A Strongylocentrotus Purpuratus is a sea urchin that inhabits the Pacific Ocean.
- AKA: Pacific Purple Urchin.
- Context:
- It can (often) be found along the Pacific Coast.
- It can (often) reach Sexual Maturity at around two years of age.
- It can (often) reproduce in the winter months of January through March.
- ...
- It can range from inhabiting intertidal zones to living in nearshore sub-tidal environments.
- ...
- It can serve as a Model Organism in developmental biology and genomics research, providing insights into evolutionary biology.
- It can live up to 70 years and typically grows to about 10 cm in diameter.
- It can have deep purple coloring and orange eggs.
- ...
- Example(s):
- one found fossilized along Laguna Beach in California, providing evidence of long-term habitation in this region.
- one found fossilized in the Pacific Northwest, dating from the late Cretaceous period (which indicates their precense over 66 million years ago).
- one found in Baja California, dating back 2.5 million years (Pleistocene fossils).
- ...
- Counter-Example(s):
- Red Sea Urchins, which have a larger size, red coloration, and different habitat preferences.
- Mesocentrotus Nudus (naked sea urchin).

- Strongylocentrotus purpuratus is a species of sea urchin in the family Strongylocentrotidae commonly known as the purple sea urchin. It lives along the eastern edge of the Pacific Ocean extending from Ensenada, Mexico, to British Columbia, Canada. [1] 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. [2] Strongylocentrotus purpuratus is used as a model organism and its genome was the first echinoderm genome to be sequenced.
