- Large crab-like animal with a roughly horseshoe-shaped shell and a long, straight tail spine. The underside is equipped with numerous legs, with the male's hind legs modified for gripping onto females during mating.
- When the crabs spawn, they congregate on the beach in masses. The males find a female, and ride on top of them until they reach a spot to lay eggs in. The eggs provide an important source of nourishment for seabirds, alligators, sea turtles, and fish.
- This species is so adaptable, it can be found from the cold waters of Northern Canada to the tropical waters of Florida, the Caribbean, and the Yucatan peninsula.
