Nocturnal animals are animals that are mainly active during the night. They hunt or feed during the night, and sleep during the day.
They become more active at night to hunt or avoid heat and predators. Nocturnal animals have special characteristics that
let them roam in the dark more effectively. The eyes get bigger and the pupils widen. This helps them to collect more light.
Animals like owls and large cats have special hearing to hunt at night. A cat can move its ears to help him hear better. Some animals, like snakes, use taste to navigate and locate prey.
Some animals, like bats, use echolocation to find food. Bats release a high-pitched sound that bounces off objects, including prey. The echoes tell the bat how far away the objects and prey are.
