Zebras reproduce sexually: The male zebra, which is called a stallion, mounts a female zebra, which is called a mare, and deposits sperm in the mare's vagina via the stallion's penis. If the mating is successful, the mare births a single foal 12 to 13 months later.Know More
Zebra herds typically consist of a stallion and several mares, comprising a group known as a harem. Stallions compete with one another to lay claim to a harem. Once a stallion emerges victorious, his claim is challenged only when other stallions perceive weakness due to disease or injury.
Stallions reach sexual maturity at 4 years old, while mares reach sexual maturity between 2 and 4 years old. Like other equine species, a zebra mare in estrus — that is, in heat — often signals her willingness to breed with a stallion by "winking" the labia, or turning them outward.
The long gestation period observed in zebras allows a foal to develop sufficiently that, within minutes of being born, it is able to stand. In spite of this developmental advantage, infant mortality among zebra foals is approximately 50 percent. If the foal reaches maturity, the average expected lifespan in the wild is between 20 and 25 years.Learn more about Animal Reproduction
A male killer whale inserts its penis into a female whales vagina and releases semen to inseminate the female's eggs. The female vaginal opening is in the middle of three patches near the tail-end of the whale's body. The areas on either side of the vagina are mammary gland slits that contain the nursing nipples, which withdraw when not in use. A single black slit covers a male penis.Full Answer >
Horses reproduce by going through a process which includes fertilization, pregnancy and growth before the cycle starts all over again. Horses also have a hormone cycle that includes several phases to help ready the mare for fertilization.Full Answer >
Mammals reproduce sexually, via the union of sperm and egg cells. Except for five species of egg-laying mammals, called monotremes, all mammals give birth to live young.Full Answer >
Camels reproduce by copulating during breeding season after the males compete for dominance. After a gestation period of 12 to 14 months, the female gives birth to a calf that weighs up to 80 pounds and that can stand and walk a short time after being born.Full Answer >
