Crab Has Eyes. A comprehensive look at horseshoe crab anatomy. Crabs have two compound eyes located on the ends of stalks. Located on short moveable stalks, crabs can adjust their eyes and tuck them into their eye sockets for protection. Crabs combine the input from their two eyes early on in their brain's visual pathway to track a moving object, finds new research. On the underside of the crab, there are two ventral eyes, located near the mouth, which may help orient the animal when swimming. As seen in the diagram below, they are located on mobile stalks known as peduncles. Crabs have compound eyes, which means their eye is formed of hundreds thousands of individual light sensors with their own lens and cornea. Even though they can't focus well, their eyes are very sensitive and can easily detect uv light in low light conditions and pick up on the slightest movements around them. Although a crab's two primary eyes found on independently moving eye stalks are compound in nature, primitive simple eyes around his body. The eyes are particularly sensitive to movement and can detect even the slightest motion in their environment. Crabs don’t see a single image, instead they get a mosaic of repeated, blurry pictures. They allow a wide range of movement and a panoramic view. These eyes are made up of thousands of tiny lenses that allow the crab to see in many directions at once. Eyestalks can move in different directions and allow a crab to see all around. They have compound eyes with panoramic visions.
