The largest species of cat in the world is the Siberian tiger (Panthera tigris altaica), which can weigh up to 660 pounds (300 kg) and measure over 10 feet (3 meters) in length, including its tail. Native to the forests of eastern Russia and parts of China, Siberian tigers are known for their beautiful orange coats with distinctive black stripes. They are solitary and territorial animals that primarily hunt large prey such as deer and boar. Due to poaching and habitat loss, Siberian tigers are classified as endangered, making conservation efforts crucial to their survival in the wild.
