Purple Sea Star

Hi beautiful starfish there. Sea stars are invertebrates, members of a grouping (phylum) called Echinodermata along with brittle stars, sea cucumbers, sea urchins, sand dollars and others. I will move it from fish to the "other" category. Again, nice shot.

It may be the subspecies depending on where in California you found it. "Pisaster ochraceus can be found from Prince William Sound in Alaska to Point Sal in Santa Barbara Co., California. Pisaster found within the warmer waters from Santa Barbara County to Baja, California is Pisaster ochraceus segnis, a subspecies of Pisaster ochraceus [7]"--Wikipedia
