During the night, when most of us are asleep, many animals are active thanks to their ability to see in the dark. The species that sleep during the day and become active at night are called nocturnal animals. The NatGeoWILD video below briefly introduces us to some of these animals.
Some species, such as tarsiers, have large eyes that can absorb more light, which help them see at night. Their eyes are fixed so they have to turn head in order to see around. The same goes for owls, which can cover a 270-degree angle by turning their head.
It’s not just the birds that are great at night vision. Cephalopods, cats, crocodiles, they have all evolved over time and can now see pretty well in the dark.
