Diurnality, plant or animal behavior characterized by activity during the day and sleeping at night. Cathemeral, a classification of organisms with sporadic and random intervals of activity during the day or night. Matutinal, a classification of organisms that are only or primarily active in the pre-dawn hours or early night.
Zebras and asses diverged from each other close to 2 mya. The mountain zebra diverged from the other species around 1.6 mya and the plains and Grévy's zebra split 1.4 mya. [21] A 2017 mitochondrial DNA study placed the Eurasian Equus ovodovi and the subgenus Sussemionus lineage as closer to zebras than to asses. [22]
Zebras have a less efficient digestive system than ruminants but food passage is twice as fast. [15] Thus, zebras are less selective in foraging, but they do spend much time eating. The zebra is a pioneer grazer and prepares the way for more specialised grazers such as blue wildebeests and Thomson's gazelles. [9] Lions feeding on a zebra
Ever wondered why zebras have stripes? Well, the researchers behind a new study think they have a pretty good answer to that question. WMAQ reports "California scientists say the animal's black ...
The mountain zebra (Equus zebra) is a zebra species in the family Equidae, native to southwestern Africa. There are two subspecies, the Cape mountain zebra ( E. z. zebra ) found in South Africa and Hartmann's mountain zebra ( E. z. hartmannae ) found in south-western Angola and Namibia.
The kiwi is a family of nocturnal birds endemic to New Zealand.. While it is difficult to say which came first, nocturnality or diurnality, a hypothesis in evolutionary biology, the nocturnal bottleneck theory, postulates that in the Mesozoic, many ancestors of modern-day mammals evolved nocturnal characteristics in order to avoid contact with the numerous diurnal predators.

The lion is a cathemeral felid. Cathemerality, sometimes called "metaturnality", is an organismal activity pattern of irregular intervals during the day or night in which food is acquired, socializing with other organisms occurs, and any other activities necessary for livelihood are undertaken. [1]
Three of the four black-and-white striped animals were quickly captured, but the fate of the fourth wasn’t immediately known Monday, Washington State Patrol Trooper Rick Johnson said. The zebras ...
