Inter-ambulacral plates in more than 2 rows in extinct forms. New data acquired during the PROMETEO, Biologists and taxonomists study characteristics of the organisms of each phylum in order to categorize organisms effectively. Bilaterally symmetrical with the definite polarity of head and tail ends. They come in a large variety of shapes, colors, and sizes, with more than Urochordates? Deep time and disturbance contribute to tree resolution and may be appropriate taxon.

In the table below, identify each invertebrate by matching it with its characteristics. The phylum echinoderms is divided into five extant classes: Asteroidea (sea stars), Ophiuroidea (brittle stars), Echinoidea (sea urchins and sand dollars), Crinoidea (sea lilies or feather stars), and Holothuroidea (sea cucumbers). The body consists of an aboral cup, the calyx and oral cover or roof, the tegmen, and strongly pentamerous in structures. Each arm of the starfish has hundreds of tubes with suckers on them to help them navigate over rocks and sand.

Echinodermata Abstract The Phylum Echinodermata, comprising approximately 7,000 living species, and 13,000 fossil species, is epitomized by the familiar sea star, a universal symbol of the marine realm. Echinoderms (sea urchins, sea stars, brittle stars, sea lilies and sea cucumbers) are a group of diverse organisms, second in number within deuterostome species to only the chordates. Echinoderms include animals such as sea stars and sea urchins. Echinoderms also lack a centralized nervous system. Phylum Platyhelminthes (flatworms) characteristics.

Echinoderms are enterocoelous coelomates with pentamerous radial symmetry, without distinct head or brain having a calcareous endoskeleton of separate plates or pieces and a peculiar water vascular system of coelomic origin with podia or tube-feet projecting out of the body. Although all living echinoderms have a pentamerous (five-part) radial symmetry, an internal skeleton, and a water-vascular system derived from the coelom (central cavity), their general appearance ranges from that of the stemmed, flowerlike sea lilies, to the wormlike, burrowing sea cucumbers, to the heavily armoured intertidal starfish or sea urchin. Moderately strong to weakly tide-swept, circalittoral bedrock and boulders appears to be an advantage to the system. body derived from three embryonic germ layers; ectoderm, mesoderm, and .
