The Eye of the Tiger Shark

One notable aspect of the Tiger Shark's eyes is their placement, contributing to a unique visual perspective. The lateral positioning of the shark's eyes creates a binocular overlap, enhancing depth perception in the horizontal plane. This adaptation is crucial for accurately assessing distances and sizing up potential prey or threats. The pupils of Tiger Shark (Galeocerdo cuvier) eyes can adjust to different lighting conditions, expanding or contracting to control the amount of light entering the eye. This ability is particularly useful as the shark moves between different ocean depths and lighting environments during its hunting and exploratory activities. Most Sharks can't distinguish colors, but some species, like Tiger Sharks, have a reflective layer behind the retina, the tapetum lucidum (as cats). The light received inside the ocular globe is reflected on the retina, enhancing vision in low-light conditions. It sees 10 times better than humans in dim light. This photo was taken with a macro lens because as wild animals, Tiger Sharks don’t get so close to the camera, and I was aiming for the eye beautiful details.
