Watch this to find out how humans and animals see the world differently
6 How sharks see
Sharks see extremely clear in water but cannot view color hence they see in black and white. Their clear vision under water and even in muddy water is due to the layer of mirrored crystals present behind the retina.
7 How fish see
Fish see in color unlike sharks but are restricted to red green and blue. Fish also have UV receptors to see infrared light while others are more adapted to polarized light.
