The term for an animal that is active during the day is "diurnal." Diurnal animals are adapted to behave and hunt primarily during daylight hours, often developing physiological and behavioral traits that aid their survival in a daytime environment. Examples of diurnal animals include humans, many birds, and certain primates. Diurnal species may rely on sunlight for foraging, navigation, and social interactions or to evade predators that are nocturnal or crepuscular (active during dusk and dawn). The study of their behaviors and habitats can provide insights into ecological relationships and adaptations.
