People eat them. Although Blue Crabs are found along the Atlantic seacost from New England down to South America, they are shipped frozen to many other places which are not along the coast. Well, it isn't good at all. The female attaches 700 thousand to 2 million eggs to the underside of her abdomen. They drift for 40 days and continue growing and molting, to reach the crab stage.
Young crabs are about one inch wide.
In winter, Blue Crabs go to deeper water and bury themselves at the bottom. They are usually at a 45 degree angle, with only their eyes and antennae exposed. They stay there all winter. There are over four thousand kinds of crabs. Ghost Crabs are white and eerie when skidattling across white sand, like Pensacola Beach.
