it fights to the death
Not an intelligent question.
Adults have only humans for enemies.
Man,
Poachers, hunters and loggers. Boars and Elephants also are a danger to the Siberian Tiger.
A Siberian tiger would jump on its back and then try to bite it in the throat, but the rhino's head and horn will knock the tiger out. If the Siberian tiger managed to claw or bite, the rhino's thick hide will protect itself, and the rhino will get angry.
Hunters and pouchers
Humans are their main enemies, because humans hunt and sell their fur for money.
A young one, but not an adult one since the muskox has such thick fur to protect itself from blizzards, wolves, and polar bears. The muskox has a weight advantage of 880 pounds, whereareas the siberian tiger has a weight of 600 to 650 pounds. The muskox's weight would make it very hard for the siberian tiger to bring it down. Also, if the siberian tiger gets near the muskox, the muskox could kill it with a gore of a horn or a headbutt.
They leave a heavy scent, so that their predators and other animals don't come onto their territory.
No
