How do they know how different animals see?

How do we know animals can/can't see in color?

  • Answer:

    In the animal kingdom, sight is accomplished by using either rods or cones on the retina of the eye. Animals that see black and white and shades of gray have only the rods in their retina. Animals that see color have both rods and cones; the cones are for color, but require a lot more light to stimulate. The bottom line is that animals that see color are diurnal [daylight] and black and white vision is for nocturnal [night] vision. If an animal does not see color, it is adapted to night vision.

Seeing in colour is made possible by cell in our eyes called rod cells. Because animals do not have an abundance of these cells like we do, we can pretty safely assume that they cannot see colour the way we do.
