Pseudoscorpions

I found these little creatures under a piece of driftwood on a California beach a few years ago. They are pseudoscorpions, an order of arachnids that resemble miniature scorpions - minus the tail, hence the name. They are very tiny (only a few millimeters long) and thus are rarely noticed, but there are thousands of species, and they can be found throughout the world. They eat other small arthropods. Like scorpions, the mothers carry their tiny babies on their backs after they hatch.
