Green Shore Crab:
Green Shore Crab (Hemigrapsus oregonensis): This very common crab looks somewhat like the Purple shore crab (Hemigrapsus nudus), except that it often lives lower in the intertidal area and in calmer spots, is generally somewhat smaller, and is usually greenish as opposed to purplish, without purple spots on the claws.

For positive identification, such as of strange color variants or bleached molts, look at the legs: those of Purple shore crab (Hemigrapsus nudus) are distinctly less hairy, if they have any hair at all.
