Cassius is the world's largest captive
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.
The Saltwater Crocodile in Australia's Northern Territory is the largest reptile in the world, and has remained one of the deadliest predators for more than 100 million years.
Guinness World record website also says that Cassius, the Australian saltwater crocodile, measured 17 ft 11.75 in. Australian saltwater crocodiles can live for more than 100 years and can weigh more than 1 tonne.
The movie Primeval is actually about the monstrous crocodile. Some rumors suggest 'Gustave' died in 2019. But there is no photographic evidence, and no carcass ever got recovered. 'Gustave' is a Nile crocodile that is considered the most dangerous crocodile.
Although most attacks are not reported, the Nile crocodile is estimated to kill hundreds (possibly thousands) of people each year, which is more than all other crocodilian species combined.
The Mary River in the Northern Territory has 15 crocodiles per km, making it the most densely populated river! The temperature of the egg determines the sex of the animal.
Australia has saltwater crocodiles (Crocodylus porosus) which are bigger than the Nile crocodiles (Crocodylus niloticus). The saltie is the world largest living reptile, growing to an average size of 6.7 m and weight around 2000 kgs.
There are more saltwater crocodiles in the NT than Queensland and Western Australia (WA). A large proportion of the coastal region of the NT is an ideal habitat for saltwater crocodiles, particularly the big, productive coastal wetlands and rivers.
Tarcoles River - highest populations of crocodiles in world - 25 crocs per square kilometer - Picture of Jose's Crocodile River Tour, Tarcoles - Tripadvisor.
"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.
Experts say while the crocodile population has stabilised, crocodiles are getting bigger on average each year as more of them reach maturity. NT government monitoring of Top End rivers has found a shift in the total weight of crocodiles observed.
The Nile crocodile is the largest crocodilian in Africa, and is generally considered the second-largest crocodilian after the saltwater crocodile.
Nile Crocodile (Crocodylus niloticus)
Although adults vary in size, most grow to reach 16.5 to almost 20 feet (roughly 5 to 6 meters) in length. The species easily claims the title of the most-dangerous crocodilian, since it is widely thought to be responsible for more than 300 attacks on people per year.

While they won't be found in the middle of the ocean, it is important to note that they can still be found in the ocean. To say that they “swim” in the ocean would be a stretch. In certain bodies of water like rivers, etc.
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.
"The Proserpine River has the highest density of crocodiles anywhere in Queensland," he said.
A FRESHWATER crocodile has been found in the Murray River near the New South Wales-Victoria border, thousands of kilometres south of home.
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.
Tiger Sharks Eat Crocodiles
Saltwater crocodiles are among the largest growing crocodiles and the most ferocious. Despite this, they are often prey for tiger sharks. Others, such as bull sharks, are also known to hunt crocodiles. But tiger sharks remain the top predator – winning fights 9 out of 10 times.
Humans can be faster on land than crocodiles, but crocodiles are much faster in water. The average human being can run at speeds of 6.5 and 8 mph, but they can reach 27.5 mph during a full sprint. Meanwhile, crocodiles can move at speeds of about 3 to 5 mph on land, but they can't maintain that speed for very long.
Stephen Robert Irwin (22 February 1962 – 4 September 2006), known as "The Crocodile Hunter", was an Australian zookeeper, conservationist, television personality, wildlife educator, and environmentalist. Irwin grew up around crocodiles and other reptiles and was educated regarding them by his father Bob.
Back in July 1957, Australia's largest known crocodile, 8.64 metres long, was killed with a single shot on the banks of the Norman River by a Polish immigrant Krystina Pawlowski. The shot made her a worldwide celebrity and earned her the nickname One Shot along with a place in the Guiness Book of Records.
