     The horseshoe crab got its name because its shell is shaped like a horseshoe. In the past a horseshoe crab has been called pan crab, saucepan crab, swordtail crab, king crab, and piggyback crab. The Indians called horseshoe crabs Se-eanauk because horseshoe crabs have long pointy tails like spears. The Indians thought that horseshoe crabs were fish.  In 1588 Thomas Hariot, a British naturalist who visited America, described the horseshoe crab as the horsefoot crab. Other explorers from Europe said they saw a "sword-tailed beast" and called it "King Crabb". 
      The scientific name of the horseshoe crab that lives in North America is Limulus polyphemus. It is named after a one-eyed giant in Greek mythology named Pholyphemus . The word limulus means a sideway glance in Latin.
