Quagga

In 1984, the quagga was the first extinct animal to have its DNA analysed, and the Quagga Project is trying to recreate the phenotype of hair coat pattern and related characteristics by selectively breeding Burchell's zebras.

It confirmed that the quagga was more closely related to zebras than to horses, with the quagga and mountain zebra (Equus zebra) sharing an ancestor 3–4 million years ago.

Altogether last year, Parks and Wildlife intercepted 148 boats infested with invasive quagga or zebra mussels before they reached state waters.

Anyone in southwest Washington that enjoys recreating on the Columbia, be they fishermen or recreational boaters, has a responsibility to take all necessary steps to help keep the Columbia River free of dangerous invasive species, such as quagga mussels.

Other invasive species that can be spread include quagga mussels, crested floating heart, and water hyacinth.

The quagga mussel, first discovered in the United States in 1989, is an invasive species that alters the food web by filtering water and removing plankton, according to the U.S. Geological Survey.

The highly invasive zebra and quagga mussels can wreak havoc in freshwater ecosystems and can clog dam systems, municipal water pipes, irrigation systems and treatment facilities.

Boats are being inspected for ANS, which is Aquatic Nuisance Species such as zebra or quagga mussels.

Aquatic invasive species like quagga mussels and zebra mussels are small organisms that could have huge impacts for Wyoming’s waters, boaters, and anglers.

For Manitoba residents, zebra and quagga mussels are becoming a concern for their negative effects on native fish species, as well as people who use the beaches.

Quagga and Zebra mussels are not native to the U.S. and are originally thought to come from Russia and the Ukraine.

Embryological evidence supports zebras being dark coloured with white as an addition. citation Living in the very southern end of the plains zebra's range, the quagga had a thick winter coat that moulted each year.

He considered the quagga (now extinct) well-suited to domestication due to being easy to train to saddle and harness.

His 1840 account reads as follows: The geographical range of the quagga does not appear to extend to the northward of the river Vaal.

In early 2006, the third and fourth generation animals produced by the project were considered looking much like the depictions and preserved specimens of the quagga.

It is poorly represented in the fossil record, and the identification of these fossils is uncertain, as they were collected at a time when the name quagga referred to all zebras.

Little is known about the quagga's behaviour, but it may have gathered into herds of 30–50 individuals.

Only one quagga was ever photographed alive and only 23 skins are preserved today.
