The entire body of the horseshoe crab is protected by a hard carapace. It has two compound lateral eyes, each composed of about 1, ommatidia, plus a pair of median eyes that are able to detect both visible light and ultraviolet light, a single endoparietal eye, and a pair of rudimentary lateral eyes on the top. The latter become functional just before the embryo hatches.
