The California purple sea urchin, Strongylocentrotus purpuratus, lives along the eastern edge of the Pacific Ocean extending from Punta Banda, Mexico to British Columbia, Canada.[1] This sea urchin is deep purple in color and live in lower intertidal and nearshore subtidal communities. Along with sea otters and abalones, it is a the prominent member of the spectacular kelp forests community.[2] It normally grows to a diameter of about 4 inches and it may live as long as 70 years[3].
The purple sea urchin plays many roles[4]. Besides its ecological importance, it is also an important fishery along the west coast of the US[5] and it is one of several biomedical research models in cell and developmental biology.[1]
Because of its importance to biomedical research, the sea urchin genome sequence was read and annotated in 2006.[6] The sea urchin genome is estimated to encode about 23,300 genes. Many of these genes were previously though to be vertebrate innovations or were only known from groups outside the deuterostomes. Thus the sea urchin genome provides a comparison to our own and those of other deuterostomes, the larger group to which both echinoderms and humans belong.[6] Using the strictest measure, the purple sea urchin and humans share 7,700 genes.[7] Many of these are genes involved in sensing the environment[8] which is surprising for an animal with no head!.
