Tiger: The Largest Cat on Earth
Stripes Like Fingerprints
A Bengal tiger walks through tall grass in India. Her stripes run vertically across her orange coat, breaking up her outline against the dappled sunlight filtering through the grass. Her specific pattern — the exact position and width of each stripe — is unique to her, as individual as a human fingerprint.
Another tiger could have similar coloration, similar size, similar behavior. But no other tiger has exactly this stripe pattern. Researchers use these patterns to track individual tigers throughout their lives.
Tigers (Panthera tigris) are the largest cats on Earth, each one a unique individual, most of them now critically endangered in one of the most precarious conservation situations of any large mammal.

The Striped Future
Every wild tiger represents both the success of recent conservation and ongoing challenges.
India's population has doubled. Nepal has met ambitious targets. Russian populations have recovered. Protected areas have expanded. Community programs are reducing conflict.
Yet threats persist. Habitat fragmentation continues. Poaching remains a danger. Climate change approaches. Individual tigers face genetic bottlenecks in small populations. The next 20-30 years will determine whether multiple subspecies survive.
Each tiger in an Indian reserve, Russian forest, or Sumatran jungle is genetically unique, behaviorally distinct, and individually important to the species' survival. Their stripe patterns are records of individuals who walk our planet today.
For tigers to persist long-term requires:
- Continued habitat protection
- Aggressive anti-poaching
- Community cooperation
- International commitment
- Sustained funding
The tiger in the grass, stalking through jungle, swimming across rivers, raising cubs in a secluded den -- each represents 2 million years of tiger evolution and the continuous chain of individual tigers who came before.
Whether that chain continues depends on us.

Frequently Asked Questions
How big are tigers?
Tigers (Panthera tigris) are the largest cats in the world, significantly bigger than lions. Siberian tigers (the largest subspecies) reach: 3.3 meters length (body + tail), 320 kg weight (record was 384 kg), and 1.1 meters shoulder height. Bengal tigers are similar, with large males reaching 280 kg. Even smaller subspecies (Sumatran, Malayan) still typically exceed leopards and most other big cats. Females are 20-30% smaller than males. Individual tiger size varies by subspecies and habitat -- tigers in colder, larger-prey environments grow larger than tropical populations. They have massive paws (16-20 cm wide), powerful jaws capable of 1,050 PSI bite force, and muscular shoulders for bringing down large prey. Their teeth are among the longest of any land predator (up to 10 cm). Despite their impressive size, they are primarily ambush predators rather than long-distance runners. Their massive size allows them to tackle prey much larger than themselves -- they routinely kill buffalo, gaur, and large deer.
Are tiger stripes unique like fingerprints?
Yes, every tiger has a unique stripe pattern, similar to human fingerprints. The specific pattern of stripes -- their position, width, curvature, and number -- varies from tiger to tiger. Researchers use photo-identification of stripe patterns to track individual tigers throughout their lives, monitor populations, and study behavior. The stripes are actually on the skin, not just fur -- if a tiger's fur is shaved, the pattern is still visible on the skin underneath. Stripe patterns serve as camouflage in their natural habitats -- tall grass, dense forest, and dappled sunlight create conditions where vertical stripes break up the tiger's outline effectively. Different subspecies have different general stripe patterns: Bengal tigers tend to have wider stripes and warmer orange coloration; Siberian tigers have more pale coloring with fewer stripes adapted to snowy environments; Sumatran tigers have the closest-set stripes adapted to dense tropical forests. Despite these variations, each individual's pattern remains unique. This individual variation has been invaluable for tiger conservation research.
How many tigers are left in the wild?
Approximately 3,900-5,000 wild tigers remain globally, with populations varying significantly by region and subspecies. This represents a dramatic recovery from approximately 3,200 in 2010, when the lowest modern estimate was recorded. Current distribution: Bengal tigers (about 3,000 in India, Nepal, Bhutan, Bangladesh), Siberian tigers (500-600 in eastern Russia, limited China/North Korea), Indochinese tigers (200-500 across Southeast Asia), Malayan tigers (80-150 in Malaysia), Sumatran tigers (400-500 in Sumatra), South China tigers (functionally extinct in wild, some in captivity). Three subspecies are already extinct: Caspian tiger (1970s), Javan tiger (1980s), Bali tiger (1940s). Major causes of decline: habitat loss, prey depletion, poaching for body parts, human-tiger conflict. Current recovery has occurred primarily through protected area management in India, Nepal, Russia. India alone has doubled its tiger population since 2010 to over 3,000. However, habitat fragmentation and population isolation remain serious concerns. Without continued conservation effort, tigers could still face extinction in the wild.
What do tigers eat?
Tigers are apex predators that hunt medium to large mammals, primarily ungulates. Their typical diet varies by subspecies and habitat but includes: deer (most common prey -- sambar, chital, muntjac), wild boar (especially in certain regions), gaur (large wild cattle, up to 900 kg, tackled by male tigers), buffalo, young elephants (rare, requires specific circumstances), antelope species, and smaller prey like monkeys, porcupines, and fish when available. An adult tiger can eat 18-40 kg of meat in a single meal and consume up to 40 kg per kill. They hunt by ambush -- stalking close before a short rush or pouncing from concealment. Their hunting success rate is approximately 5-10% of attempts, which is actually lower than some smaller predators but offset by the large size of successful kills. They typically eat 50-60 kg of meat per week. Tigers can fast for extended periods (weeks) between successful hunts. They particularly hunt at dawn and dusk when their striped camouflage works best in low light. Their strength allows them to drag prey 50-100 meters to hide it before feeding.
Why are tigers so endangered?
Tigers face extinction due to: severe habitat loss (95% of historical range gone), poaching for body parts used in traditional medicine (bones, organs, skins), human-tiger conflict (tigers kill livestock; humans kill tigers), prey population declines reducing food sources, and fragmentation of remaining habitat into isolated pockets. Historical range covered most of Asia from eastern Turkey to eastern Russia, from Central Asia to Southeast Asia. Today, tigers occupy less than 5% of this range, in isolated fragments often too small to support viable breeding populations. Poaching for traditional Chinese medicine has been particularly devastating -- tiger bones, organs, and other parts are believed to have medicinal properties despite no scientific evidence. Illegal international trade continues despite CITES protection since 1975. Local human-tiger conflict in areas where tigers prey on livestock creates political resistance to conservation. Climate change is affecting tiger habitats in multiple regions. Without continuing aggressive protection, some tiger subspecies could go extinct within 20-30 years despite recent recovery efforts. India's conservation success shows tigers can recover with adequate protection, but requires sustained political and financial commitment.
