Look at these amazing pictures of alligators at night. Their eyes glow bright red.
Although you may think the images have been photoshoped, you are wrong!
Here’s why alligators’ eyes are glowing bright red in the dark:
Like cats, an alligator has a tapetum lucidum at the back of each eye.
This structure reflects light back into the photoreceptor cells to make the most of low light.
The colour of eyeshine differs from species to species.
In alligators, it glows red… And that’s a really good way to locate alligators on a dark night.
And I bet this is what they are currently doing in Mexico after Eta… Looking for crocodiles’ eyes around.
