A zorse or zebrula is the offspring of a zebra stallion and a horse mare. The zorse is shaped more like a horse than a zebra, but has boldly striped legs and, often, stripes on the body or neck. Like most other interspecies hybrids, it is infertile. Recently and especially in the United States the zorse became a circus and a domestic animal. Zorses are stronger smarter and faster than horses and are easily trained. They are also almost immune to hot weather, and zorses do not seem to tire.
