Estrella de bradley observada en la Ensenada El Embudo, en la Isla Espíritu Santo.
Here is one of only three Pisaster ochraceus or Purple (aka Ochre) Stars I found today, in an area that used to have hundreds prior to the outbreak of Sea Star Wasting Syndrome.

This tiny, pale 1" Leptasterias hexactis or Colorful Six-armed Star, aka Six-rayed Star, was found when I turned over a rock at low tide. Apart from three Pisaster ochraceus, it was the only sea star I found today on this beach.
Was out of the water for quite some time. It was still alive however.
