Zebra

Zebras are mammals of the family Equidae. Zebras are African horses. They are in the same genus as the common horse, Equus caballus, and donkeys.

Appearance
All zebras have very short fur because they live in hot areas. Their fur has black and white stripes. The main part of the body has mostly vertical stripes, and the legs have horizontal stripes. They also have a dark line directly down their spine. Each of the different zebra species has different types of stripes. Each zebra has a unique pattern.McClintock, Dorcas 1976.

Despite many attempts, we do not really know what the advantage is of having those characteristic stripes. There are different species and sub-species of zebra, and they all have stripes, so scientists think it must be important.Larison, Brenda; Harrigan, Ryan J.; Thomassen, Henri A.; Rubenstein, Daniel I.; Chan-Golston, Alec M.; Li, Elizabeth; Smith, Thomas B.  2015. "How the zebra got its stripes: a problem with too many solutions". Royal Society Open Science. 2 (1): 140452. 

Life
Zebras are social animals that spend time in herds, they graze together and sometimes even groom each other. They can have babies (foals) when they are about five years old and can have one every year. Zebras mainly eat grass. They always live near water and are an endangered species. 

Zebras live in Africa, south of the Sahara desert.
