The liger is a hybrid cross between a male Panthera leo (lion), and a female Panthera tigris (Tiger) and is denoted scientifically as Panthera tigris × Panthera leo. A liger resembles a giant lion with diffused stripes. They are the largest cats in the world, although the Siberian Tiger is the largest pure sub-species. Like tigers, but unlike lions, ligers enjoy swimming. A similar hybrid, the offspring of a male tiger and a female lion is called a tigon.
