Each subspecies varies slightly in size, habitat, and adaptations but share many common traits. Compared to Amur tigers, Damai has a smaller body and has deep orange coat coloring with lots of dark stripes. The second is urban sprawl and the encroachment of towns and cities into tiger territories, which displaces the cats and leads to killing by humans provoked by fear.

The normal litter size is two to four, though up to seven cubs have been recorded. They are born blind, and, even when their eyes open, opacity prevents clear vision for six to eight weeks. There is thus a long period of weaning, tutelage, and training during which cub mortality is high, especially if food is scarce. During this supplies in accounting time, the offspring must endure long periods of absence by the mother while she is away hunting. Weaker cubs get less food because of the aggressiveness of their stronger siblings as food is less frequently made available. The cubs remain with the mother until about the second year, when they are nearly adult and are able to kill prey for themselves.
- Deer are dichromats – meaning they are red-green colourblind.5 So, an orange tiger looks a shade of green to them.
- Its knowledge exchange platform, WildTigers Listserv, has more than 500 tiger conservation professionals as members.
- Conservation efforts are underway in different countries, with initiatives focusing on habitat preservation, anti-poaching measures and reducing human-tiger conflict.
- In regions where natural prey is scarce, tigers may turn to hunting livestock, leading to conflicts with humans.
The tiger is an apex predator and preys mainly on ungulates, which it takes by ambush. It lives a mostly solitary life and occupies home ranges, defending these from individuals of the same sex. The range of a male tiger overlaps with that of multiple females with whom he mates. Females give birth to usually two or three cubs that stay with their mother for about two years. When becoming independent, they leave their mother’s home range and establish their own.

Tigers require large habitats, which means they come under pressure from human activity, such as farming and logging. Their home ranges vary from 20 sq km (7.7 sq miles), to about 400 sq km (154 sq miles).12 Per 100 sq km, there could be as many as 15 to 19 tigers.13 Females ranges are smaller than males. Tigers hunt using their stealthy skills and stripey coats, which camouflage them in the forest.
What threats do tigers face?
Tiger populations occupy about 5 percent of their historical range, making conservation necessary. Tigers haunt the ruins of buildings such as courts and temples and are at home in habitats ranging from dry grassland to rainforest. Grasslands, mixed grassland-forests, and deciduous rather than densely canopied forests support maximum population densities, as these habitats maintain the highest number of prey species.
Tigers and humans
In human care, or on rare occasions in the wild, a tiger can live up to 20 years. However, approximately half of all wild tiger cubs do not survive past the first two years of life. Only 40 percent of those that reach independence actually live to establish a territory and produce young. The risk of mortality remains high for adult tigers due to their territorial nature, which often results in direct competition with conspecifics, or members of the same species.
Tiger: A Lone Hunter and Apex Predator
Since the early 20th century, tiger populations have lost at least 93% of their historic range and are locally extinct in West and Central Asia, in large areas of China and on the islands of Java and Bali. It is listed as Endangered on the IUCN Red List of Threatened Species, as its range is thought to have declined by 53% to 68% since the late 1990s. Major threats to tigers are habitat destruction and fragmentation due to deforestation, poaching for fur and the illegal trade of body parts for medicinal purposes.
Tiger Conservation
Although poaching has been responsible for keeping the number of tigers low during the past three decades, wild tigers would still be threatened even if all poaching ceased. In countries such as India, the needs of rapidly growing human populations over the last two centuries have reduced both the quantity and the quality of tiger habitat. Forests and grasslands so favored by the tiger are cleared for agriculture. Reduction in the tiger’s prey populations results in greater dependence on livestock and the consequent retribution from people.
Size
Each tiger maintains a large territory, which it marks with scent markings and scratch marks on trees. The size of a tiger’s range depends on the availability of prey and the density of the population. Tigers are the largest of the big cats, with some males reaching weights of 660 pounds (299.4 kilograms) and lengths of almost 11 feet (3.4 meters), including their tails. Tigers are threatened by human activity and climate change as they contend with losing their habitat to logging, farming and the expansion of human settlements. But across Asia these forests are being chopped up and fragmented by roads, farms and logging. Tigers mate throughout the year, rather than having mating seasons.7 Tigers form mating pairs – though one male might have access to more than one female – but only interact with each other during mating.
