There are distinct shapes for each the male and female dungeness crab on the underside (abdominal) of the body and it takes up about half of the underside. The male's looks more elongated (triangular) and the female's is wider in shape. Check out the Oregon Department of Fish and Wildlife web site for more info including videos of how to crab. Here's a link (copy and paste it into your browser's address bar) to a flier for more details: http://www.dfw.state.or.us/resources/fishing/docs/CrabbingFlyer.pdf
The males has one larger set of hind legs in comparison to the female crabs. Also the males have more distinct colorful markings to attract mates.
SORRY - THE ABOVE ANSWER IN INCORRECT. Here is the correct information:
The legs are the same size in the male and female Blue Crab. Female Blue Crabs have "painted fingernails" or red-tipped claws while the male has blue claws.
Another way to tell the difference between the male and female Blue Crabs is by the apron on the underside of the crab.
- Males have aprons shaped like the Washington Monument and they are known as a "Jimmy".
- Immature females have an apron shaped like an inverted triangle and are known as a "Sally" or a "She-Crab". (Personal Note: please, never harvest immature female crabs so they can continue to reproduce.
- Mature females have an apron shaped like the White House and are known as "Sooks".
(Personal Note: Please don't take any female crabs in harvest. Sooks can hold on to the male sperm for a long time before fertilizing her eggs and spawning. They sometimes travel from brackish water to higher salinity before spawning. Thanks!)
Males are Jimmies and females are Sally or she crab for immature crabs and Sook for a mature female.
the female keep the eggs until they hatch
yes she soes have the blue crabs
Blue crabs, like lady crabs, are definitely swimming crabs. The largest population of the blue crab can be found in the Chesapeake Bay.

The difference between the green and blue kyanite is their colors.
what is the difference between honeybee and blue Jay
The most obvious way to determine whether a kookaburra is male or female is that the male has blue wing-tips and a deeper blue on his tail. Females tend to be stockier and more heavyset, but this is not an obvious difference.

No, there is no difference.
The males are somewhat larger than the females, but there is very little difference between the sexes in external appearance, at any age. (Audubon)
