Among the largest echinoderms were some extinct (fossil) crinoids (sea lilies), whose stems exceeded 20 metres (66 feet) in length. In the early part of the 19th century, Echinodermata was recognized as a distinct group of animals and was occasionally associated with the cnidarians and selected other phyla in a division of the animal kingdom known as the Radiata; the concept of a superphylum called Radiata is no longer valid. Development is intermediate including characteristic larvae which undergo metamorphosis into the radially symmetrical adults.

Echinoderms are an exclusively marine phylum with four distinctive characteristics:Adult echinoderms are radially symmetrical, usually with a fivefold pattern, however, they are considered to be bilaterally symmetrical animals because they start off as bilateral larvae, such as the bipinnaria larva (sea star larva, left) and pluteus larva (brittle star larva, right) shown in A well-developed respiratory tree is present. Echinoderms serve as excellent model systems for developmental biology due to their diverse developmental mechanisms, tractable laboratory use, and close phylogenetic distance to chordates. 3 Inch Plastic Stencils, Your email address will not be published.
