How do you know the difference between a male and female blue crab?

You must be brave enough to pinch the body of the blue crab from behind and lift it upside down (It hurts a lot if they pinch you!).

Male blue crabs have a distinct shape like a pencil – or the Washington Monument – in the center of their bellies. Female blue crabs, on the other hand, have a shape like the Capitol.




  1. another easy way to distinguish the sex of a crab is the claw tips. females have red tipped claws whereas the males, are blue.
