What do sea anemones use to feed?
Anemones are carnivorous, feeding on tiny plankton or fish. Their stinging tentacles are triggered by the slightest touch, firing a harpoon-like filament called a nematocyst into their prey. Once injected with the paralyzing neurotoxin, the prey is guided into the mouth by the tentacles.
How do anemones catch their food?
Anemones have rings of tentacles surrounding their central mouth. Tentacles have specialised stinging cells called nematocysts. They use these to immobilise their prey so that the tentacles are then able to move the food into the mouth. The extending tentacles can also be used to catch passing food as it drifts past.

Are sea anemones raptorial feeders?
Among the raptorial feeders is a nudibranch species called Phidiana crassicornis. Phidiana crassicornis feeds on cnidarians, and the fine cerata that cover the dorsal surface are packed with the intact and functional nematocysts of the sea anemones and other cnidarians it feeds on.

How do sea anemones use their stinging tentacles?
Sea anemones use their stinging tentacles to capture prey. They feed on crustaceans, small fish, and occasionally mollusks and sea urchins. The stinging tentacles of the sea anemone provide a method of capturing prey, as well as protection from predators. The tentacles are quite similar to that of their close relative, the jellyfish.
Do sea anemones live in cold water?
