This is a cute little tide pool crab that I photographed along the California coast. I’m not sure what type of crab it is, but they seem to have a wide range of slight shell pattern and color variations. This one is very small. The whole crab is about the size of your fingernail. They are really shy when you first come to a tidepool, but after a while they come out into the shallow water and are actually curious if you sit still for a while.
