A world checklist of Echinoidea, compiled by taxonomic experts and based on peer-reviewed literature. ... : Echinoids, or sea urchins (oursins [French], Seeigel [German], erizos de mar [Spanish]) constitute a group of exclusively marine invertebrates inhabiting the intertidal down to the deep-sea trenches. They are characterized by a globose or flattened skeleton known as a test. It is important to note that this is not a shell as in mollusks, because the test is mesodermally derived, and actually internal to the ectoderm, which in the form of epithelium covers the entire test and in fact the spines and other external appendages mounted upon it. The test is in turn made of stereom, the specialized manifestation of calcium carbonate endoskeleton unique to the echinoderms. The test comprises a corona, plus a peristomial region around the mouth, and a periproctal region around the anus. The corona also supports a variety of mobile appendages, including spines. Sea urchins come in a variety of different shapes representing adaptations to specific habitats and feeding strategies. Most readers will be familiar with the ... |
