The term for an animal that is active at night is "nocturnal." Nocturnal animals have adaptations that enable them to thrive in low-light conditions, such as enhanced night vision, acute hearing, and heightened sense of smell. This evolutionary strategy allows them to avoid daytime predators, find food, and engage in social behaviors during the night. Examples of nocturnal animals include owls, bats, raccoons, and cats. Many nocturnal species have unique behaviors, such as hunting and mating, that are specifically adapted to their nighttime activity patterns, highlighting the diversity of life in various ecosystems.
