Atlantic Horseshoe Crab (Limulus polyphemus)
This “living fossil” is one of Earth’s oldest species–even older than the dinosaurs! Despite their common name, horseshoe crabs are not crabs, but are more closely related to arachnids like spiders, scorpions, ticks and mites. During the spring and summer, they migrate in large numbers towards sandy beaches and congregate in the shallow water to breed. Their eggs provide a valuable source of food for many species including our coast’s threatened red knots.
