Well, letâs talk size first. Tigers are heavier, weighing up to 800 pounds to the lionâs 550. But the two cats arenât so different in size. You might remember from high school health class that muscle weighs more than fat, which helps explain the tigerâs extra pounds. So it seems that the tiger would have a physical advantage over the lion.
Tigers DO live in the 'jungle', so are harder to find. In the wild, the two do not meet, so there was always a question as to who was the stronger. The lion LOOKED bigger, so was assumed to be stronger, but lions and tigers have different muscle structure, since lions run more in life, and tigers climb more.
