Echinoids are invertebrate marine animals that are found throughout the world. The group includes sea urchins and sand dollars. Echinoids exhibit pentaradial symmetry and have a skeleton, or test, of fused calcitic plates embedded in the skin. Tube-feet are used for feeding and respiration, and spines are involved in locomotion and defense against predators.Echinoids More...are useful in evolutionary studies, as they are non-chordate deuterostomes. They are more closely related to humans and other chordates than flies or nematodes, and regions of synteny between sea urchins and mammals have been identified. Sea urchins have been used extensively for studies of gene regulation during development and other aspects of embryology. Sea urchins also exhibit a wide range of genetic variation, both between species and within a species. Less...
