Blood Star


The blood star gets its name from its bright red color, but can also be yellow or tan. 

A smaller star, it does not grow more than about 6 – 8 inches across. Look for the slender arms (rays) with a smallish central disk in the middle. 

Find blood stars around rocks covered with growth like sponges, which they eat.  

Because they are found lower in the intertidal zone, it has to be a good low tide to see them.


The armpit blood star is a distinct species.
