Rosettes of a jaguar

A rosette is a rose-like marking or formation found on the fur and skin of some animals, particularly cats. [1] [2] Rosettes are used to camouflage the animal, either as a defense mechanism or as a stalking tool. Predators use their rosettes to simulate the different shifting of shadows and shade, helping the animals to remain hidden from their prey. Rosettes can be grouped in clusters around other spots, or may appear as blotches on the fur.

Leopard

The leopard (Panthera pardus) has a wide variety of coat coloration. On each color variation, the leopard has rosette patterns on their backs, flanks, and limbs. They also have patterns that are considered to be spots and not rosettes on their heads, stomach, and limbs. [3]

Jaguar

Like the leopard, the jaguar (Panthera onca) has a wide variety of coat coloration. The jaguar can have a coat in colors ranging from white to black with the most common residing in brownish yellow area. These big cats have rosettes on their bodies in random combination and pattern. [4]

Lion (cub)

Young lion (Panthera leo) cubs have rosette patterns on their legs and abdomen regions. These rosettes usually do not transfer into adulthood and fade as the cub ages. However, some mature lions may keep traces of their rosette patterns throughout life. [5] For the lion cub, the rosette markings act as camouflage in long grasses and bushes. [6]

Bengal Cat

The bengal cat (Felis catus x Prionailurus bengalensis) is a descendent from a combination of domestic cats and leopard cat lineage. This domesticated cat has a distinct coat pattern with a combination of rosettes, spots, and stripes. [7]

Cheetah

While individual cheetahs (Acinonyx jubatus) do have distinct and identifiable coat patterns like leopards or jaguars, the cheetah's patterns are considered to be spots, not rosettes. [8]

Ocelot

Ocelots (leopardus pardalis) have a coat pattern that may look like rosettes, however is considered to be a combination of spots and stripes. [9]

<span class="mw-page-title-main">Jaguar</span> Large cat native to the Americas

The jaguar 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 1.85 m and a weight of up to 158 kg (348 lb), it is the biggest 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.

A black panther is the melanistic colour variant of the leopard and the jaguar. Black panthers of both species have excess black pigments, but their typical rosettes are also present. They have been documented mostly in tropical forests, with black leopards in Africa and Asia, and black jaguars in South America. Melanism is caused by a recessive allele in the leopard, and by a dominant allele in the jaguar.

<span class="mw-page-title-main">Leopard</span> Large spotted cat native to Africa and Asia

The leopard is one of the five extant species in the genus Panthera. It has a pale yellowish to dark golden fur with dark spots grouped in rosettes. Its body is slender and muscular reaching a length of 92–183 cm (36–72 in) with a 66–102 cm (26–40 in) long tail and a shoulder height of 60–70 cm (24–28 in). Males typically weigh 30.9–72 kg (68–159 lb), and females 20.5–43 kg (45–95 lb).

Panthera is a genus within the 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, as well as a number of extinct species, including the cave lion and American lion.

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.

<span class="mw-page-title-main">Ocelot</span> Small wild cat

The ocelot is a medium-sized spotted wild cat that reaches 40–50 cm (16–20 in) at the shoulders and weighs between 7 and 15.5 kg on average. It is native to the southwestern United States, Mexico, Central and South America, and the Caribbean islands of Trinidad and Margarita. Carl Linnaeus scientifically described it in 1758. Two subspecies are recognized.

A purr or whirr is a tonal fluttering sound made by some species of felids, including both larger, outdoor cats and the domestic cat, as well as two species of genets. It varies in loudness and tone among species and in the same animal. In smaller and domestic cats it is known as a purr, while in larger felids, such as the panther, it is called a whirr.

<span class="mw-page-title-main">Congolese spotted lion</span> Hybrid carnivore

A Congolese spotted lion, also known by the portmanteau lijagulep, is the hybrid of a male lion and female jaguar-leopard hybrid. Several lijaguleps have been bred, but only one appears to have been exhibited as a Congolese spotted lion. It was most likely given that name by a showman because the public were more interested in exotic captured animals than in captive-bred hybrids.

A pumapard is a hybrid of a cougar and a leopard. Both male cougar with female leopard and male leopard with female cougar pairings have produced offspring. In general, these hybrids have exhibited a tendency to dwarfism.

A Panthera hybrid is a crossbreed between individuals of any of the five species of the genus Panthera: the tiger, lion, jaguar, leopard, and snow leopard. Most hybrids would not be perpetuated in the wild as the territories of the parental species do not overlap and the males are usually infertile. Mitochondrial genome research revealed that wild hybrids were also present in ancient times. The mitochondrial genomes of the snow leopard and the lion were more similar to each other than to other Panthera species, indicating that at some point in their history, the female progeny of male ancestors of modern snow leopards and female ancestors of modern lions interbred with male ancestors of modern snow leopards.

A tabby cat, or simply tabby, is any domestic cat with a distinctive M-shaped marking on its forehead, stripes by its eyes and across its cheeks, along its back, around its legs and tail, and characteristic striped, dotted, lined, flecked, banded, or swirled patterns on the body: neck, shoulders, sides, flanks, chest, and abdomen. The four known distinct patterns, each having a sound genetic explanation, are the mackerel, classic or blotched, ticked, and spotted tabby patterns.

Panthera Corporation, or Panthera, is a charitable organization devoted to preserving wild cats and their ecosystems around the globe. Founded in 2006, Panthera is devoted to the conservation of the world’s 40 species of wild cats and the vast ecosystems they inhabit. Their team of biologists, data scientists, law enforcement experts and wild cat advocates studies and protects the seven species of big cats: cheetahs, jaguars, leopards, lions, pumas, snow leopards and tigers. Panthera also creates targeted conservation strategies for the world’s most threatened and overlooked small cats, such as fishing cats, ocelots and Andean cats. The organization has offices in New York City and Europe, as well as offices in Mesoamerica, South America, Africa and Asia.
