The term used for an animal that is active at night is "nocturnal." Nocturnal animals have evolved various adaptations that help them thrive in low light conditions. These adaptations can include enhanced senses, such as night vision, acute hearing, and a keen sense of smell. Examples of nocturnal animals include owls, bats, raccoons, and some species of rodents. Being active at night allows these animals to avoid predators, reduce competition for food, and take advantage of different ecological niches.
