Answer Details
An animal that is active during the day is known as a "diurnal animal." "Diurnal" comes from the Latin word "diurnus," which means "pertaining to a day." These animals have adapted to being active during the daytime, and often have specialized sensory organs, such as eyes and ears, that are optimized for daylight conditions.
In contrast, "nocturnal animals" are active during the night, and often have adaptations to help them navigate and find food in low light conditions. "Terrestrial animals" are animals that live primarily on land, as opposed to aquatic or aerial animals. "Homoiothermic animals" are animals that can regulate their body temperature internally, maintaining a constant body temperature regardless of the temperature of the environment around them.
In summary, a diurnal animal is an animal that is active during the day, while nocturnal animals are active at night.
