The horseshoe crab (also known as the king crab), is a hard-shelled invertebrate found on the sea floor in warmer climates. Despite it's name, the horseshoe crab is not actually a crab (or crustacean) and is in fact more closely related to arachnids such as spiders and scorpions.he horseshoe crab has a hard outer shell, five pairs of legs and a long, thin tail which the horseshoe crab uses for changing direction whilst swimming rather than as a defensive weapon.
