Siberian tiger

The Siberian tiger has a fire-like gaze, a thick and perfect body, strong muscles on the back and forelimbs undulating in motion, huge limbs pushing forward, smooth and quiet, as if gliding in the jungle. It also has a sharp serrated hook claw, 5 very sharp tiger claws that protrude when used, retract the claw sheath when not in use to avoid rubbing the ground when walking. Siberian tigers are introverted, suspicious and fierce, agile, and haunt the jungle, making it difficult for ordinary people to witness wild Siberian tigers.
