Big cat - wikipedia Big cat For other uses, see Big cat ( disambiguation ). The Liger ( Panthera leo × Panthera tigris ) is the largest and heaviest living member of the Felidae ( cat ) family. The informal term `` big cat '' is typically used to refer to any of the four largest ( living ) members of the entire Panthera genus. Among the five total species within the Panthera genus, these four are the only cats that are able to roar. In descending order of their maximum potential size, these four species are : tigers, lions, jaguars, and leopards, with the tiger ( Panthera tigris ) being the largest. A more liberal and expansive definition is sometimes used which may include the snow leopard, puma, clouded leopard, Sunda clouded leopard and / or cheetah, although these added species do not roar. Despite enormous differences in size, various species of cat 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. All cats are carnivores and efficient apex predators. Their range includes the Americas, Africa, Asia, and Europe. Contents 1 Roaring 2 Threats 3 Conservation 4 Species 5 Evolution 6 Gallery 7 References Roaring The ability to roar comes from an elongated and specially adapted larynx and hyoid apparatus. 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. All five extant members of the Panthera genus contain this elongated hyoid but due to differences in the larynx the snow leopard can not roar. Threats The principal threats to big cats vary by geographic location, but primarily are habitat destruction and poaching. In Africa many big cats are hunted by pastoralists or government ' problem animal control ' officers. Certain protected areas exist that shelter large and exceptionally visible populations of lions, hyenas, leopards, and cheetahs, such as Botswana 's Chobe, Kenya 's Masai Mara, and Tanzania 's Serengeti. Rather, it is outside these conservation areas where hunting poses the dominant threat to large carnivores. In the United States, 19 states have banned ownership of big cats and other dangerous exotic animals as pets, and the Captive Wildlife Safety Act bans the interstate sale and transportation of these animals. The initial Captive Wildlife Safety Act ( CWSA ) was signed into law on December 19, 2003. To address problems associated with the increasing trade in certain big cat species, the CSWA regulations were strengthened by a law passed on September 17, 2007. The big cat species addressed in these regulations are the lion, tiger, leopard, snow leopard, clouded leopard, cheetah, jaguar, cougar, and any hybrid combination any of these species ( liger, tigon, etc ) that results from breeding of these big cats. Private ownership of these big cats is not prohibited by this law but the law does make it illegal to transport, sell, or purchase them in interstate or foreign commerce. Although these regulations seem to provide a strong legal framework for controlling the commerce involving big cats, international organizations such as the World Wildlife Fund ( WWF ) have encouraged the U.S. to further strengthen these laws. The WWF is concerned that weaknesses in the existing U.S. regulations could be unintentionally helping to fuel the black market for tiger parts. Conservation For the population of the big cats, see List of carnivorans by population An animal sanctuary provides a refuge for animals to live out their natural lives in a protected environment. Usually these animal sanctuaries are the organizations which provide a home to big cats whose private owners are no longer able or willing to care for their big cats. However, use of the word sanctuary in an organization 's name is by itself no guarantee that it is a true animal sanctuary in the sense of a refuge. To be accepted by the United States Fish and Wildlife Service ( FWS ) as a bona fide animal sanctuary and to be eligible for an exemption from the prohibition of interstate movement of big cats under the Captive Wildlife Safety Act ( CWSA ), organizations must meet the following criteria : Must be a non-profit entity that is tax exempt under section 501 ( a ) of the Internal Revenue Code Cannot engage in commercial trade in big cat species, including their offspring, parts, and products made from them Cannot breed big cats Cannot allow direct contact between big cats and the public at their facilities Must keep records of transactions involving covered cats Must allow the Service to inspect their facilities, records, and animals at reasonable hours Species The lion, the tallest living species in the cat family, which includes the genus Panthera Family Felidae Genus Panthera Tiger, Panthera tigris Asia Lion, Panthera leo ( Sub-Saharan Africa, Gir Forest in India ; extinct in former range of southeast Europe, Middle East, much of Asia, and North America ) Jaguar, Panthera onca ( the Americas ; from the southern United States to northern Argentina ) Leopard, Panthera pardus ( Asia and Africa ) Snow leopard, Panthera uncia ( syn. Uncia uncia - mountains of central and south Asia ) Genus Acinonyx Cheetah, Acinonyx jubatus ( Sub-Saharan Africa and Iran ; extirpated in former range of India ) Genus Puma Puma / Cougar / Panther / Mountain lion Puma concolor ( North and South America ) Evolution. A 2010 study published in Molecular Phylogenetics and Evolution has given insight into the exact evolutionary relationships of the big cats. 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. The tiger and snow leopard diverged from the ancestral big cats approximately 3.9 Ma. The tiger then evolved into a unique species towards the end of the Pliocene epoch, approximately 3.2 Ma. The ancestor of the lion, leopard, and jaguar split from other big cats from 4.3 -- 3.8 Ma. Between 3.6 -- 2.5 Ma the jaguar diverged from the ancestor of lions and leopards. Lions and leopards split from one another approximately 2 Ma. The earliest big cat fossil, Panthera blytheae, dating to 4.1 − 5.95 MA, was discovered in southwest Tibet. 3.9 Ma 3.2 Ma Snow leopard Tiger 3.6 Ma Jaguar 2 Ma Lion Leopard Gallery Lion Cheetah Puma / Cougar / Panther / Mountain lion Jaguar Leopard Snow leopard Liger Tigon Tiger References ^ Jump up to : `` Big Cat Facts ''.
