The Atlantic horseshoe crab (Limulus polyphemus), also known as the American horseshoe crab, is a species of marine and brackish chelicerate arthropod. Despite their name, horseshoe crabs are more closely related to spiders, ticks, and scorpions than to crabs. This species is found in the Gulf of Mexico and along the Atlantic coast of North America. A main area of annual migration is Delaware Bay.

For the crabs that do not have lungs, if the gills are kept moist, they can breathe just as well on land as they do in the water. This is why crabs like small, dark and moist hiding places when they venture onto land. Different types of crab have different gills and in different places, but they work in very similar ways.
