Detailed explanation-1: -All cnidarians are carnivorous predators. Jellyfish capture small drifting animals with their stinging cnidocyte-filled tentacles. Even the sessile coral polyps and sea anemones are predators ready to sting prey, grasp it in their tentacles, and push it into their mouth.
Detailed explanation-2: -Cnidarians use nematocysts to catch their food. When touched, the nematocysts release a thread of poison that can be used to paralyze prey. Cnidarians are among the simplest of the so-called “higher” organisms, but are also among the most beautiful.
Detailed explanation-3: -Cnidarians defend themselves and catch prey using their tentacles, which have cells called cnidocytes at their tips. These tentacles, which contain the cnidocytes are found framing the mouth of the Cnidarians, so when going after the prey, it is easy for the Cnidarians to suction and disable its prey.
