Men have actually blue claws, and, similar to humans, feminine blue crabs “paint their fingernails” (i.e., the guidelines of these claws are “painted” red!)
As well as the claws, there are various other (better) how to figure out the sex of the blue crab. But first, a small technology.
The Atlantic blue crab (Callinectes sapidus) is an associate associated with the Brachyura – an order of crustaceans having a lower abdomen, or “apron,” folded against the ventral area (or stomach) associated with animal. a effortless method to consider this concept will be produce a crab away from a lobster.

This will help illustrate what sort of crab developed to its present type.
