Our son and his girfriend, Jeanie, flew to Seattle on Thursday night and the next day we drove to Anacortes, WA. We met the ferry and Jeanie's parents in Anacortes. While we waited for the ferry the tide was dropping, so we entertained ourselves looking at the little crabs that scuttled out from under the rocks. Crabs are scavengers, they hunt for food on the beach. They in turn, are also eaten by other animals.
