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
He posted pictures of the animals as three still roamed free, before troopers and the public came together to secure their capture. "This is a first for me and all [State Patrol] troopers involved ...
A 2013 phylogenetic study found that the plains zebra is more closely related to Grévy's zebras than mountain zebras. [14] The extinct quagga was originally classified as a distinct species. [ 15 ] Later genetic studies have placed it as the same species as the plains zebra, either a subspecies or just the southernmost population.
In Africa, the most dangerous species include black mambas, puff adders, and carpet vipers. In the Middle East, the species of greatest concern are carpet vipers and elapids ; in Central and South America, Bothrops (including the terciopelo or fer-de-lance) and Crotalus ( rattlesnakes ) are of greatest concern.
Burchell's zebras are described as being striped on the head, the neck, and the flanks, and sparsely down the upper segments of the limbs then fading to white. [5] One or two shadow stripes rest between the bold, broad stripes on the haunch. [5] This main distinguishing characteristic sets the Burchell's zebra apart from the other subspecies.
Why Zebras Don't Get Ulcers is a 1994 (2nd ed. 1998, 3rd ed. 2004) book by Stanford University biologist Robert M. Sapolsky. The book includes the subtitle "A Guide to Stress, Stress-related Diseases, and Coping" on the front cover of its third edition.
Superficially, Grévy's zebras' physical features can help to identify it from the other zebra species; their overall appearance is slightly closer to that of a mule, compared to the more "equine" (horse) appearance of the plains and mountain zebras. Compared to other zebra species, Grévy's are the tallest; they have mule-like, larger ears ...
