Sea anemones are mostly carnivorous, and their feeding methods and digestive abilities are adapted for intake and processing of live prey. Food is captured in 3 different ways: 1) filter feeding, where small organic particles, both live and dead, are removed from the seawater passing over the outspread tentacles, 2) raptorial capture, where zooplankters and motile benthic prey are caught by the tentacles, and 3) passive capture, where sessile prey are dislodged by foraging predators or wave action and carried onto the tentacles. Any plant matter ingested occurs by this means.
