Jungle Island, an interactive animal theme park in Miami, is home to a liger named Hercules, the largest non-obese Liger, who is recognized by the Guinness Book of World Records as the largest living cat on Earth, weighing over 410 kg (904 lb). The liger is a hybrid cross between a male lion (Panthera leo) and a tigress (Panthera tigris). Thus, it has parents with the same genus but of different species. It is distinct from the similar hybrid tiglon. It is the largest of all known cats and extant felines.Ligers enjoy swimming, which is a characteristic of tigers, and are very sociable like lions. Ligers exist only in captivity because the habitats of the parental species do not overlap in the wild. Historically, when the Asiatic Lion was prolific the territories of lions and tigers did overlap and there are legends of ligers existing in the wild. Notably, ligers typically grow larger than either parent species, unlike tiglons which tend to be about as large a female tiger.
