Some sharks have a clear membrane that covers and protects the eye when a shark bites its prey. Why do white sharks roll back their eyes?Īlso unlike humans, shark eyelids serve to protect the eye when attacking prey. Such an adaptation enables sharks to see even in low light and dark murky water up to 10 times greater than humans. Light is defused, acuity reduced and sensitivity increased. This provides for light to be detected a second time. Unlike humans are sharks' eyes equipped with a layer of mirrored crystals behind the retina. Individual sharks not only look very different, but they also seem to have different personalities too Sharks and rays belong to the class of fish with skeletons composed of cartilage, not bone. It also makes them the most feared creatures of the sea, to both sailors and sea inhabitants alike. They are powerful enough to launch their 2 -tonne bodies out of the water and are the ocean's apex predators which make them therefore much less abundant than other large sharks. #helpsavesharks #savesharks #shark #greatwhiteshark #sharks #oceanramseyandgreatwhite #oceanramseygreatwhite PHOTO BY #JUANSHARKS #Sharkphotographer #Sharkarma #savetheocean #instagood Join me at my team to learn about sharks OneOceanDiving.Great White Sharks are the world's largest predatory fish, reaching up to 6 meters in length.
