How long can saltwater crocodiles stay in saltwater?
Large saltwater crocodiles can stay underwater for at least one hour because they can reduce their heart rate to 2-3 beats per minute.
A large saltwater crocodile has been caught on video with a smaller freshwater crocodile in its jaws.
"Optimal climate conditions (such as in some places in Australia) with few cold periods make it easier for the crocs to grow larger," Groh said. Salty males tend to be much larger than females, Drumheller-Horton said, though age is a big factor in how big these beasts can grow.
Freshwater crocs have a narrow snout and a single row of four large scutes (bony plates) right behind their head. Salties have a broader snout and no scutes. Freshwater crocs measure up to three metres long, while male saltwater crocs can grow to a whopping six metres and weigh in at more than 1000 kg!
Predators of Crocodiles include humans, large felines, and birds of prey. What is an interesting fact about Crocodiles? Crocodiles have changed very little in 200 million years!
The short answer is yes. “Most crocodiles can achieve 12–14kph for short periods,” says crocodile specialist Adam Britton, “which is slower than a fit human can run. So if you're in reasonable shape, you could definitely outrun a croc.”
Saltwater crocodiles may occur in any salt or fresh water within their range.
A great white shark would win a fight against a saltwater crocodile. These deadly creatures are incredibly powerful, but the great white shark has an amazing advantage in the water. Not only would this animal probably notice the crocodile first, but it also has the speed to land a devastating attack.
Saltwater crocodiles are larger than Nile crocodiles on average, weighing between 400 and 1,150 pounds, while the Nile crocodile averages between 500 and 910 pounds.

Can you outrun a crocodile?
But how quickly can they run? Most crocodiles can achieve speeds of around 12 to 14 kph for short periods, which is somewhat slower than a fit human can run. Don't believe the hype - if you're reasonably fit, you can definitely outrun a crocodile!
“It is unlikely,” Klepper said. “We are unaware of any successful hybridization between Nile and American Crocs.” But aren't the reptiles cousins? “It is highly improbable that this croc would mate with the wild native crocodile because of dissimilar habitat and behavior,” Klepper answered.
The study revealed that baby saltwater crocodiles have the same level of aggressiveness as adults who spend their entire lives in the wild. According to biologist Matthew Brien, who led the research, “The saltwater crocodile has a reputation for being one of the most aggressive species in the world as an adult.”
Freshwater crocodiles are grey or olive-brown with ragged dark mottling. A freshwater crocodile can be distinguished from an estuarine crocodile by its narrow snout and evenly shaped and sized needle-like teeth.
But in many cases the crocodilians were the prey, from great white sharks preying on American crocodiles in Colombia, to tiger sharks eating estuarine crocodiles in Australia.
A hippo would win a fight against a crocodile. Although crocodiles are large, powerful creatures, they cannot kill a fully grown hippo. Hippos are large, roundish animals that are much taller than crocodiles. The only place they would be vulnerable to attack is their legs.
Bears have better senses than crocodiles, and they are stronger overall than crocodiles. Also, bears are faster on land than crocodiles. Both creatures rely on their bites to finish off enemies. Of course, their bodies are very different as well.
The ultra-tough skin, bone-like scales, and strength of these water animals make people believe they are impervious to bullets. Though a large, fully-grown crocodile could survive a shot from a smaller weapon, multiple gunshots can take any crocodile down, regardless of its size.
If a crocodile heads your way, run away in a straight line. The myth about moving in a zig-zag motion is just that—a myth. Crocodiles can move at 10 miles per hour, so remove those flip flops so you can run faster.
The crocodile jaw has very little opening strength, though; a crocodile's mouth can be held shut with just a rubber band. In addition to their strong jaws, crocodiles have very keen hearing.
Can Crocs be submerged in water?
In fact, crocodilians can spend hours underwater without coming up for a breath of air.
Mr Lever said saltwater crocodiles cannot drink saltwater, they have to drink fresh.
| Rank | Animal | Bite Force |
|---|---|---|
| 1 | Great White Shark | 4,000 PSI |
| 2 | Saltwater Crocodile | 3,700 PSI |
| 3 | Nile Crocodile | 3,000 PSI |
| 4 | American Alligator | 2,980 PSI |
A crocodile would win a fight against a Komodo dragon. Crocodiles are simply too large and too powerful for a Komodo dragon to fight back against. One likely outcome would be the crocodile waiting for the Komodo dragon in water and dragging it beneath the waves to suffer a brutal death.
A crocodile would beat an anaconda in a fight. A fully grown crocodile is simply too big and strong for an anaconda to kill. Even in an ambush situation, the anaconda would struggle to wrap enough of its body around the crocodile to inhibit its movement and crush it.
#6: Crocodiles
What is most likely to kill an elephant is the crocodile biting the elephant's trunk off. The elephant may then die as a result of not being able to eat and drink properly, or even breathe. On the other hand, a crocodile is most likely to kill a baby elephant and is most successful in its watery turf.
