Siberian Tigers are mostly found in Siberia and Manchuria. At one time they could also be found in China and Korea though their numbers have sharply declined in those areas due to illegal poaching. Siberian Tigers are an endangered species.
Siberian Tigers are the largest of cats weighing up to 850 lbs and are up to 10-12 feet in length. Siberian Tigers have an amazing ability to jump and can jump up to 23 feet.

Taxonomic proposals are just that: proposals. You don't have to say yes to every taxonomic proposal. The use of the domain is mainly to give recognition to the difference between eubacteria and archaebacteria. Since Siberian tigers are eukaryotes, not bacteria, we can safely ignore the domain system. Instead one can subscribe to the Empire system, with Prokaryota and Eukaryota as the two empires. Basically, the 3 domain system takes the 2 empire system and split Prokaryota into Arhaea and Bacteria. As Ernst Mayr points out, bacteria have more in common with one another than they do with the eukaryotes, so the 3 domain system is perhaps excessive splitting. Regardless of whether life on earth is classified as 3 domains or 2 empires, Siberian tigers will still be part of Eukaryota.
