The term for animals that are active in the evening is nocturnal. Nocturnal animals have adapted to being active during the night, which often helps them avoid predators and reduces competition for resources. These animals have specialized adaptations, such as enhanced night vision, acute hearing, and heightened senses, to facilitate their activities in low-light conditions. Examples of nocturnal animals include owls, bats, raccoons, and many species of rodents. Their activity patterns play a critical role in ecosystems, including predation, scavenging, and pollination, and contribute to the overall balance of biodiversity.
