These two crab were just, um, minding their own business when they were rudely flipped over and inspected.

The crab at the bottom of this photo is male, the crab at top is female. Notice the difference in the shapes of their abdomens? Male crab have a longer, thinner abdomen; female crab have a shorter, rounder abdomen. They mate in the spring and summer. The process takes several days.
