Six Living Subspecies — Three Already Gone
The tiger was once one species distributed across most of Asia. Three subspecies went extinct in the 20th century. Six survive today, all endangered or critically endangered.

The Life Stages of a Tiger
Tigers are solitary from a young age and mature relatively quickly for a large cat. A wild tiger's life is defined by the challenge of establishing and defending a territory large enough to sustain them — a task that begins in earnest before age 3 and becomes increasingly difficult as habitat shrinks.
Things About Tigers That Will Actually Surprise You
🐯 The Global Tiger Recovery Program, launched in 2010 at the St Petersburg Tiger Summit, set a goal of doubling wild tiger numbers by 2022 (TX2). By 2023, the global estimate had risen to approximately 3,726–5,578 — a genuine, hard-won recovery from the 2010 low. India, Nepal, and Bhutan drove most of the growth. But the Malayan, Sumatran, South China, and Indochinese subspecies continue to decline. The recovery is real but fragile.
Tigers and Humans — A Dangerous History
⚠️ Tigers are the most dangerous big cat to humans historically. The Champawat Tiger — a Bengal tigress in Nepal and northern India — killed an estimated 436 people between 1900 and 1907, the highest confirmed human death toll attributed to any single wild animal in recorded history. She was eventually shot by hunter Jim Corbett in 1907.
Tiger attacks on humans are relatively rare given how few wild tigers remain — but they are not trivial. The WWF and Indian wildlife authorities estimate that 50–100 people are killed by tigers in India annually, primarily in the Sundarbans delta region of West Bengal where the mangrove habitat forces unusually close contact between tigers and the local fishing and honey-gathering communities.
Why the Sundarbans Are Different
The Sundarbans — a vast mangrove delta shared between India and Bangladesh — holds one of the world's largest tiger populations (estimated 100–120 individuals on the Indian side alone). The geography forces a level of human-tiger overlap found nowhere else: fishermen and honey collectors enter the forest regularly, boats are small and low, and tigers have learned to ambush from the water's edge. Local communities wear masks on the back of their heads — tigers typically attack from behind — as a documented deterrent that reduced attacks in controlled studies.
When Tigers Attack
The vast majority of tiger attacks involve specific circumstances:
- Old or injured tigers that can no longer take down large prey — dental wear, injury, or porcupine quill infections can make a tiger shift to easier targets
- Surprise encounters at close range — tigers that have been startled or cornered
- Habitat overlap in the Sundarbans and other heavily populated areas where tiger territory and human activity overlap
- Tigresses with cubs — a mother perceiving a threat to her offspring is among the most dangerous scenarios
- Captive or zoo incidents — the majority of fatal tiger attacks in Western countries involve captive animals
Notable Man-Eaters of History
| Tiger | Region | Period | Attributed Deaths | Notes |
|---|---|---|---|---|
| Champawat Tiger | Nepal / Uttarakhand, India | 1900–1907 | 436 | Highest confirmed toll of any wild animal in history. Shot by Jim Corbett. |
| Tiger of Segur | Tamil Nadu, India | 1950s | ~40 | Operating near the Nilgiri Hills; responsible for numerous cattle and human kills. |
| Thak Tigress | Kumaon, India | 1938 | 4 confirmed | Also shot by Jim Corbett; his account in The Man-Eating Leopard of Rudraprayag documents the hunt. |
| Sundarbans Tigers (ongoing) | West Bengal / Bangladesh | Ongoing | 50–100/yr (India) | Multiple individuals; the only persistent man-eating tiger population in the modern world. |
📖 Jim Corbett (1875–1955) was a British-Indian hunter and conservationist who hunted some of India's most notorious man-eating tigers and leopards — including the Champawat Tiger and the Rudraprayag Leopard. His books, including Man-Eaters of Kumaon (1944), are considered classics of natural history writing. Remarkably, Corbett later became one of India's first and most passionate conservation advocates — Corbett National Park, India's oldest national park and a key tiger reserve, is named after him.
