Sand Dollar Dendraster excentricus

By Harbor WildWatch September 11, 2021

Sand dollars are thriving at the Purdy Sand Spit, despite some die-off during this summer’s heat. These incredibly resilient animals are uncovered by the low tide twice a day. While the tide is low and they are exposed, they often bury under the sand which prevents desiccation (drying out) and helps keep them from being trampled. When the water returns, they can move about on the surface of the sand, and sometimes you can witness the trails they make in the sand as they slowly travel.
