Strongylocentrotus Purpuratus
''Strongylocentrotus purpuratus'', the purple sea urchin, lives along the eastern edge of the Pacific Ocean extending from Ensenada, Mexico, to British Columbia, Canada. This sea urchin species is deep purple in color, and lives in lower inter-tidal and nearshore sub-tidal communities. Its eggs are orange when secreted in water. January, February, and March function as the typical active reproductive months for the species. Sexual maturity is reached around two years. It normally grows to a diameter of about 10 cm (4 inches) and may live as long as 70 years. Role in biomedical research The initial discovery of three distinct eukaryotic DNA-dependent RNA polymerases was made using ''S. purpuratus'' as a model organism. While embryonic development is still a major part of the utilization of the sea urchin, studies on urchin's position as an evolutionary marvel have become increasingly frequent. Orthologs to human diseases have led scientists to investigate pot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
