Echinoderm: Applications, Anatomy and physiology & Mode of life

An echinoderm (/ɪˈkaɪnəˌdɜːrm, ˈɛkə-/) is any animal of the phylum Echinodermata (/ɪˌkaɪnoʊˈdɜːrmətə/), which includes starfish, brittle stars, sea urchins, sand dollars and sea cucumbers, as well as the sessile sea lilies or "stone lilies". While bilaterally symmetrical as larvae, as adults echinoderms are recognisable by their usually five-pointed…
