Hemigrapsus nudus

Purple shore crab:

Purple shore crab (Hemigraspus nudus): Hemigrapsus nudus is the most common high intertidal crab. It is differentiated, no matter what the color variation, by the purple spots on its claws. It is especially common in back bays, stream mouths, and any place with gravel and rockweed Fucus. Not only is the purple shore crab (as it's usually called) ubiquitous, but its molts are abundant at the high tide line, especially around July. This is usually the first crab that small children, tourists and brown bears find by turning rocks over at low tide, and outings at the beach wouldn't be quite the same without it.
