Ligers
Ligersare the cross of a male lion and a female tiger, and they are the largest of all living cats and felines. Their massive size may be a result of imprinted genes which are not fully expressed in their parents, but are left unchecked when the two different species mate. Some female ligers can grow to 10 feet in length and weigh more than 700 pounds. Ligers are distinct from tigons, which come from a female lion and male tiger. Various other big cat hybrids have been created too, including leopons (a leopard and a lion mix), jaguleps (a jaguar and leopard mix), and even lijaguleps (a lion and jagulep mix).

Zebroids
A zebroidis the offspring of a cross between a zebra and any other equine, usually a horse or a donkey. There are zorses, zonkeys, zonies and a host of other combinations. Zebroids are an interesting example of hybrids bred from species that have a radically different number of chromosomes. For instance, horses have 64 chromosomes and zebra have between 32 and 44 (depending on species). Even so, nature finds a way.

Grolar bears
The offspring of a grizzly bear and a polar bear, a grolar bearis one beast you don't want to meet in the woods. Interestingly, unlike many hybrid animals on this list, grolar bears are known to occur naturally in the wild. Some experts predict that polar bears may be driven to breed with grizzly bearsat an increased frequency due to global warming, and the fact that polar bears are being forced from their natural habitats on the polar ice

Wholphins
A cross between a false killer whale and an Atlantic bottlenose dolphin, wholphinsare hybrids that have been reported to exist in the wild. There are currently two in captivity, both at Sea Life Park in Hawaii. The wholphin's size, color and shape are intermediate between the parent species. Even their number of teeth is mixed; a bottlenose has 88 teeth, a false killer whale has 44 teeth, and a wholphin has 66.

Savannah cats
Savannah cats are the name given to the offspring of a domestic cat and a serval — a medium-sized, large-eared wild African cat. The unusual cross became popular among breedersat the end of the 20th century, and in 2001 the International Cat Association accepted it as a new registered breed. Interestingly, savannahs are much more social than typical domestic cats, and they are often compared to dogs in their loyalty. They can be trained to walk on a leash and even taught to play fetch.

Camas
A cama is a hybrid of two animals from different worlds — camels from Asia, and llamas from South America. The two species exhibit many differences, but camels and llamas are both camelids descended from a common ancestor that evolved in North America during the Palaeogene period. Camas were produced via artificial insemination to create an animal with the size and strength of the camel, but the more cooperative temperament of the llama. The unlikely fertilization was a success, but the result wasn't quite what breeders had hoped. Camas exhibit a camel-like temperament, but they are attracted to female llamas. (Proof that opposites really do attract!)

Beefalo
Beefaloare the fertile offspring of domestic cattle and American bison. Crosses also exist between domestic cattle and European bison (zubrons), and yaks (yakows). The name given to beefalo might be the most suggestive, since the breed was purposely created to combine the best characteristics of both animals with an eye towards beef production. A USDA study showed beefalo meat, like bison meat, tended to be lower in fat and cholesterol. They are also thought to produce less damage to rangeland than cattle.

Sheep-goats
This cross between a sheep and a goat is rare because goats and sheep each belong to a different genus. Though matings between the two are known to occur, the offspring most often is stillborn. Even so, live births have occurred, the most famous of which happened in Botswana in 2000. Called the Toast of Botswana, the animal was infertile but it had an active libido — so active, in fact, that it earned itself the nickname of "Bemya", meaning rapist.

Narwhal-beluga hybrid
Narwhals and beluga whales are the only two living species of the Monodontidae family, though narwhals are distinct in that they have a long, straight, spiraled tuskextending from their upper left jaw. Though extremely unusual, at least one hybrid between the two species has been documented from west Greenland.

Mules and hinnies
Perhaps the most widespread and useful of hybrids are mules (from a male donkey and a female horse) and hinnies (from a male horse and a female donkey). Reputed for their hard work and strength despite their medium size, mules are dependableand often exhibit higher intelligence then their purebred parents. All male mules and most female mules are infertile, so their continued existence depends entirely on human intervention.

Blood parrots
First created in Taiwan in 1986, blood parrots are the hybrid offspring of either the midas cichlid and the redhead cichlid, or a green or gold Severum with the red devil. It's a controversial fishbecause it has several anatomical deformities, including such a narrow opening for a mouth that it's difficult for them to feed. They are bred because some fish pet owners enjoy their bright orange colors.

Interesting. The plants and animals are forever evolving. As some species are getting extinct, others are coming into existence

Space booked!

I want to see a boa mate a reticulated python. There should be a fight between a lion, a tiger, a liger and a tiglion to know who is stronger.
