We have been introduced to only two of the Bijuus. There are 9 tailed demons in Naruto called Bijuus. They have immense power and great source of chakra. The person in which these beasts are sealed is called a Jinchuuriki.

Gara and Naruto are one of them. Gara has Shukaku, which is one tailed racoon like creature and Naruto has Kyuuni, the nine tailed fox.

Where are the rest of the beaasts and what are they?

Could a Jinchuuriki survive if the Bijuus is taken from him?
