Nocturnality refers to the behavior of certain animals that are active during the night and rest during the day. This adaptation allows them to avoid predators and take advantage of cooler temperatures. Common nocturnal animals include owls, bats, and raccoons, which have developed specialized senses to navigate and hunt in low-light conditions. Nocturnal creatures often have enhanced vision, such as tapetum lucidum, a reflective layer behind the retina that improves night vision. Their activity patterns can also influence ecosystems, as they play crucial roles in pollination and seed dispersal during nighttime hours, contributing to the balance of their habitats.
