Deer eyes have a reflective layer that makes them shine in the dark when light hits them

Cats have more rods and cones than humans, enabling them to see with much less light

Unique cells in frogs' retinas enable excellent night vision

Cockroaches see without light by slowly absorbing it instead of reflecting it

Owls' large eyes allow them to capture fish, reptiles, insects, spiders, mice, and other small mammals

A layer in red foxes' eyes reflects light back, doubling their vision capability
