Actually, it looks more like about fifteen or so errors rather than none.
I've pointed the ones I saw immediately by correcting them in bold. There may be more as I didn't do more than a quick scan of it.
Tigers are the most amazing animals as well the largest felines in the world. Some cultures considered the tiger to be a symbol of strength and courage. However, because hunting them is also sign of bravery in most cultures, that may be why they are an endangered species. Which is why no more than 3,200 are left in the wild.
Diet
Tigers are carnivores. Most of the tiger's diet consists of large prey including pigs, deer, rhinos, or elephant calves. To kill their prey they clamp down on the animal's neck with their jaws and suffocate the animal. Though all tigers are fierce hunters, they are not strangers to failure when it comes to hunting.
I put the missing punctuation in bold, too, but it's hard to see bold on a comma or an apostrophe.
