	Pseudocentrotus Depressus ''Pseudocentrotus depressus'', commonly known as the pink sea urchin, is a species of sea urchin, one of only two species in the genus ''Pseudocentrotus''. It was first described in 1864 by the American marine zoologist Alexander Agassiz as ''Toxocidaris depressus'', having been collected during the North Pacific Exploring and Surveying Expedition undertaken by Captain Cadwalader Ringgold and later Captain John Rodgers. Description This sea urchin is distinctive in its shape, with the oral (lower) surface being flat and the aboral (upper) surface markedly depressed in the centre. The tubercles are numerous and even in size, and the spines are fine and short, their diameter being about a quarter of their length. The inter-ambulacral plates are broad and the pore pairs are arranged in slightly curved groups of six or seven pairs. Ecology As is the case with most other sea urchins, the sexes are separate in this species, and adults liberate eggs and sperm into the water column ...

picture info	Echinoderm An echinoderm () is any member of the phylum Echinodermata (). The adults are recognisable by their (usually five-point) radial symmetry, and include starfish, brittle stars, sea urchins, sand dollars, and sea cucumbers, as well as the sea lilies or "stone lilies". Adult echinoderms are found on the sea bed at every ocean depth, from the intertidal zone to the abyssal zone. The phylum contains about 7,000 living species, making it the second-largest grouping of deuterostomes, after the chordates. Echinoderms are the largest entirely marine phylum. The first definitive echinoderms appeared near the start of the Cambrian. The echinoderms are important both ecologically and geologically. Ecologically, there are few other groupings so abundant in the biotic desert of the deep sea, as well as shallower oceans. Most echinoderms are able to reproduce asexually and regenerate tissue, organs, and limbs; in some cases, they can undergo complete regeneration from a single limb. ...
