Horseshoe crab (Limulus polyphemus), on the western shore of the Chesapeake Bay at Fort Monroe National Monument, Hampton, Virginia.
Etymology note: What a puzzle! Polyphemus was the name of a Cyclops with a bit part in the Odyssey. The name translates many voiced, and might literally mean often spoken of, hence famous. It seems an odd choice, to name a creature with ten eyes after a creature with only one.
