Pantherinae
Pantherinae is a subfamily within the family Felidae; it was named and first described by Reginald Innes Pocock in 1917 as only including the ''Panthera'' species. 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 was one reason it was proposed to be retained in the genus ''Uncia''.

Felidae
Felidae () is the family of mammals in the order Carnivora colloquially referred to as cats, and constitutes a clade. A member of this family is also called a felid (). The term "cat" refers both to felids in general and specifically to the domestic cat (''Felis catus''). Felidae species exhibit the most diverse fur pattern of all terrestrial carnivores. Cats have retractile claws, slender muscular bodies and strong flexible forelimbs. Their teeth and facial muscles allow for a powerful bite. They are all obligate carnivores, and most are solitary predators ambushing or stalking their prey. Wild cats occur in Africa, Europe, Asia and the Americas. Some wild cat species are adapted to forest habitats, some to arid environments, and a few also to wetlands and mountainous terrain. Their activity patterns range from nocturnal and crepuscular to diurnal, depending on their preferred prey species. Reginald Innes Pocock divided the extant Felidae into three subfamilies: the P ...

Clouded Leopard
The clouded leopard (''Neofelis nebulosa''), also called the mainland clouded leopard, is a wild cat inhabiting dense forests from the foothills of the Himalayas through mainland Southeast Asia into South China. In the early 19th century, a clouded leopard was brought to London from China and described in 1821. It has large dusky-grey blotches and irregular spots and stripes reminiscent of clouds. Its head-and-body length ranges from with a long tail. It uses its tail for balancing when moving in trees and is able to climb down vertical tree trunks head first. It rests in trees during the day and hunts by night on the forest floor. The clouded leopard is the first cat that genetically diverged 9.32 to 4.47 million years ago from the common ancestor of the pantherine cats. Today, the clouded leopard is locally extinct in Singapore, Taiwan, and possibly Hainan Island and Vietnam. Its total population is suspected to be fewer than 10,000 mature individuals, with a decreasing pop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jaguar
The jaguar (''Panthera onca'') is a large cat species and the only living member of the genus '' Panthera'' native to the Americas. With a body length of up to and a weight of up to , it is the largest cat species in the Americas and the third largest in the world. Its distinctively marked coat features pale yellow to tan colored fur covered by spots that transition to rosettes on the sides, although a melanistic black coat appears in some individuals. The jaguar's powerful bite allows it to pierce the carapaces of turtles and tortoises, and to employ an unusual killing method: it bites directly through the skull of mammalian prey between the ears to deliver a fatal blow to the brain. The modern jaguar's ancestors probably entered the Americas from Eurasia during the Early Pleistocene via the land bridge that once spanned the Bering Strait. Today, the jaguar's range extends from core Southwestern United States across Mexico and much of Central America, the Amazon rainfo ...

Lion
The lion (''Panthera leo'') is a large Felidae, cat of the genus ''Panthera'' native to Africa and India. It has a muscular, broad-chested body; short, rounded head; round ears; and a hairy tuft at the end of its tail. It is sexually dimorphic; adult male lions are larger than females and have a prominent mane. It is a social species, forming groups called ''prides''. A lion's pride consists of a few adult males, related females, and cubs. Groups of female lions usually hunt together, preying mostly on large ungulates. The lion is an apex predator, apex and keystone predator; although some lions scavenge when opportunities occur and have been known to hunt Human, humans, lions typically don't actively seek out and prey on humans. The lion inhabits grasslands, savannas and shrublands. It is usually more diurnality, diurnal than other wild cats, but when persecuted, it adapts to being active nocturnality, at night and crepuscular, at twilight. During the Neolithic period, the li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panthera
''Panthera'' is a genus within the family (biology), family Felidae that was named and described by Lorenz Oken in 1816 who placed all the spotted cats in this group. Reginald Innes Pocock revised the classification of this genus in 1916 as comprising the tiger (''P. tigris''), lion (''P. leo''), jaguar (''P. onca''), and leopard (''P. pardus'') on the basis of common Cranial bones, cranial features. Results of genetic analysis indicate that the snow leopard (formerly ''Uncia uncia'') also belongs to the genus ''Panthera'' (''P. uncia''), a classification that was accepted by IUCN Red List assessors in 2008. The tiger, lion, jaguar and leopard are the only cat species with anatomical structures that enable them to Roar (utterance), roar; the snow leopard cannot. The primary reason for this was formerly assumed to be the incomplete ossification of the hyoid bone. However, new studies show the ability to roar is due to other Morphology (biology), morphological features, especiall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neofelis
''Neofelis'' is a genus comprising two extant cat species in Southeast Asia: the clouded leopard (''Neofelis nebulosa'') of mainland Asia, and the Sunda clouded leopard (''Neofelis diardi'') of Sumatra and Borneo The scientific name ''Neofelis'' is a composite of the Greek word ''neo-'' (νέος-) meaning 'young' and 'new', and the Latin word ''fēles'' meaning 'cat'. Taxonomic history The generic name ''Neofelis'' was first proposed by John Edward Gray in 1867 as comprising two species; ''Neofelis macrocelis'' occurring in the Himalaya, Malacca, and Thailand, and ''Neofelis brachyurus'' occurring in the former Formosa.Gray, J.E. (1867)''Notes on the skulls of the Cats. 5. Neofelis'' Page 265–266 in: Proceedings of the Scientific Meetings of the Zoological Society of London for the year 1867. Reginald Innes Pocock recognized the taxonomic classification of ''Neofelis'' in 1917, but admitted only the single species ''Neofelis nebulosa'' with several subspecies and ''macrocel ...

