They Can Breathe Underwater
If you thought saltwater crocodiles had a fault, think again. These guys can breathe underwater. So, not only can they survive on land, like humans, but underwater… unlike humans. This makes them unstoppable, should an apocalypse come. They already survived one apocalypse, so they might be able to survive another. It’s said that “the saltwater crocodile has a valve at the back of its throat that allows it to open its mouth while breathing through its nostrils without ingesting water” (Sport Diver). If only humans could do this, then we may have saltwater crocodiles beat. But it looks like they’re the more powerful species when it comes to survival and fighting skills.
