The largest cat species in the world is the Siberian tiger (Panthera tigris altaica). Native to the forests of eastern Russia, the Siberian tiger can weigh up to 660 pounds (300 kg) and reach a length of nearly 10 feet (3 meters), including its tail. This majestic animal is known for its distinctive orange coat with black stripes, which provides effective camouflage in its natural habitat. Unfortunately, due to habitat loss and poaching, the Siberian tiger is classified as endangered. Conservation efforts are underway to protect their populations and preserve their natural ecosystems.
