As 你 probably know, cheetahs and leopards look very similar and many people mistake cheetahs for leopards 或者 the opposite. Look at two 图片 of a leopard and a cheetah, then you'll see that they're very different from each other.
1. Cheetahs are much 更多 lanky, having a thin stomach for easier running. But leopards have 更多 muscles, though I may not know much about leopards, but I'm guessing it's for hunting purposes.
2. Cheetahs have a larger chest because they have extra large lungs and 心 so they can withstand their large bursts of energy.
