Photo showing the hinge that joins the cephalothorax and opisthosoma.

This is an image showing the hinge a cartilage type material that holds the two parts of the shell (the cephalothorax (prosoma) and opisthosoma (abdomen)) together and acts like a hinge. This part is shed when the horseshoe crab molts. .
