Grévy's zebra
The Grévy's zebra is the largest of all wild equines. It is from head to tail with a tail, and stands high at the withers. These zebras weigh . Grévy's zebra differs from the other two zebras in its more primitive characteristics. It is particularly mule-like in appearance; the head is large, long, and narrow with elongated nostril openings; the ears are very large, rounded, and conical and the neck is short but thick. The zebra's muzzle is ash-grey to black in colour with the lips having whiskers. The mane is tall and erect; juveniles have a mane that extends to the length of the back and shortens as they reach adulthood.
Greater Vancouver Zoo
On April 20, 2009, it was reported that four zebras had died in early March, shortly after two African buffalo were introduced to their enclosure. The zoo did not make the incident public at the time. A spokesperson for the Vancouver Humane Society stated that the zebras were between five and 15 years old, and probably died from exertional myopathy, a muscle disease causing damage to muscle tissues which is caused by physiological changes (often extreme exertion, struggle, or stress). The spokesperson also stated that African buffalo are extremely dangerous and although the two species co-exist in the wild, they should not have been placed together in an enclosed space. The British Columbia Society for the Prevention of Cruelty to Animals has launched an investigation of the incident, while the Vancouver Humane Society will ask the Canadian Association of Zoos and Aquariums to investigate the incident and review the zoo's accreditation. The zoo replaced the dead animals with two new zebras.
