It's said that ligers (a male lion + a female tiger) only exist in captivity where they are deliberately bred. They grow to be very large very quickly and are reportedly the biggest cats in the world. Pictured above is Hercules, the largest liger in the world. He weighs over 410 kg (904 lbs).
When a male tiger and a female lion reproduce, this is the final result.

A rare combination of a male Jaguar and a female lion. Pictured above are Jahzara and Tsunami, born in Ontario Canada's Bear Creek Wildlife Sanctuary.

This hybrid species (a narwhal and beluga) is extremely rare. Increased sightings, however, are being made in the North Atlantic.
