Like most pregnant moms, female crabs proudly show their expectant babies with a round, bulging belly.
The bulge on blue crabs, however, is found outside the body - in a mushy sac the size of a tennis ball, called a sponge. It changes color - yellow, when her millions of babies are just developing; orange, as they mature; black, when birth is near.
Virginia waters are loaded with sponge crabs during summer months, especially near Hampton Roads, a vital nursery for the entire Chesapeake Bay.
