The scientific term for animals that are active at night is "nocturnal." Nocturnal animals have adapted their lifestyles, behaviors, and physical characteristics to thrive in low-light conditions. These adaptations can include enhanced night vision, acute senses of hearing and smell, and special methods of navigating the dark. Many nocturnal species, such as owls, bats, and some rodents, hunt or forage during the night to avoid competition and predators that are active during the day. Being nocturnal allows these animals to exploit resources and habitats that might be less accessible during daylight hours, contributing to their survival.
