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: -Nutrition. Most cnidaria feed on prey that come into contact with their tentacles. These include the larger of the protists, various worms, crabs, other cnidaria and even fish. Some groups such as coral live symbiotically with algae, mostly Dinoflagellata but sometimes Chlorophyta.

Detailed explanation-3: -Cnidarians are carnivorous – feeding on zooplankton, crustacea or small fish. They trap their food in their tentacles, which are armed with unique cells – cnidocytes – containing coiled stinging threads.

Detailed explanation-4: -All cnidarians are carnivores, meaning that some form of meaty food is the basis of their diet. The meat consumed varies depending on the size of the species eating it, from microscopic zooplankton (animal larvae) and phytoplankton (plant larvae) to small fish.
