Crab Crisis, Valuable Horseshoe Species Going Extinct

Commonly found living in warm, shallow coastal waters on the sea floor, horseshoe crabs play an important ecological role. A continuing decrease in their population will affect other species, especially shorebirds that feed on the eggs, destabilizing the food chain. Sea turtles also feed on adult horseshoe crabs.
Scientists worldwide want to include the invertebrate in schedule IV of the Wildlife Protection Act of 1974, labeling them as an endangered species. Enforcement will include monitoring for improper uses of horseshoe crabs.
