Panthera is a genus of the family Felidae (the cats), which contains four well-known species: the Tiger, Lion, Leopard, and Jaguar. The genus comprises about half of the big cats. Only these four cat species have the anatomical changes enabling them to roar, due to a modification to the shape of their hyoid bone.
