The two body forms in the phylum Cnidarian are the polyp and medusa. Polyps are usually stationary, with a cylindrical body and tentacles surrounding a central mouth. Medusas are free-swimming and have a bell-shaped body with tentacles hanging down.
Any of various invertebrate animals of the phylum Cnidaria, characterized by a radially symmetrical body with a saclike internal cavity, and including the jellyfishes, hydras, sea anemones, and corals, are called cniderians.There are about 9000 species of cniderians and they are mostly marine aquatic invertebrates. They possess specialized stinging cells known as cnidocytes which are borne on their tentacles. Cniderians range in size from microscopic to more than 100 feet (30 m). Cniderians occur in polyp and medusa forms.
The word cnidarian is a very unique word that begins with two consonants. One of only two in the entire English language that begins with 'cn' producing the same sound as the letter 'n' alone. Similar in prefix pronounciation to "gnat" or "knight".Addition:Cnidarians take their name from cnidocyte cells, most of which contain a nematocyst - a stinging cell that injects a toxin. Only Cnidarians have nematocysts.All cnidarian forms are either a sedentary polyp or a floating/free-swimming medusa. They have no excretory or respiratory system.
The evolutionary significance of Cnidarians is that they were the first animals to move. As for Porifera, they were the first animals on Earth.
