What is the term for animals that are active during the day?

Animals that are active during the day are referred to as diurnal. These animals have adapted to rely on the sun's light for their daily activities, such as foraging, hunting, and social interactions. Examples of diurnal animals include most bird species, primates, and herbivorous mammals like elephants and deer. In contrast, nocturnal animals are active at night, and crepuscular animals are most active during the twilight periods of dawn and dusk. Diurnal behavior is advantageous for animals that rely on sight for capturing prey or avoiding predators.
