Atlantic Horseshoe Crab

The body of a horseshoe crab is divided into three parts: the prosoma, opisthosoma and telson, or tail. The prosoma is the front, semicircular part and the opisthosoma, which protects the gills, is attached to the prosoma with a hinge. The top of the shell has ridges and spines. Seven pairs of leg-like appendages are found under the shell.
