The tiger, a large feline mammal of the Felidae family, has light yellow or brownish fur with black stripes, a round head, short ears, and a prominent white spot; it spans nine subspecies, each differing significantly in size and morphology.

The giant Siberian tiger reaches a length of 3.7 meters and weighs 423 kilograms, while the smallest, the Sumatran tiger, measures 2.34 meters and weighs 136 kilograms.

Tigers are typical mountain-dwelling creatures in tropical rainforests, evergreen and deciduous broadleaf forests, and mixed coniferous and broadleaf forests. They mostly roam alone, only coming together during the breeding season. They lack fixed dens and typically forage in forested areas, displaying exceptional swimming abilities.

Primarily active at dusk, they tend to rest during the day unless disturbed. Tigers cover significant territories, ranging several kilometers in the north and shorter distances in the south where food is more abundant.

Breeding occurs between November and February; their vocalizations can carry up to 2 kilometers. Gestation lasts around 105 days, yielding 1 to 5 cubs, typically 2, weighing about 1 kilogram at birth. Cubs remain with their mother for 2-3 years, during which she does not mate again, resulting in a 2-3 year reproductive cycle for females. Tigers reach sexual maturity at three years for females and later for males, with an average lifespan of 20-25 years.

Due to human hunting and habitat fragmentation, tigers have become critically endangered and are an endangered species on the Red List. Global wild tiger populations were reported as 3890 individuals in 2016, with many populations numbering fewer than 100. This decline has led to a loss of genetic diversity and quality, posing severe threats to tiger species.

Tigers, solitary except during breeding, mark their territories using scent glands, urine, or claw markings on trees. Males might share domains with multiple females, but female parts usually don't overlap. Cubs are raised solely by the mother, and while they leave to hunt, she regularly returns to check on them. Females may repel a mate after mating and rear the cubs alone.

Tigers in the wild stand as guardians of the forests, epitomizing elegance and strength. Yet, their existence faces escalating threats, teetering on the brink of extinction due to habitat destruction and hunting. We must collectively strive towards preserving these majestic creatures, safeguarding ecological equilibrium, and ensuring future generations can share this planet with these awe-inspiring wild beings.

Only by protecting their habitats and allowing them secure lives can we continue to marvel at these majestic felines, letting them roam freely in the natural world.
