Which Is Bigger: A Siberian Tiger or a Bengal Tiger?

The Siberian tiger is bigger than the Bengal tiger. Siberian tigers can reach lengths of up to 3.7 meters (12.1 feet) and weigh as much as 423 kg (about 933 pounds), whereas Bengal tigers typically grow to about 3.2 meters (10.5 feet) in length and weigh approximately 295 kg (about 650 pounds).

The size difference between these two subspecies of tiger can be attributed to their respective habitats and adaptations. The Siberian tiger, also known as the Amur tiger, inhabits the cold-climate forests of far-eastern Russia and northeastern China, where its larger size and thick fur help in conservation of heat and insulation against the snow. On the other hand the Bengal tiger roams the hot and humid forests and wetlands of India, Bangladesh, Bhutan, and Nepal, where a slightly smaller size is more advantageous for navigating dense vegetation and swamps.

Both the Siberian and Bengal species of tiger are endangered, but their population numbers differ significantly. There are fewer than 600 Siberian tigers left in the wild, while the Bengal tiger population is estimated to be between 2,000 and 2,500. Despite their differences in size and population, both subspecies face similar threats, such as poaching and habitat loss, which continue to endanger their survival.
