quagga

(kwăg`ə), extinct type of zebrazebra,
herbivorous hoofed African mammal of the genus Equus, which also includes the horse and the ass. It is distinguished by its striking pattern of black or dark brown stripes alternating with white.

. It formerly inhabited open plains in S Africa, where its range overlapped that of the plains zebra, or common zebra (Equus quagga, formerly E. burchellii). Its coat was sandy brown and its legs and tail whitish; only its head, neck, and shoulders were dark-striped. Living in herds and competing with domestic sheep for grass, quaggas were exterminated in the 19th cent.; the last died in 1883 in the Amsterdam Zoo. Analyses of DNA (genetic material) from a museum specimen indicate that the quagga is almost certainly a variant of the plains zebra rather than a separate species as was once believed. The South African Quagga Project is attempting to selectively breed plains zebras to recreate a zebra with quagga characteristics. Quaggas are classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.

Quagga

 

(Equus quagga), a species of zebra.

The quagga is found in southern Africa. There are five subspecies, differentiated by color. The quagga proper (E. quaggaquagga) was distinguished from other zebras in having less strongly developed transverse stripes on its trunk and legs. It became extinct in the wild around 1860, and the last one died in the Amsterdam Zoo in 1883. Other subspecies of quagga have transverse stripes across the entire body. Burchell’s quagga (E.quagga burchelli) became extinct in 1910. Chapman’s zebra (E.quagga antiquorum ), Selous’ zebra (E. quagga selousi) and Grant’s zebra (E. quagga boehmi) are found both in natural conditions and on wildlife preserves.

In the September 11, 2017 issue of The New Yorker, physician and Pulitzer Prize winning author, Siddhartha Mukherjee, MD, writes that the dilemma we face in treating the cancer patient may be very similar to why the quagga mussel is out of control in Lake Michigan but of no concern in the Dnieper.
Researchers have previously suggested that the quagga was a subgroup of plains zebras and not its own separate zebra species, and the new genetic analysis offers more evidence for that idea.
Prior to this detection, the Pacific Northwest remained one of the only regions in North America without invasive quagga and zebra mussels.
But a handful of others-sea lamprey, alewife, round goby, quagga mussel, zebra mussel, Eurasian watermilfoil, spiny water flea, and rusty crayfish-have conducted an all-out assault on the Great Lakes and are winning the battle.

They also recount the specific stories of several animals lost forever due to human activity, such as the dodo, moa, thylacine, and quagga. This beautifully designed book includes excellent nature photography that shows off the diverse wildlife threatened with extinction, from lovely two-A-page spreads of a tiger, polar bears, or macaws in their natural habitats, to smaller but striking images of forest elephants, the gray whale, or the giant anteater.
Historians from the US, Canada, South Africa, and Europe look at animals who responded to or were products of specific contexts, discussing killer whales in the Pacific Northwest, the rise and fall of feral burros in the American West, and the extinct quagga in South Africa, as well as animal sources in archives, including the Mexican National Archive, veterinary artifacts at the C.A.V.
