Strangest Animal Hybrids You Won’t Believe Exist

6. The Mule

The mule is the most bred hybrid animal because it’s usually a stronger docile, and longer-living animal. A mule is a crossbreed between a male donkey and a female horse. Compared to a horse of the same size, a mule is more likely to carry more weight, be submissive, and eat less. This makes the mule a prized possession among people in Africa and south-east Asia. Although some female mules have given birth, all male mules and 99% of female mules are sterile.
