Blue Crab
(Callinectes sapidus)
The Blue Crab is commonly found in either the most saltiest water or freshest waters of the Western Atlantic Ocean. They are in the domain Eukarya, kingdom Animalia, and phylum Arthropoda. This species is also found in the class Malacostraca, order Decapoda, and family Portunidae. They are also in the genus Callinectes and species sapidus. This organism has bilateral symmetry meaning that you are able to draw a line down the middle of the organism and the two side would be a mirror reflection of each other. They have two red claws, two blue “paddle” legs, four other legs, a white stomach, and one olive colored pointy shell. A structural adaptation this species has is weighing one to two pounds to be able to swim better. Another structural adaptation this species has is its large claws to be able to grab onto things much better. Another structural adaptation this animal has is lots of legs to be able to walk faster and better across the ground. Did you know that once they grow out of their shell, they mold a new one? The predators of this organism are humans, sea turtles, the red drum fish, herons, and that atlantic croaker. The prey of this organism are clams, oysters, and mussels. They are also heterotrophic meaning that they get energy off of other plants and animals. They are also ectothermic, or commonly put to words as cold-blooded or change body temperature according to its environment.
