The Atlantic horseshoe crab is a marine arthropod found along the North American Atlantic coast. Despite its name, it is not a true crab. It has a hard, domed shell and a long, pointed tail. Feeding on worms and mollusks, it inhabits shallow coastal waters. Typically, it measures 8-10 inches and weighs 3-4 pounds, often seen in large spawning aggregations. This summary is AI generated
