Max weight: 2,200 pounds
Bottom line: Captain Hook should probably cross “African safari” off his bucket list. Nile crocodiles are the second-largest reptiles in the world, coming right behind the saltwater croc.
The biggest Nile crocodiles are more than 20 feet in length. They look like living dinosaurs, and they’re not too far off. Their primitive brains and cold-blooded metabolisms are throwbacks to earlier lifeforms, and they haven’t changed much for thousands of years.
They employ surprisingly advanced ambush tactics to catch their prey. If a croc looks your way, run. They can bite down with a force of 3,700 pounds per square inch, more than triple the pressure of a lion bite.
Don’t stick your arms out of tour boats, and if it comes down to an attack, go for their eyes. It’s just about the only place on their body that isn’t covered in armor.
