Blue crabs start their lives as tiny zoea, floating in the ocean waters. While growing into the megalopa stage, the crabs drift back into the Chesapeake Bay, where they grow into juvenile crabs and, eventually, adults. The blue crab’s life cycle is also closely related to its migration patterns. Let’s take a closer look at the stages the life of the blue crab.
Female Crab MigrationMature female crabs migrate to the mouth of the Chesapeake Bay to develop a brood of eggs. Depending on the size of the female, female blue crabs carry and release 800,000 to 8,000,000 eggs.
