It is a robust crab belonging to the family of swimming crabs (Portunidae) to which the familiar blue crab, Callinectes sapidus, also belongs.The carapace has four blunt frontal teeth and each anterolateral margin has nine similarly sized broad teeth. The chilipeds (claws) are robust with several well developed spines and the rear legs are flattened into swimming appendages as is typical of members of the portunid family. Individuals are grayish green to purple-brown and variable in color with small irregular white spots on the carapace and swimming legs (Motoh 1979, Perry 2007, GSMFC).
