An inaccuracy very commonly mentioned is that Siberian or Amur Tigers are the largest tiger subspecies when in fact, they're no bigger than Bengal Tigers.
Amur Tiger Ecology
"Amur tigers are often considered the largest of the tiger sub-species, although they are in fact about the same size as the Bengal tiger. An adult male usually reaches a body length of 2 meters, with his tail adding another meter. Average weight for males is 160-190 kg, while females are smaller, weighing in at 110-130 kg. The largest male captured for scientific research under the Siberian Tiger Project weighed in at 206 kg."
