Ass or donkey

The donkey or ass (Equus asinus) is a member of Horse family. Wild donkeys are only found in Northern Africa and the Arabian peninsula and can become 25 to 30 years of age. Predators of the donkey are lions and wolves. Donkeys have great sense of self-preservation, hence they will not do anything which will put themselves in any danger. This behavior has resulted in donkeys being called stubborn, although this is the result of the misinterpretation of their behavior. A donkey can be cross-bred with a horse to produce a mule or a hinny. A hinny is the offspring of a male horse and a female donkey (jenny). A mule is the offspring of a male donkey (jack) and a female horse. Both are almost always sterile since horses have 64 chromosomes and donkeys have 62, which results in offspring with an uneven 63 chromosomes.
