seaurchin

Seaurchin are enterocoelous coelomates with a pentaradiate form and no definite head or brain. Echinoderms can be readily differentiated from other groups of organisms through unique physical and morphological attributes that include: 1) possession of a calcified spiny endoskeleton - made of five tight fitting plates 2) a water vascular system for nutrient uptake, gas exchange and movement 3) dermal brachiae and 4) a rigid spine or pedicellariae bearing plate.
