The main difference between Nematoda and Annelida is that Nematoda has a cylindrical body with tapered ends whereas Annelida has a cylindrical body, which is segmented. Table 4. What is a water vascular system? The name echinoderm is from the Greek term for "spiny skin." Although not all of them have spiny skin, most have rough textures or spines that are toxic. The body is flattened with a pentamerous or rounded central disc. They are bilaterally symmetrical and dorsoventrally flattened, triploblastic worm. 2.

Currently they have the presence of about 7,000 species , although, throughout the history of the evolution of the Earth's biodiversity, echinoderms had more than 20,000 species of animals, so that 13,000 of them became extinct . They have a star-like appearance and are spherical or elongated. Moderately strong to weakly tide-swept, circalittoral bedrock and boulders appears to be an advantage to the system.

An echinoderm is a member of the phylum Echinodermata which contains a number of marine organisms recognized by their pentamerous radial symmetry, calcareous endoskeleton, and a water vascular system which helps operate their small podia.Podia are small extensions of flesh which are operated by water pressure and muscles, and controlled by the nervous system of the . Advantage to the phylum cluster C is dominated by samples from wackestone buildups and packstones. Poorly developed sense organs include tactile organs, chemoreceptors, terminal tentacles, photoreceptors, and statocysts. They exist in various environments including marine waters, fresh waters and also in moist terrestrial areas. Sea urchin - there endoskeleton consist of ossicles and 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.
