cnidarians, such as jelly fish, sea anemones, hydra, and corals, have tentacles surrounding their mouth. they are a hollow-bodied animal with two celled layers that are organ…ized into tissues. the inner layer forms a digestive cavity where food is broken down. A jelly fish. Cnidarian's have a sting cell called a cnidnocyte which is the defining feature.
A cnidarian is an animal with stinging bristles, like a jellyfish,a portoguese manowar, and coral .
If you mean the longest-lived, gold corals and black corals can be 2000 to 4000 years old.
what are some characteristics of cnidarians
the phylum cnidaria consists of about 10,000 species which are mostly marine. the jellyfish and sea anemone belong to this phylum. there bodies are radially symectrical. they …capture there prey by stining them with tentacles, there tentacles have special cells that contains a toxin. the only have one body opening to food and wate exit and enter through the same opening. the are both aquatic floating and sessile (meaning they don't move). they have a simple nervous system. they have s bodt forms polyp or medusa.
This is straight from www.thefreedictionary.com, so I get no credit at all: "Any of various invertebrate animals of the phylum Cnidaria, characterized by a radiall…y symmetrical body with a saclike internal cavity, and including the jellyfishes, hydras, sea anemones, and corals. Also called coelenterate."
Circular,soft body,usually with tentacles; no segments. Cnidarians include: jellyfish, sea anemones, coral animals.

They have limited mobility, they mainly move with the current.
They are polyps or medusas and have radial symmetry. They have a mouth/anus, tentacle, gastrovascular cavity, gastodermis, mesoglea, epidermis, and in polyps, a body/stalk.
The animal kingdom. That´s the way they´re classified. Kingdom Animalia, Phylum Cnidaria.

they have a mouth just like us, that is what helps them to breathe, but they cant breathe if they are out of water unless they are land animals, which most of them probably ar…ent/
Cnidarians are acoelomates... along with Porifera, Ctenophora, and Platyhementhes.
Like all animals; thru their food. They are filter feeders, if that helps. The water carries the little bits of food in their body along with the oxygen they need.
