Nocturnal Animals

Nocturnal animals are awake at night and sleep during the day. They have special features that help them see, hear, and move in the dark. Many animals choose the night to avoid the heat and stay safe from daytime predators.

How They See in the Dark

Nocturnal animals have special eyes that let in more light. Owls have very large eyes compared to their head. Cats have a mirror-like layer behind their eyes that reflects light. This is why a cat's eyes seem to glow in the dark.

Famous Nocturnal Animals
