Big Cat

Despite enormous differences in size, the various species of cat are quite similar in both structure and behavior, with the exception of the cheetah, which is significantly different from any of the big or small cats. All cats are carnivores and efficient predators, in fact they are apex predators. Their range includes the Americas, Africa, Asia, and Europe.
The ability to roar comes from an elongated and specially adapted larynx and hyoid apparatus. (However, the snow leopard cannot roar, despite having hyoid morphology similar to roaring cats.) When air passes through the larynx on the way from the lungs, the cartilage walls of the larynx vibrate, producing sound. The lion's larynx is longest, giving it the most robust roar.
