The term for animals that are active during the night is "nocturnal." Nocturnal creatures are adapted to thrive in the dark, utilizing heightened senses such as enhanced vision or acute hearing to navigate and hunt. Many nocturnal animals, like owls, bats, and certain rodents, have specific adaptations that help them detect prey and avoid predators in low-light conditions. Being nocturnal can also be a strategy to avoid competition with diurnal animals that are active during the day. The diversity in behaviors and adaptations in nocturnal species showcases how organisms evolve to survive in various ecological niches.
