemone eats The sea anemone eats small fish and shrimp. The sea anemone captures its prey with its deadly stinging tentacles. The sea anemone's mouth and tentacles are located on the top of its body.
How Sea Anemone reproduce Sea anemones reproduce by budding off baby sea anemones. The babies stay connected to the adult until it is old enough to go out on their own. If a sea anemone is torn apart by rocks, then each part becomes a new sea anemone.
