Big Cat
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. All cats descend from the ''Felidae'' family, sharing similar musculature, cardiovascular systems, skeletal frames, and behaviour. Both the cheetah and cougar differ physically from fellow big cats, and to a greater extent, other small cats. As obligate carnivores, big cats are considered apex predators, topping their food chain without natural predators of their own. Native ranges include the Americas, Africa, and Asia; the ranges of the leopard and tiger also extend into Europe, specifically in Russia.

Panthera
''Panthera'' is a genus within the family (biology), family Felidae, and one of two extant genera in the subfamily Pantherinae. It contains the largest living members of the cat family. There are five living species: the jaguar, leopard, lion, snow leopard and tiger. Numerous extinct species are also named, including the Panthera spelaea, cave lion and American lion. Etymology The word derives from Classical Latin , itself from the Ancient Greek (). Characteristics In ''Panthera'' species, the dorsal profile of the skull is flattish or evenly convex. The frontal interOrbit (anatomy), orbital area is not noticeably elevated, and the area behind the elevation is less steeply sloped. The basic Cranial cavity, cranial axis is nearly horizontal. The inner chamber of the Auditory bulla, bullae is large, the outer small. The partition between them is close to the external auditory meatus. The convexly rounded chin is sloping. All ''Panthera'' species have an incompletely ossified h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Americas
The Americas, sometimes collectively called America, are a landmass comprising the totality of North America and South America.''Webster's New World College Dictionary'', 2010 by Wiley Publishing, Inc., Cleveland, Ohio. When viewed as a single continent, the Americas or America is the 2nd largest continent by area after Asia, and is the 3rd largest continent by population. The Americas make up most of the land in Earth's Western Hemisphere and comprise the New World. Along with their Lists of islands of the Americas, associated islands, the Americas cover 8% of Earth's total surface area and 28.4% of its land area.

Domestic Cat
The cat (''Felis catus''), also referred to as the domestic cat or house cat, is a small Domestication, domesticated carnivorous mammal. It is the only domesticated species of the family Felidae. Advances in archaeology and genetics have shown that the domestication of the cat occurred in the Near East around 7500 BC. It is commonly kept as a pet and working cat, but also ranges freely as a feral cat avoiding human contact. It is valued by humans for companionship and its ability to kill vermin. Its retractable claws are adapted to killing small prey species such as mice and rats. It has a strong, flexible body, quick reflexes, and sharp teeth, and its night vision and sense of smell are well developed. It is a social species, but a solitary hunter and a crepuscular predator. Cat intelligence is evident in their ability to adapt, learn through observation, and solve problems. Research has shown they possess strong memories, exhibit neuroplasticity, and display cognitive skil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smithsonian Institution
The Smithsonian Institution ( ), or simply the Smithsonian, is a group of museums, Education center, education and Research institute, research centers, created by the Federal government of the United States, U.S. government "for the increase and diffusion of knowledge".

Puma (genus)
''Puma'' ( or ) is a genus in the family Felidae whose only extant species is the cougar (also known as the puma, mountain lion, and panther, among other names), and may also include several poorly known Old World fossil representatives (for example, '' Puma pardoides'', or Owen's panther, a large, cougar-like cat of Eurasia's Pliocene). In addition to these potential Old World fossils, a few New World fossil representatives are possible, such as '' Puma pumoides'' and the two species of the so-called " American cheetah", currently classified under the genus ''Miracinonyx''. Description Pumas are large, secretive cats. They are also commonly known as cougars and mountain lions, and are able to reach larger sizes than some other "big" cat individuals. Despite their large size, they are more closely related to smaller feline species than to lions or leopards. The two subspecies of pumas have similar characteristics but tend to vary in color and size. Pumas are the most adaptable fe ...

Acinonyx
''Acinonyx'' is a genus within the Felidae family. The only living species of the genus, the cheetah (''A. jubatus''), lives in open grasslands of Africa and Asia. Several fossil remains of cheetah-like cats were excavated that date to the late Pliocene and Middle Pleistocene. These cats occurred in Africa, parts of Europe and Asia about 10,000 years ago. Several similar species classified in the genus '' Miracinonyx'' lived in North America at the same time; these may have been more closely related to the genus '' Puma''. Taxonomy ''Acinonyx'' was proposed by Joshua Brookes in 1828. Between the late 18th century and the early 20th century, the following ''Acinonyx'' species and subspecies were described: * ''Felis jubatus'' by Johann Christian Daniel von Schreber in 1777 was based on earlier descriptions by Comte de Buffon and Thomas Pennant. ** ''Felis venatica'' by Griffith in 1821 was based on a sketch of a cheetah from India. ** ''Cynailurus soemmeringi'' by Fitzi ...

Felinae
The small cats or Felinae are a subfamily of Felidae distinguished by their bony hyoids, which let them purr but not roar. Other authors have proposed an alternative definition for this subfamily, as comprising only the living conical-toothed cat genera with two tribes, the Felini and Pantherini, and excluding the extinct sabre-toothed Machairodontinae. Characteristics The members of the Felinae have retractile claws that are protected by at least one cutaneous Lobe (anatomy), lobe. Their larynx is kept close to the base of the skull by an Ossification, ossified hyoid. They can purr owing to the vocal folds being shorter than . The cheetah ''Acinonyx'' does not have cutaneous sheaths for guarding claws. Taxonomy The term 'Felini' was first used in 1817 by Gotthelf Fischer von Waldheim, at the time for all the cat species that had been proposed as belonging to the Genus (biology), genus ''Felis''. In 1917, Reginald Innes Pocock also subordinated the following genera to the Felinae ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pantherinae
The Pantherinae is a subfamily of the Felidae; it was named and first described by Reginald Innes Pocock in 1917 as only including the ''Panthera'' species, but later also came to include the clouded leopards (genus ''Neofelis''). The Pantherinae genetically diverged from a common ancestor between and . Characteristics Pantherinae species are characterised by an imperfectly ossified hyoid bone with elastic tendons that enable their larynx to be mobile. They have a flat rhinarium that only barely reaches the dorsal side of the nose. The area between the nostrils is narrow, and not extended sidewards as in the Felinae. The ''Panthera'' species have a single, rounded, vocal fold with a thick mucosal lining, a large vocalis muscle, and a large cricothyroid muscle with long and narrow membranes. A vocal fold that is longer than enables all but the snow leopard among them to roar, as it has shorter vocal folds of that provide a lower resistance to airflow; this distinction w ...
