Animals with names beginning with the letter Z are rare. In fact, there are only a handful of animals in the world which fit that criteria, including the zebra, zebu, zorilla and zebra sharks.
The most common animal in this category is the zebra. Zebras are only found in Africa. The stripes on a zebra are completely unique to each individual, meaning no two zebras are completely alike. The zebu is a strange animal that is like a cow but has a hump on its back. This animal is found in many places but is native to south Asia. The zorilla, or striped polecat, is a creature that resembles a skunk and is nocturnal. Underwater, there are zebra sharks and zebrafish. These creatures are so named because of the stripes and patterns which run along their body, giving them the same type of appearance as a zebra.
On the stranger end of the spectrum, there are also zonkeys and zorses. These animals are crossbreeds between two species. The zonkey is a cross between a zebra and donkey, and the zorse is a crossbreed between a zebra and horse. According to A-Z Animals, the zonkey and zorse are unable to produce offspring, thus making them single generation animals.
