Question

phylun echodermeta?​

Answer 1

Echinoderms are animals that you must be knowing. If you know a starfish, then you are well aware of what an echinoderm is. Echinoderms are animals that are invertebrates. The name actually means spiny skin! All the animals in this phylum exhibit spiny skin and hence are grouped together. 

Answer 2

Echinoderm is the common name given to any member of the phylum Echinodermata of marine animals. The adults are recognizable by their (usually five-point) radial symmetry, and include such well-known animals as sea stars, sea urchins, sand dollars, and sea cucumbers, as well as the sea lilies or "stone lilies".

Echinoderms are found at every ocean depth, from the intertidal zone to the abyssal zone. The phylum contains about 7000 living species,making it the second-largest grouping of deuterostomes (a superphylum), after the chordates (which include the vertebrates, such as birds, fishes, mammals, and reptiles). Echinoderms are also the largest phylum that has no freshwater or terrestrial (land-based) representatives.
