Yes, a cnidarian is an invertebrate.
the most complex group of invertebrate is cnidarians
Cnidarians.
Cnidarians are invertebrate animals with stinging cells and include the jellyfish, coral, and annenomes. Cnidarians are most commonly found in salt water oceans however the hydra is found in fresh water.
I assume you mean sponges, and they are obviously invertabrates (they lack a back bone).
Most cnidarians have tentacles with stinging cells surrounding their mouth. The mouth is the only body opening. All cnidarianshave radial symmetry.
Any member of the Phylum Cnidaria is an invertebrate as they do not have a backbone or spinal cord. Cnidarians include jellyfish, polyps (e.g. Corals and anemones) and other marine stingers. Vertebrates include only some members of the Phylum Chordata: specifically, mammals, birds, fish, reptiles and amphibians.
A collentrate is an invertebrate.
An invertebrate is an organism that lacks a backbone. The 6 groups of invertebrates are sponges, cnidarians, worms, mollusks, echinoderms and arthropods.
Cnidarians are a phylum of invertebrate animals that includes jellyfish, corals, and sea anemones. They are characterized by their radial symmetry and specialized stinging cells called cnidocytes, which they use to capture prey. Cnidarians are found in marine environments around the world.
Cnidarians belong to the animal phylum Cnidaria. They are characterized by their radial symmetry, tentacles armed with stinging cells called cnidocytes, and a simple sac-like body structure. Examples of cnidarians include jellyfish, corals, and sea anemones.
Cnidarians have strings to get their food also to get protection they are also divided in three groups what they also have that sponges dont is string cells and they have a simple nervous system . On the other hand,Sponges have No symmetry they never move and have no organs . Thanks for using my answers to help you with your science work .
All animals in the invertebrate kingdom. This includes all insects.