Because of this, researchers can use stripe patterns to identify different individuals when studying tigers in the wild. Tigers are powerful hunters with sharp teeth, strong jaws and agile bodies. They are the largest terrestrial mammal whose diet consists entirely of meat; the largest tiger ever recorded was an Amur tiger. In fact, without fur, it is difficult to distinguish a tiger from a lion. As part of the GTRP, the Smithsonian prepared a Global Support Program in Capacity Building and Knowledge Sharing through regional training programs in Asia and Core Learning Programs on conservation best practices.
- This makes it difficult for them to find mates and maintain genetic diversity, further threatening their survival.
- There are several subspecies of tigers, including the Bengal tiger (P. t. tigris), Siberian tiger (P. t. altaica), Sumatran tiger (P. t. Sumatra), and the extinct Caspian tiger (P. t. virgata).
- They need dense forests rather than open areas to hunt, as they rely on camouflage and stealth to sneak up on their prey.
- This is a little bit of a contentious topic which is currently under review by the International Union for Conservation of Nature (IUCN) Species Survival Commission Cat Specialist Group.
Tigers eat large prey animals like deer and wild pigs, though they make exceptions for some small animals, including porcupines. After consuming what they can of their prey, tigers hide animal carcasses from scavengers so they can return to them later. There are several subspecies of tigers, including the Bengal tiger (P. t. tigris), Siberian tiger (P. t. altaica), Sumatran tiger (P. t. Sumatra), and the extinct Caspian tiger (P. t. virgata).
The tiger’s closest relatives are the lion and jaguar; their shared ancestor likely lived around 4 to 6 million years ago. Tigers are found across a wide range of habitats, from the Siberian taiga to the tropical forests of Southeast Asia. Historically, their range spanned much of Asia, but due to habitat loss and poaching, tigers now occupy only about 7% of their original territory. Their future relies heavily on the protection of habitat within their range, which overlaps with areas of significant and continued human population growth.
While tigers might appear bright orange to us, and therefore stand out against the green backdrop of the forest, their prey see something different. Deer are dichromats – meaning they are red-green colourblind.5 So, an orange tiger looks a shade of green to them. The stripes add to their camouflage effect by breaking up their outlines against the foliage. Over time, tigers developed unique subspecies adapted to their particular habitats.
Comparatively, Sumatran tigers are downright minuscule, topping out at 310 pounds (140.6 kilograms) and 8 feet (2.4 meters). The best estimate for the total number of tigers in the wild is 5,578.18 It is thought that 70% of these are mature adults, which means there are at most 3,905 tigers who are able to reproduce. Tigers use their sense of smell for communication rather than hunting prey.
The greatest of the Gupta emperors of ancient India, Samudra, minted special gold coins depicting him slaying tigers. Tippu Sultan even vented his frustration at his inability to defeat the British by ordering a special life-size toy, complete with sounds, of a tiger mauling a British soldier. Tigers have been prominent in human culture, from Hindu and Chinese mythology to ancient royal emblems. However, human-tiger interactions have been both reverential and dangerous. Tigers have occasionally attacked humans, especially in regions with scarce natural prey, leading to conflict.
They thrive in temperate, tropical or evergreen forests, mangrove swamps and grasslands. Amur tigers are primarily found in Far-East Russia, although there are small populations across the border into China and potentially North Korea. A tiger’s range within these regions is determined by the availability of prey. The population decline since 1999 has been attributed to poaching as well as human activity resulting in habitat loss.
Its knowledge exchange platform, WildTigers Listserv, has more than 500 tiger conservation professionals as members. Historically, tigers existed throughout much of Eastern and Southern Asia, as well as in parts of Central and Western Asia and the Middle East, surrounding the Caspian Sea. Their range has diminished significantly as human populations have expanded. It is believed they currently occupy just 7 percent of their historic range. Tigers hunt by stalking their prey, using their striped coats as camouflage to get as close as possible before launching a powerful, short-range attack. They rely on their strong jaws and sharp claws to deliver a killing bite, usually to the neck or throat of the prey.
The tiger is among the most popular of the world’s charismatic megafauna. It has been kept in captivity since ancient times and has been trained to perform in circuses and other entertainment shows. The tiger featured prominently in the ancient mythology and folklore of cultures throughout its historic range and has continued to appear in culture worldwide. She can often be found sleeping in the heated dens on cooler days or along the wall in the shade on hot days. Damai likes to play with a large, weighted enrichment ball that rolls back toward her when she hits it.
