There are plenty of fearsome predators walking the face of the planet, but few are as scary, dangerous and, at the same time, interesting as crocodiles. These gigantic reptilians are deadly creatures that hide a lot of secrets and deserve to be discussed. So, let’s do just that. Let’s talk about 15 Unbelievable Facts About Crocodiles.
- Crocodiles are the biggest reptiles on Earth. They can grow up to 6.17 meters (20 feet 3 in) and can weigh more than a ton.
- They can be found in nature in all inhabited continents except for Europe.
- For the longest time, crocodiles were considered to be carnivores (meaning they only eat meat), but recent studies have found out that they also seem to consume fruit,often in large amounts, making them omnivores. Other than that, they mostly consume mammals, birds, and fish.
- You ever look at a crocodile and think:”wow, they look just like dinosaurs”? Well, crocodiles are actually very close relatives to dinosaurs and existed during dinosaur era and actually haven’t evolved as much as most animals did in all this time, largely because they have almost always been at the top of the food chain and didn’t really need to evolve new features to survive.
- Crocodiles have valves at the back of their throats, which allows them to keep their jaws open underwater.
- They also live pretty long. Crocodiles have an average lifespan of 30 to 40 years, while the larger ones can live up to 60 to 70 years. There’s also reports of some crocs living to 100 years, but that is not fully confirmed.
- Crocs usually have about 60 to 110 teeth at a time and if they lose one, there’s already another one growing as a replacement. They can replace each of their 80 teeth up to 50 times over their lifetime. They can lose up to and slightly above 4000 teeth in their lifetimes. Now that’s a lot of teeth!
- The first crocodiles appeared about 250 million years ago, at the same time when dinosaurs did, and they were significantly larger than today’s crocodiles.
- Crocodiles jaws can produce about 5,000 pounds or 2267 kilograms of pressure per square inch – more than ANY animal living today. Contrast this to average human bite force which is around 100 pounds or 45 kilograms per square inch. Their jaws are like hydraulic presses. That’s even 10 times stronger than the bite force of great white sharks.
- Although their jaw clenching muscles are incredibly strong, their jaw opening muscles aren’t. In fact, they’re so weak, that their jaws can be held shut with rubber bands or average person’s hands.
- People often have troubles differentiating between crocodiles and alligators. An easy way to do so (although possibly dangerous) is to look in the insides of their mouths. If you can see their upper teeth – those are crocodiles, because alligators have depressions in their upper jaw hiding their upper teeth from plain sight.
- Crocodiles have an incredible night vision and they are deadly nocturnal hunters.
- They are amazing swimmers. They can reach speeds of 35 kilometers or 22 miles per hour.
- Crocs are cold-blooded. Literally. They are cold-blooded animals whose bodies temperatures depend on their environment and they have naturally slow metabolisms, that make them slow, but also capable of surviving without food for long periods of time. They actually can live for many months on a single meal.
- Crocodiles can hold their breath underwater for about an hour, making them even more dangerous.
So, as you can see, crocodiles are incredibly dangerous reptiles that are cold-blooded in every way possible. Mother nature made sure that they are as dangerous and energy efficient as possible. So, just be careful, if you ever find yourself around them. And that concludes 15 Unbelievable Facts About Crocodiles.
