For that reason, we have compiled a brief list of facts that you can use to impress your friends at the next crab feast! Keep reading and discover a few interesting facts about crabs that you may not have known.

Color Of Their Shells

Many people are confused about why blue crabs are not blue when they are cooked. The reason for that is because there is a pigment inside those shells that give them that blue color. However, when they are placed in hot water, that pigment is broken down, and they turn red.

Many Types Of Crabs

Most people are only familiar with two or three types of crabs. There are approximately 5,000 types of crabs on earth today.

Females Only Mate Once

Did you know that female blue crabs only mate once in their entire life? Most people are under the assumption that because they have so many babies, they mate multiple times; however, that is not the case.

A Group Of Crabs

Most people are familiar with the term bushel. It is used to describe the number of crabs that people use to order. However, the term for a group of crabs is a cast. This term is used when the crabs are alive in the water and are congregating.

The Scientific Name

If you are a science buff, you will probably appreciate this one. The blue crab’s scientific name is Callinectes sapidus. When this is translated from the Latin language, it means beautiful savory swimmer.
