Amur Leopard

(Panthera pardus orientalis)







“The Amur Leopard may be the rarest big cat on Earth” 

The Amur leopard is an isolated subspecies of leopards surviving along the border of Russia and China. While the Amur leopard may be the most rare big cat on Earth, its numbers have been rebounding thanks to incredible conservation efforts.

Incredible Amur Leopard Facts! 

The Amur leopard lives in extreme environments in Russia’s far east and has unique adaptations like a coat that grows significantly during the winter season to protect it against harsh condition that can reach below -30 degrees Celsius!In 2000, a survey found just 30 Amur leopards in a small area along the border of Russia and China, making the Amur leopard the rarest big cat on Earth. Thanks to conservation efforts, today the Amur leopard’s population is estimated to have increased to more than 100 individuals in the wild, and more than 300 in zoos across the world.

Amur Leopard Scientific Name

The scientific name for the Amur leopard is Panthera pardus orientalis. The genus Panthera covers big cats ranging from tigers, to lions, to jaguars and leopards. Pardus originates from Greek and means ‘spotted,’ while orientalis relates to the geography Amur leopards inhabit, having been first described in Korea.



Amur Leopard Appearance

Like all leopard subspecies, the Amur leopard is covered by ‘rosette’ markings across its coat. The coloration on leopards varies with their surrounding environment, and as the Amur leopard lives in the most northerly environment of all leopard subspecies, in winter its coat becomes more pale than other subspecies. During the winter, its coat also grows about 7 cm (2.75 in) to insulate the Amur leopard from temperatures in its habitat that can reach -30 degrees Celsius (-24 F).

Male Amur leopards typically weigh 32 to 48 kg, while females weigh 25 to 43 kg. This makes the Amur leopard smaller than the African leopard subspecies on average, although The Wild Cats Conservation Alliance has recorded male Amur leopards reaching 75 kg (165 lbs).

Amur Leopard Behavior 

The Amur leopard is largely solitary with the exception of mothers with their offspring and adults during mating season. Like other leopard subspecies, the Amur leopard hunts nocturnally. However, camera traps have shown the species may be more active than other leopard subspecies during daylight hours.

Home range sizes vary depending on the habitat, food available, and the season. While home ranges have been observed exceeding 160 square km, the core areas where Amur leopards hunt is typically much smaller.



Amur Leopard Habitat

Today, Amur leopards lives in a small range along the Chinese-Russian border. Traditionally the subspecies ranged across Korea, and upper Manchuria. However, today almost its entire population lives in Russian forests about 30 mi (48 km) to the west of the Russian port city of Vladivostok.

Temperatures in this region can top over 30 degrees Celsius (90 F) during the summer and can drop below negative 30 degrees Celsius (-24 F) during the winter, making it a more extreme environment than where other leopards live. Amur leopards are most commonly observed on camera traps in higher altitudes along the temperate forests in the hills and mountains of the region.



Amur Leopard Population — How Many Amur Leopards Are Left?

In 2000, a survey of Amur leopards found that as few as 30 individuals remained in the wild, leaving the species critically close to extinction. Since that survey, a concerted effort by conservation groups and the governments of Russia and China has helped the population rebound.

Russia created a ‘Land of the Leopard Park’ that covers 647,000 acres of leopard habitat. Today, the vast majority of leopards live within the borders of this protected habitat.

As of 2018, its estimated that at least 103 leopards live in Russia, with a smaller number of sightings occurring across the borders of China, and North Korea.



Amur Leopard Diet and Prey

The Amur leopard is a carnivore that lives on a diet consisting predominately of sika deer, roe deer, and other small mammals such as squirrels, rodents, and hares. A solitary hunter, the Amur leopard ambushes its prey with bursts of energy that include tremendous leaping ability and speeds of up to 35 miles per hour (56 km/h).

Like other leopard subspecies, the Amur leopard can climb trees for resting and also protecting its kills from other predators and scavengers. Due to the extreme environments Amur leopards live in, winter proves more difficult when less prey is available and snow makes it difficult for leopards to blend in with their background. During this time, Amur leopards will expand their home range in search of more available prey.



Amur Leopard Predators and Threats 

The Amur leopard faces few threats from predators, aside from humans who have hunted Amur leopards for their coats. While the Amur leopard is a top predator in their habitat, their range does overlap with the Siberian tiger.

In many regions where tiger and leopard territories overlap, leopards have struggled with the competition of another apex predator. However, researchers watching the growth of Siberian tiger populations haven’t detected an adverse effect on Amur leopards.

Amur Leopard Reproduction and Life Cycles

Amur leopard females reach sexual maturity and can first breed at around three years of age. Gestation periods range from about 90-105 days. Litters can range between 1 to 6 cubs, although 2 to 3 cubs is the most common litter size.

Due to the extreme conditions Amur leopards live in, it takes longer to raise an adolescent to independence than leopard subspecies in Africa. Cubs may live with their mother for up to 24 months before establishing their own territory.

Amur Leopard in Zoos

While the remaining population of Amur leopards in the wild remains critically low, approximately 300 survive in zoos across the world.

