Gar Brain

Caption

Behold, the gar's brain. In this microscope image, the brain's left hemisphere fluoresces green and the right glows magenta. Yet, at the bottom of the image, nerves of both colors can be seen connecting to both hemispheres. This shows that both of the gar's eyes are connected to both sides of its brain, like a human's eyes are.
