They can also have very well developed senses of smell and hearing.These animals are usually appropriate for pet owners who stay up late, and are ready to provide for them then. Nocturnal predators usually have a sensitive sight and/or do not rely on visible light to see(infrared vision). Nocturnal animals are usually more vulnerable to predation, so keeping active only during the night makes them somewhat "invisible"(mice). Nocturnal means done or active during the night. Below is a diagram to show the times and duration of a twilight.
Being crepuscular serves them well as pets when their owners are rather busy during the day the owners are unavailable when the pet itself is inactive. When a prey population increases due to their crepuscular habit, predators will have more food thus increasing their population, which in turn decreases the prey, then the predators decrease, increasing the prey, and so on. This creates a state of a self regulating oscillating equilibrium. In addition to the that, in the wild, predators are generally least occurring during those times. On the other hand, crepuscular prey can use this light to easily spot and avoid predators(rabbits). Usually Crepuscular predators are active during twilight because their prey is active during that time, and they still have a decent amount of light to hunt and forage(guinea pigs). Twilight is the illumination of the earth's lower atmosphere when the sun itself is not directly visible. Crepuscular animals are active during twilight. Diurnal animals predominantly have colored and vivid vision.Ĭrepuscular means of Twilight. Diurnal prey have the advantage of easily spotting predators from a distance. Animals that mainly rely on vision to hunt for food are usually diurnal. However, in the wild, diurnal animals have the advantage of, sometimes, direct sun exposure( for example turtles which use it for vitamin D3 synthesis), and more importantly, a very good visibility. Pets are usually diurnal, which is generally great for them since mostly humans are also diurnal, so their carers will have time for them, at least partially during the day. Though times of activity of an animal are in relevance to the animal, as in it is to its advantage, it can act against it when this animal is a pet. Animals that are diurnal are active during the day.
Diurnal by definition means of or during the day.
