The most significant differences between a Nile crocodile and a saltwater crocodile are their size, color, and preferred habitats. 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.
1. Saltwater crocodiles are the largest crocodile species in the world, and the largest living reptile in the world. 2. Male saltwater crocodiles have been recorded at lengths of 23 feet (7 m) and weights of 2,205 pounds (1,000 kg).
The Australian saltwater crocodile is one of the most aggressive and dangerous crocodiles. It is also the largest living reptile, exceeding the Komodo dragon in size. Sexual dimorphism (difference) is present in this species, with the females normally growing to more than 3 metres and males normally up to 6 metres.
The Nile crocodile is the largest crocodilian in Africa, and is generally considered the second-largest crocodilian after the saltwater crocodile.
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.
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.
Cassius, the 5.48m giant holds the Guinness World Record for being the largest croc currently in captivity. Housed on Green Island in Far North Queensland, he weighs more than one tonne and is believed to be more than 110 years old. The world record was previously held by Lolong in the Philippines.
The largest species of crocodilian in the world is the estuarine or saltwater crocodile (Crocodylus porosus), which ranges throughout the tropical regions of Asia and the Pacific, including the northern coast of Australia.
Crocodiles are the larger species and fully-grown will be up to a metre longer than even large alligators. They are also a lighter colour and have long, v-shaped snouts. This v-shaped snout also gives crocodiles a rather toothy grin. In fact, crocodiles are unable to close their long snouts to hide their teeth.
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. Unfortunately, he died of congestive heart failure in February 2013. The largest crocodile alive is Cassius who is about 100 years old.
Saltwater crocodiles are longer than most anacondas and heavier, too! An anaconda is a snake while a crocodile is closer in morphology to a lizard, even though they are not directly related to them. Crocodiles are heavier and faster than anacondas both on land and in the water.
Brien said aggression in saltwater crocodiles is “hardwired from hatching” but there is no clear explanation why the species is so short-tempered. One theory is that competition with other crocodiles, combined with its sheer size, has instilled the aggression.
"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.
“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.
There are thought to be around 200,000 Saltwater Crocodiles in Australia, with the most found in the areas surrounding Darwin and the Mary River. Over the years, they have been hunted for their skins and have almost been brought to extinction on a number of occasions.
Antarctica and Europe are the only continents without native species of crocodile.
"Today what we see is crocodiles restricted to northern Australia and the coast because the inland of Australia doesn't have much or any permanent water, so crocs that used to inhabit parts of the Murray-Darling Basin or the Lake Eyre basin couldn't persist there anymore because the water is so intermittent," Dr ...
Where are crocodile attacks most common? Most crocodile attacks occur in sub-Saharan Africa. There are large concentrations of aggressive Nile crocodiles along major waterways that thousands of people use daily.
The Murray River is way too far south for saltwater crocodiles to go near. The water is too cold for them – it's the same reason there are no crocodiles in Sydney and no crocodiles in Brisbane.
Crocodiles have been known to be as far south as the Mary River in Gympie. This is only about 167km from Brisbane and only 52km from the Great Sandy National Park. More astonishingly, this is a whopping 449km away from the northern points of Queensland where they are typically found.
Croc country (considered to be typical crocodile habitat) begins at the Boyne River south of Gladstone, and extends northward, up the east coast and across Far North Queensland.
But despite their size and strength, there are animals that do prey on them. Man appears to be their biggest predator. Big cats like leopards and panthers sometimes kill and eat these big reptiles. Large snakes can also do a lot of damage to alligators and crocodiles.
A crocodile would win a fight against a gorilla. Most of the fights would begin in or near water, and a gorilla doesn't stand a chance in that scenario. If a crocodile bit and dragged the gorilla into the water, then it's a simple victory.
A fully grown saltwater crocodile would win a fight against the largest bears. Size matters in these fights and crocodiles have that advantage. Bears are undoubtedly strong, but they've never faced anything like a crocodile to know their weaknesses.
