Adopt a Horseshoe Crab

Horseshoe crabs have remained relatively unchanged in appearance for 350 million years. The horseshoe crab is not actually a true crab, but a member of an ancient group of arthropods, closely related to spiders and scorpions. They have several pairs of eyes. The two large eyes on the head are sensitive to polarized light and can magnify sunlight 10 times. There is also a pair of simple eyes on the forward side of the head that can sense ultraviolet light from the moon and additional multiple eye spots under the head and underside of the tail. Survival of the horseshoe crab is threatened by human and beach development which can adversely affect their spawning activities. Adopt a horseshoe crab today!
