It takes a measure of faith to claim you captured a candid crab shot. Their senses, the ones they share with us anyhow, are acute. They have great vision and usually see us before we see them. This intimate scene looks candid.
Romaleon antennarium, the Pacific rock crab, has hairy legs and a creamy yellow underside with red spots. The heavy pinching claw is impressive. Its mid- to low intertidal seaweed surroundings include feather boa, back pine and some inscrutable red blades with which it blends beautifully.
