Blue Crab
Callinectes sapidus
A blue crab is a crab with a muddy green top shell with hints of bright blue on its claw. Like every other animal they belong to the 8 groups of classification. Its domain is Eukarya, its kingdom is Animalia, its phylum is Arthropoda, its class is Malacostraca, its order is Decapoda, its family is Portunidae, its genus is Callinectes and its species is sapidus. You can find the blue crab in Cape Cod all the way to Uruguay. More specifically you can find the crab in habitats ranging from the saltiest water of the gulf to almost fresh water of the back bays. Especially common in estuaries, this species ranges into fresh water, and may be found offshore. A behavioral adaptation of the Blue Crab is it is aggressive when it is threatened. A structural adaptation of this organism is they have pincers so the blue crab can defend itself and grab things more easily. A functional adaptation is that the Blue Crab can go down more than 30 miles under the water. The Blue Crab eats mussels, clams,and oysters.. This means that the Crab is heterophic. It is threatened by the ed Drum Fish, Atlantic Croaker, herons, sea turtles, and humans. The blue crab is ectothermic and bilateral. This means that if you cut the Blue Crab in half and fold it, it would match up perfectly.
