Giant Ground Crab

The Giant Ground Crab is the largest terrestrial crab in the world, about two times bigger than the coconut crab, and is fully terrestrial, unlike most other crabs. It feeds on grass, nuts, seeds, insects, small reptiles, and small mammals. It is indigenous to Western USA areas, including California, Nevada, Arizona, New Mexico, Oregon, and Idaho. It lays its eggs underground where most predators won't eat their nutritious eggs, but since humans introduced domestic dogs to its area, this crab species is near threatened because dogs are known to dig out its eggs, leaving its eggs vulnerable to other predators (including other feral dogs).
