Is my hermit crab a boy or girl?

The female land hermit crab has two openings on the under side of her third set of walking legs. If you have a crab that is willing to extend out of its shell far enough, you may be able to see the gonorpores. They are very small pinhole openings. Males do not have the openings. Female land hermit crabs also can have an egg sac on the side of their abdomen. This is hard to see also and can be confused with the molt sac.
