Summary ²

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.
