The Horseshoe crab's scientific name is the Limulus Polyphemus. This  crab  lives in muddy bottoms of shallow water and sandy ocean floors(mainly by the Atlantic Ocean) . It is also found in  near the Gulf of Mexico.  Horseshoe crabs eggs play an important role in the ecosystem.  Because they are a source of food for many other fish. They come to the top of the sea and other fish eat them. The crab eats

Worms (it's their favorite food), molluscs, crustaceans, and small clams. Crush hard foods with their legs and then pass all the food to their mouths.
