Stereoscopic is three-dimensional vision which is how we see. Sharks can see in both stereoscopic and monocular vision. We’ve already established that their eyesight is far superior to ours in dim light, but they can even change their field of vision whenever they want. The 8 Best Children’s Books About Sharks Available TodayĪlthough it’s been thought that sharks don’t have the best eyesight (especially considering that they sometimes mistake us for seals), they actually do have pretty good eyesight in certain circumstances. Do Sharks have Good Eyesight? Sharks can see ten times better than us in dim light This is the reason why both cats and sharks eyes appear to glow in the dark. Incredibly, cats also have this tapetum lucidum too. This is a major advantage to sharks as there is very little light in the ocean the deeper it gets. In fact, they can see approximately ten times better than we can in murky, dark, and clear water. This means that the light is available to the retina twice and increases visibility in areas that have poor light. Light goes through the retina, hits the crystals, and is then reflected back onto the retina. Tapetum lucidum is a layer of mirrored crystals that is located just behind the retina. Sharks also have a unique feature that allows them to see well in dark or murky water. Incredibly, the amount of rods and cones differs between species, so some sharks can see better than others. However, recent studies have shown that they are actually able to see in color, but it is not known to what extent. For a long time it was thought that sharks lacked the necessary cells to see color. Rods and cones are the photoreceptor cells that determine light and dark (rods) and color (cones). However, sharks have duplex retinas that contain both rods and cones. 34,882 People Couldn't Ace This Quiz Think You Can? Take Our Brand New A-Z-Animals Sharks Quiz
