The liger, a hybrid of a lion and tiger, can grow to be much larger than its parent species. Exceptionally heavy male lions and tigers have been recorded to exceed 306 kg (675 pounds) in the wilderness, and weigh around 1,000 pounds (450 kg) in captivity. At the bottom, adult snow leopards usually weigh 22 to 55 kg (49 to 121 lb), with an exceptional specimen reaching 75 kg (165 lb). The range of weights exhibited by the species is large. Unlike the roaring cats in their family, the snow leopard is distinguished by the lack of a large pad of fibro-elastic tissue that allows for a large vocal fold. All five extant members of the genus Panthera contain this elongated hyoid but owing to differences in the larynx the snow leopard cannot roar. The roar in good conditions can be heard 8 or even 10 km away. The lion's larynx is longest, giving it the most robust roar. When it begins to vibrate the sound moves from a high to low air resistance which makes the roaring. When this large pad folds it creates a low natural frequency, causing the cartilage walls of the larynx to vibrate. This tissue is made of a thick collagen and elastic fiber that becomes denser as it approaches the epithelial mucosal lining. In the larynx there are vocal folds that produce the structure needed to stretch the ligament to a length that creates the roar effect. This sequence of bones the hyoid hangs from are tympanohyal, stylohyal, epihyal, and ceratohyal these are located in the mandible and skull. The larynx is attached to the hyoid bone that is hanging from a sequence of bones. ![]() The ability to roar comes from an elongated and specially adapted larynx and hyoid apparatus. The earliest big cat fossil, Panthera blytheae, dating to 4.1−5.95 MA, was discovered in southwest Tibet. Lions and leopards split from one another approximately 2 Ma. Between 3.6–2.5 Ma the jaguar diverged from the ancestor of lions and leopards. The ancestor of the lion, leopard, and jaguar split from other big cats from 4.3–3.8 Ma. The tiger then evolved into a unique species towards the end of the Pliocene epoch, approximately 3.2 Ma. The tiger and snow leopard diverged from the ancestral big cats approximately 3.9 Ma. The study reveals that the snow leopard and the tiger are sister species, while the lion, leopard, and jaguar are more closely related to each other. Ī 2010 study published in Molecular Phylogenetics and Evolution has given insight into the exact evolutionary relationships of the big cats. The Felinae, on the other hand, comprises mostly small to medium-sized cats, including the domestic cats, but also some larger cats such as the cougar and cheetah. It is estimated that the ancestors of most big cats split away from the Felinae about 6.37 million years ago. ![]() Their native ranges include the Americas, Africa, and Asia the leopard's range also extends into Europe, specifically in Russia. All cats are carnivores and some are efficient apex predators. ĭespite enormous differences in size, various cat species are quite similar in both structure and behaviour, with the exception of the cheetah, which significantly stands out from the other big and small cats. The term " big cat" is typically used to refer to any of the five living members of the genus Panthera, namely the tiger, lion, jaguar, leopard, and snow leopard, as well as the non- pantherine cheetah and cougar.
