Blue crabs are considered good swimmers and swim through the water with the help of the fifth pair of paddle-like legs. These paddle-like legs help them to swim more quickly and easily.

Like other crabs, blue crabs have claws, bright red for female blue crabs. Female blue crabs are slightly smaller than male blue crabs. A large male may be up to seven inches in size.


Blue crabs have a life duration of about three to four years. During this duration, they mate mostly from May to October, and females produce a lot of new crabs. All crabs cannot survive from infancy to the larval stage because of predators and other environmental factors. But thousands remain alive to repeat the reproduction cycle.

Blue crab Mating:

Blue crabs mate in low moderate salinity water, occurring once in a lifetime for female crabs. Mating takes place when the female is soft. Sperms are transferred into the female’s body which fertilizes her eggs. After mating, the male crab protects the female until the shell hardens.

Spawning takes place during spring and summer on nearshore seawater. When the eggs are extracted, they are fertilized and fixed to the pleopods in the female’s abdomen. The female transfers eggs under the abdomen until they are hatched.

Female moves toward the seawater. Hatching occurs in the nearshore area where larvae develop into zoea, transfer into megalopa, and start a new cycle.

Young crabs move towards low salinity water and grow rapidly. They attain their full size in one to two years.


Blue crabs live in estuarine habitats throughout their life cycle. In the larval stage, they live in the oceans.

Young crabs live in shallow intertidal habitats and on the south Carolina coast. 

While the mature crabs preferred deeper water to live in.


Blue crabs eat everything easily available. Crabs mostly eat calms, small crustaceans, the residue of plants and animals, insects, mussels, dead fish, and worms. They can also feed on dead animals. 

In addition, they play a vital role in decreasing other harmful species. Blue crabs need a varied diet to keep balance in their environment.