The hippo is at least twice the size of the saltwater crocodile and has teeth that are enormous and more deadly. The only thing the saltwater crocodile can do is plague the hippo at its feet. Since the hippo is taller than the saltwater crocodile, it could pick it up with its teeth, bite, stomp and fling the crocodile.
Interestingly, they are two creatures that have not changed much in millions of years because they're already perfect at what they do: eat other animals. Being that crocodiles live in many places around the world but need to stay close to land for food, the chances of a crocodile vs shark match ever happening are low.
Erickson and colleagues put all 23 living crocodilian species through an unprecedented bite test. The "winners"—saltwater crocodiles—slammed their jaws shut with 3,700 pounds per square inch (psi), or 16,460 newtons, of bite force.
Based on fossil evidence, the longest crocodile ever to live was a Sarcosuchus imperator, who measured 40 feet long and weighed 17,600 pounds. The largest one ever officially measured was Lolong, who was a saltwater crocodile who measured 20 feet three inches long and weighed 2,370 pounds.
Who would win alligator or crocodile?
Crocodiles win the fight because they're bigger, stronger, and more aggressive than alligators.
The green anaconda will eat anything it can catch and overpower including rats, fish, birds, tapirs, capybaras, deer, warthogs, caimans, other snakes and reptiles, and even crocodiles.
In the wild, an older, weaker croc is more likely to face starvation or competition, but even in captivity, the animals inevitably die.
Pocho (around 1950–1960 – 12 October 2011) was a Costa Rican crocodile who gained international attention for his relationship of over 20 years with Gilberto "Chito" Shedden, a local fisherman who found Pocho dying on the banks of the Reventazón River and nursed him back to health.
Their armor-like skin is near impenetrable—no amount of kicking, punching, or other fighting can pierce it—and their heads are solid masses of bone. According to Chris Packham, wildlife presenter and crocodile fan, “there are no weak points” across their bodies So what do you do?
"Saltwater crocs have the strongest recorded bite force of any animal on the planet — [the] kind of force can easily crush a human skull," Frost said.
In fact, crocodilians can spend hours underwater without coming up for a breath of air. I have personally observed a female saltwater crocodile spend nearly two hours submerged. So how are crocodilians (which include every species of crocodile, alligator, caiman and gharial) able to perform this amazing feat?
“[The crocodiles] can survive for long periods in salt-water without eating or drinking, so by only travelling when surface currents are favorable, they would be able to move long distances by sea.
Saltwater crocodiles are found in both tidal and freshwater areas. Saltwater crocodiles are naturally found long distances upstream into areas dominated by, and considered typical for fresh water crocodiles. Fresh water crocodiles are only sometimes found in tidal, saline areas.
Crocodiles do not live in the ocean. Because they are semi-aquatic, they still need access to land where their food sources are found. While they can survive for extended periods of time without food, they still need access to their food. With this in mind, they are mostly found in rivers, estuaries, and even lakes.
Can I outrun a crocodile?
But how quickly can they run? Most crocodiles can achieve speeds of around 12 to 14 kph for short periods, which is somewhat slower than a fit human can run. Don't believe the hype - if you're reasonably fit, you can definitely outrun a crocodile!
Crocodiles in captivity have been known to reach 100 years old. What's most interesting about crocodiles is that they don't die of old age. They do not die from biological aging. Instead, they continue to grow and grow until some external factor causes them to die.
Be sure to run away from the water to avoid running into the jaws of more crocodilians. Forget the conventional wisdom about running in a zig-zag pattern to escape; the quickest way to escape an alligator or crocodile is in a straight line. This is because humans (and other animals) run faster in straight lines.
Keeping every factor in mind, we can say that a crocodile does not have a bulletproof body, but they can deflect or survive many powerful shots due to the thick layer of skin and bony scales. However, some well-placed shots on their vital parts can kill them immediately.
Sadly for mad scientists everywhere, the answer to this question is no. According to Owlcation, both alligators and crocodiles fall into the "Crocodilia" order, but they're not related closely enough to interbreed.
1. Saltwater crocodiles are the largest crocodile species in the world, and the largest living reptile in the world.
Erickson and colleagues put all 23 living crocodilian species through an unprecedented bite test. The "winners"—saltwater crocodiles—slammed their jaws shut with 3,700 pounds per square inch (psi), or 16,460 newtons, of bite force.
Crocodiles exist both in freshwater and saltwater, whereas alligators prefer freshwater environments. The Florida Everglades is the only place on earth in which both alligators and crocodiles coexist.
The largest living reptile documented by science is the saltwater crocodile. They ambush their prey before drowning and swallowing them whole. The saltwater crocodile is one of the only crocodiles able to regularly kill and eat sharks.
