Nocturnality is an animal behavior characterized by being active during the night and sleeping during the day. The opposite, diurnality, is associated with human lifestyle and most familiar animal species. The intermediate crepuscular schedule (twilight activity) is also common. Some species are active both during the day and night. Living at night can be seen as a form of niche differentiation, where a species' niche is partitioned not by resources but by time itself, i.e. temporal division of the ecological niche. It can also be viewed as a form of crypsis, in other words an adaptation to avoid or enhance predation. There are other reasons for nocturnality as well, such as keeping out of the heat of the day. This is especially true in deserts, where many animals' nocturnal behavior prevents them from losing precious water during the hot, dry daytime. This is an adaptation that enhances osmoregulation.
Many species which are otherwise diurnal exhibit some nocturnal behaviour; for example, many seabirds and sea turtles attend breeding sites or colonies nocturnally to reduce the risk of predation (to themselves or their offspring) but are otherwise diurnal. Some animals are not really nocturnal and are instead crepuscular, being mostly active in twilight.
Nocturnal animals generally have highly developed senses of hearing and smell, and specially adapted eyesight. In zoos, nocturnal animals are usually kept in special night-illumination enclosures to reverse their normal sleep-wake cycle and to keep them active during the hours when visitors will be attempting to see them.
Some animals, such as cats, have eyes that can adapt to both night and day levels of illumination (see metaturnal). Others, e.g. bushbabies and bats, can only function at night.
A person who exhibits nocturnal habits is referred to as a night owl; he or she is of the "eveningness" chronotype.
Hehehe...so now you can call me 'the night owl' cause I'm a late sleeper...What about you?
Do you sleep early at night or early in the morning? Meaning that you sleep when the sun rises, exactly like a bat. Try not to sleep to late cause it will costs you your heatlh. I know nowadays it is hard to sleep early right? When we have lots of works to finish. However, teens and adults only need six hours of sleep. Adjust your timetable so that it will not only your work but also your health. Wondering what are other nocturnals' apart from bats and owls?

Hey, I wanna tell you one thing. I've seen a real life Binturong! I saw it when my father took the family to Zoo Taiping. It isreally cuddly and cute! Oooohhh...I really want to hug it if I could but alas, I couldn't. Huhuhu...Poor me...Hahaha! But maybe someday I could, when I grow up and achieve my ambition! Do you think I can?