Leopard
The leopard (''Panthera pardus'') is one of the five extant species in the genus '' Panthera'', a member of the cat family, Felidae. It occurs in a wide range in sub-Saharan Africa, in some parts of Western and Central Asia, Southern Russia, and on the Indian subcontinent to Southeast and East Asia. It is listed as Vulnerable on the IUCN Red List because leopard populations are threatened by habitat loss and fragmentation, and are declining in large parts of the global range. The leopard is considered locally extinct in Hong Kong, Singapore, South Korea, Jordan, Morocco, Togo, the United Arab Emirates, Uzbekistan, Lebanon, Mauritania, Kuwait, Syria, Libya, Tunisia and most likely in North Korea, Gambia, Laos, Lesotho, Tajikistan, Vietnam and Israel. Contemporary records suggest that the leopard occurs in only 25% of its historical global range. Compared to other wild cats, the leopard has relatively short legs and a long body with a large skull. Its fur is marked with rosett ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Felinae
The Felinae are a subfamily of the family Felidae. This subfamily comprises the small cats having a bony hyoid, because of which they are able to 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; thus excluding all fossil cat species. Characteristics The members of the Felinae have retractile claws that are protected by at least one cutaneous lobe. Their larynx is kept close to the base of the skull by an 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 ''Felis''. In 1917, Reginald Innes Pocock also subordinated the following genera to the Felinae that had been propo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roar (animal)
A roar is a type of animal vocalization that is deep and resonating. Many mammals have evolved to produce roars and other roar-like vocals for purposes such as long-distance communication and intimidation. These include various species of big cats, bears, pinnipeds, bovids, deer, elephants and simians. The anatomical basis for the ability to roar often involves modifications to the larynx and hyoid bone and enlarged internal air spaces for low-frequency vocal resonation. While roaring, animals may stretch out their necks and elevate their heads to increase the space for resonance. Definition The definition of "roar" has varied between species. However Weissengruber et al. (2002) have given a more general description of roars as consisting of both a low pitch and low formant. They have used the roars of lions and red deer as quintessential examples of the sound. Other researchers have mentioned similar "roar-like" vocalizations in which either the pitch or format is still higher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mucosal
A mucous membrane or mucosa is a membrane that lines various cavities in the body of an organism and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue. It is mostly of endodermal origin and is continuous with the skin at body openings such as the eyes, eyelids, ears, inside the nose, inside the mouth, lips, the genital areas, the urethral opening and the anus. Some mucous membranes secrete mucus, a thick protective fluid. The function of the membrane is to stop pathogens and dirt from entering the body and to prevent bodily tissues from becoming dehydrated. Structure The mucosa is composed of one or more layers of epithelial cells that secrete mucus, and an underlying lamina propria of loose connective tissue. The type of cells and type of mucus secreted vary from organ to organ and each can differ along a given tract. Mucous membranes line the digestive, respiratory and reproductive tr ...

Vocalis Muscle
The thyroarytenoid muscle is a broad, thin muscle that forms the body of the vocal fold and that supports the wall of the ventricle and its appendix. It functions to shorten the vocal folds. Structure It arises in front from the lower half of the angle of the thyroid cartilage, and from the middle cricothyroid ligament. Its fibers pass backward and laterally, to be inserted into the base and anterior surface of the arytenoid cartilage. Parts The lower and deeper fibers of the muscle can be differentiated as a triangular band which is inserted into the vocal process of the arytenoid cartilage, and into the adjacent portion of its anterior surface; it is termed the ''Vocalis'', and lies parallel with the vocal ligament, to which it is adherent.Frank H. Netter, MD "Atlas of Human anatomy", 7th Edition, 2019, Plate 91, superior view The vocal muscle is the upper portion of the thyroarytenoid muscle which is primarily involved in producing speech. A considerable number of the fibers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cricothyroid Muscle
The cricothyroid muscle is the only tensor muscle of the larynx aiding with phonation. It is innervated by the superior laryngeal nerve. Its action tilts the thyroid forward to help tense the vocal cords. Structure The cricothyroid muscle originates from the anterolateral aspect of the cricoid cartilage, and inserts to the inferior cornu and lower lamina of the thyroid cartilage. Innervation This muscle is the only laryngeal muscle innervated by the superior laryngeal branch of the vagus nerve known as the superior laryngeal nerve. Function The cricothyroid muscle produces tension and elongation of the vocal cords. They draw up the arch of the cricoid cartilage and tilt back the upper border of the cricoid cartilage lamina. The distance between the vocal processes and the angle of the thyroid is increased, and the folds are consequently elongated, resulting in higher pitch phonation. They work as antagonists to the posterior cricoarytenoid muscles. Clinical significance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
