How do corals feed?

Corals are carnivore; they catch preys and animal particles that touch their tentacles, which are armed with 2 types of cnidocytes (stinging and/or sticking cells), then the tentacle bends, or convolves, bringing the caught food to the hypostoma (the mouth) wich is ingested through the pharynx and reaches the coelenteron, where it's digested with enzymes.

Many corals obtain food also from photosynthetic organisms that live in mutual symbiOSis inside them, called zoochlorellaeand zooxanthellae.
