Growing into their eyes

Description

A young Great white shark curious about what our researchers are doing. How do we know this was a young shark? Having a look at their eyes is a good indication of age when it comes to Great white sharks. Their eyes don’t change much in size throughout their lifetime and when we compare their eye size to their body size, we can get a relatively good idea. The bigger the eye in comparison to their body, the younger the shark is and ultimately, they grow into their eyes. Also, white sharks’ eyes are far from being “black and lifeless” as described in the movie Jaws. They have dark blue pupils that are lively moving to investigate their surroundings.
