The eye is large in size and elliptical body. Many sharks depend heavily on their vision whilst hunting although there are occasions where the eyes play little or no role at all such as when a hammerhead is searching for a stingray which is completely buried. The cornea is the clear, outer covering of the vertebrate eye. It is covered by three coats. These features are thought to be used as protection against abrasion, acting as a layer of armor.

The shark eye has a reflecting layer called a tapetum lucidum located behind the retina. They are located in the orbits and are laterally directed. SHARK EYE (SCOLIODON EYE) – ANATOMY   Shark two eyes are present on the head. However, this is the first case these structures have been observed on a creature's eyes. Yet sound is often the shark's first tip-off that prey is nearby. Because sound travels farther and faster underwater, sharks are easily able to detect their prey from distances of more than 800 feet (243 meters) [source: Each ampulla is composed of a cluster of sensory cells that ultimately enables sharks to detect prey that may be hiding in the sand, and even possibly notice changes in the water’s temperature, pressure, salinity, magnetic fields, and mechanical stimuli. Yup, you read that title correctly. … In the majority of species, the eyes are well developed, large, and complex structures. It is a hollow structure. Anatomy of a Shark Eye [To the Top] The outer layer of the shark eye comprises a thick cartilaginous sclera and a gently curving, transparent cornea, the fine structure of which includes sutural fibers that resist corneal swelling and loss of transparency in challenging chemical environments (Tolpin et al. Essentially the structure consists of a layer of parallel, plate-like cells filled with silver guanine crystals. The shark eye is essentially a hollow ball equipped with all the features one would expect in that a typical vertebrate: cornea, iris, lens, and retina. Two holes on either side of a shark's head might be the only clue you'd have to the presence of shark ears. A new study on whale sharks reveals the existence of tiny teeth-like structures covering the eyes. Eye of a Porbeagle Shark. Around a shark’s head is an entire sensory network called the ampullae of Lorenzini, a very unique part of the shark anatomy. According to a newly published study, whale sharks (Rhincodon typus) eyes are covered with dermal denticles, which is a novel mechanism of eye … The prey doesn't even have to be that close. The crystals reflect light that has already passed through the retina and redirects it back to restimulate the retina as it passes out through the eye. 1969).
