Most jellyfishes are passive drifters that feed on living or dead preys: small fish, eggs, zooplankton and other invertebrates that become caught in their tentacles. Preys are brought (by tentacles, if they have any) into the cavity, called coelenteron, where it is digested.
Jellyfishes have cells called cnidocytes, which contain nematocysts, and located usually on their tentacles, mainly. Whenever a prey comes in contact with cnidocytes, hundreds to thousands of nematocysts' filaments are ejected into the prey's direction. These stinging cells are thus able to latch onto the prey, and the tentacles, or the oral arms (developed from the manubrium) bring the prey item into their mouth for digestion.
