Why are some animals nocturnal?

Browse → Animals → Pets

It’s the middle of the night and you’re in bed, sound asleep. Outside though, there’s a whole world of activity! Some animals’ days only begin when the Sun goes down.

There are a few really good reasons for this. If all animals were active during the daylight, the world would be a lot more crowded. With some of the animals taking the night shift, there is less competition for food, water, and space.

The nightlife also helps some animals escape predators that would hunt them during the day. Some predators, like owls and wolves, have adapted to nighttime hunting, so animals are not totally safe.

In very hot parts of the world, a nocturnal life makes sense because it’s much cooler at night than it is when the Sun is shining. Most animals don’t have air conditioning like people do, so avoiding the Sun really helps.

There are a lot of nocturnal animals. Some common ones that you probably know of are cats, badgers, bats, cockroaches, fireflies, hamsters, owls, raccoons, tarantulas, wolves, and opossums.

    Night and Day

    If we didn’t have inventions like candles, lamps, and flashlights, people would have a pretty difficult time being active at night. We rely on our eyes a lot, and our eyes need light to work well.

    Close your eyes for a moment and think about what senses you could use to navigate in the dark if you had to. Could you find your food by smelling it? Could you tell if someone was nearby by listening?

    Many nocturnal animals have senses that are specially developed for nighttime. Some even have senses that people don’t have. Some snakes can see body heat, and bats can hunt by using echolocation. They let out a high-pitched noise and listen to the echoes that bounce off objects. What would life be like if you had those abilities?
