Sea urchins or urchins are small, spiny, globular animals which, with their close kin, such as sand dollars, constitute the class Echinoidea of the echinoderm phylum. They inhabit all oceans.
Generally, urchins have longer spines; sand dollars have shorter spines which give them a fuzzy appearance. Tube feet are a part of the water vascular system characteristic of all echinoderms. Pincers located between spines are called pedicellariae.
Echinoids are a group of free-moving echinoderms that includes sea urchins, heart urchins and sand dollars. Characteristic of echinoids are the projections that cover the test, called spines.