Select zoos where you can see the Amur leopard in person:

Beardsley Zoo(Bridgeport, Connecticut): Welcomed two new Amur leopard cubs in March, 2019.Minnesota Zoo: Located in the zoo’s “Russia’s Grizzly Coast” section.Santa Barbara Zoo: Home to two Amur leopards, Ajax and Wyatt.Hogle Zoo (Salt Lake City, Utah): Home to Zaya and her calf Jilin, who was born In May, 2018.Denver Zoo: First arrived at the zoo in 1989!



Amur Leopard Facts 

A tunnel to help save the Amur leopard?

In 2016 Russia completed a 575 meter (1,886 ft) tunnel to divert traffic from an area where remaining Amur leopard populations remained. Russia and China have cooperated on protecting remaining Amur leopard populations. While the Chinese side of the border is more densely populated, the Russian habitat is largely uninhabited. Which has helped the species rebound.

The Amur leopard has tiny hooks on its tongue!

The amur leopard has “denticles” or tiny hooks on its tongue. These hooks allow the leopard to lick the bones of its prey and collect even more meat.

New habitat reintroduction could be in the Amur leopards future

While the wild population of Amur leopards has rebounded to more than 100 individuals as of 2018, the population in captivity remains far larger. Special environments such as Scotland’s Highland Wildlife Park have built specialized Amur leopard habitats with the goal of creating populations that can be reintroduced into the wild. The reintroduction of captive Amur leopards could increase the size of their habitat and continue increasing genetic diversity from today’s levels.

Amur Leopard FAQs (Frequently Asked Questions) 

Why is the Amur leopard endangered?

The Amur leopard is endangered predominately because of poaching for its coat and habitat loss. The species once ranged across the Korean peninsula, but is believed to have gone extinct there in the 1960s. Today Amur leopards are protected by anti-poaching laws and have protected habitat, but need to see its populations continue rebounding to escape threats posed by inbreeding and potentially devastating diseases.

Where do Amur leopards live today?

The Amur leopard lives in a small area in Russia’s Far East that’s roughly 7,000 square kilometers on the Russia and China border. Today, the vast majority of the population lives in a protected area in Russia named ‘Land of the Leopard Park,” although a small number of Amur leopards have been seen inside China’s side of the boarder.

What is being done to save the Amur leopard?

Russia has established a ‘Land of the Leopard Park’ with the aid of conservation groups. This park has been critical in seeing the population of Amur leopards more than triple between 2000 and 2018. In the future, Amur leopards from captivity could be released into the wild to continue expanding the species territory and helping the species survive threats like inbreeding from its limited population.

Black Rhinoceros

(Diceros Bicornis)







With a population that numbered one million at the beginning of the 20th century, today the black rhino is Critically Endangered 

The black rhino once roamed across a vast range in Africa, but heavy poaching has brought the species to the brink of extinction. Today, the black rhino is seeing its population rebound and is slowly being reintroduced to countries and environments the species vanished from in recent decades. 

Incredible Black Rhinoceros Facts!

Although critically endangered, black rhino populations have rebounded since hitting a low of just an estimated 2,475 individuals in 1993.The San Diego Zoo reports the black rhino can hit 40 miles per hour (64 km/hr), making it one of the fastest large animals on Earth!While black rhino populations are rebounding, the Western black rhino subspecies was declared extinct in 2011



Black Rhinoceros Scientific Name

The scientific name for the black rhino is Diceros bicornis. Diceros is derived from Greek and means “two horned.” Bicornis once again means “two horned,” but is Latin. The black rhino is one of three rhinoceros species that has two horns (in addition to the white and Sumatran rhinos).

Black Rhinoceros Appearance

The black rhinoceros (also known as the hook-lipped rhinoceros) is a large species of rhinoceros native to Africa. Despite its name, the black rhinoceros is actually fairly light in color with most black rhinoceros individuals having either white or grey skin.

The black rhino weighs between 800 kg to 1,400 kg (1,800-3,100 lbs). On average, black rhinos weigh less than half the size of the other African rhino species, the white rhino. Their weight is similar to the Javan rhinoceros in Asia.

The most distinguishable physical characteristic on black rhinos is their upper lip, which is triangular and evolved to help the species eat from shrubs and bushes. In addition, black rhinos have a much smaller “hump” on their upper back than white rhinos.



The ears of the black rhinoceros possess a relatively wide rotational range to detect sounds and an excellent sense of smell. However, with its relatively poor eyesight, the black rhino will often charge when startled as a defense mechanism. Black rhinos have been seen charging objects ranging from trees, to cars, to passing trains.

Black Rhino Horn

The black rhino has a front horn that can reach incredible lengths relative to its body size. While most black rhino horns don’t exceed 24 inches (61 cm), the longest ever recorded black rhino horn was 55 inches (140 cm)!

The black rhino’s back horn is generally smaller. Like all rhinos, the horns of the black rhino is made from Keratin, a protein also found in fingernails and hair, and is extremely strong. In addition to defense black rhino horns provide intimidation and can help the animal dig up roots and even break branches during feeding.

The primary reason black rhino populations have been declining is poaching for its horn.

Black Rhinoceros Behavior

Compared to the white rhino, the black rhino is a much more solitary animal. The sociability of black rhinos varies by their habitat. In wide-open savannahs the species can be much more spread out, with a single black rhino in a range of up to 100 square kilometers. In more dense vegetation, their range can decline to one rhino per square kilometer.
