You may have heard that if a blue crab has red claws it is a female and if its claws are blue it is a male. Think of girls with red nail polish. This is not necessarily true. Although females do tend to have more red on their claws than males, this technique doesn’t always work. Take this guy for example. When you turn him over, you can clearly see the shape of its apron looks like the Washington monument in Washing D.C. A Female’s apron is shaped like the Capital building.
