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. These are formed from calcite, a mineral made of calcium carbonate. The next characteristic of echinoderms is to move with ambulacral, namely the tubular legs with small holes that serve to suck.
