A male crocodile lived to an estimated age of 110–115 years in a Russian zoo in Yekaterinburg. Named Kolya, he joined the zoo around 1913 to 1915, fully grown, after touring in an animal show, and lived until 1995. A male
Crocodiles live much longer than similar-sized land mammals, sometimes living up to 100 years.
Crocodiles can live up to 75 years. Crocodiles can live up to 70 years in the wild, with the Saltwater crocodile being the longest living species. However, crocodile lifespans among species range from 25 to 70 years. Crocodiles in captivity have been known to reach 100 years old.
Freshie, a saltwater crocodile that lived to 140 years old.
Today's crocodiles, which in scientific terms are part of the Crocodilia Order, first appeared about 95 million years ago. That was 30 million years before dinosaurs went extinct.
Kaprosuchus: 100-95 million years ago, nicknamed “boar crocodile,” similar in size to modern Saltwater crocodiles, 20 feet long and 2000 lbs., fossils found in Africa. Kaprosuchus can have lengths of up to 20 feet.
The crocodile was about 2 to 2.5 meters in length. It was found in a massive, shattered boulder. Early neutron imaging scans of one rock fragment from the boulder detected bones of the small chicken-sized juvenile dinosaur in the gut. The species of the dinosaur is yet to be formally identified.
A croc's metabolism is so evolved that its body uses and stores nearly the entirety of the food it consumes. This is one reason why larger crocodiles can go for over a year without eating a meal.
The age record might belong to a three-metre (9ft) crocodile that lived in captivity in Russia for over a hundred years before dying two decades ago.
Dubbed "SuperCroc" by the media, Sarcosuchus looked and behaved like a modern crocodile, but it was a whole lot bigger--about the length of a city bus and the weight of a small whale!
Crocodiles have been dubbed the 'ultimate survivors'. Having arisen some 200 million years ago, they have outlived the dinosaurs by some 66 million years. They have also seen off two ice ages. Even humans, the most fearsome predators ever to stalk the Earth, have failed to force any species into extinction.
How Long Can Snails Sleep? Certain land snails can sleep for up to three years in hibernation or estivation. Yes, it's true!
Tardigrades can live years without food. These are their adaptations to extreme climatic conditions in their habitat for survival. Animals like Emperor penguin, Tardigrade do not eat food in extreme climatic conditions and undergoes a dormant stage.
Immune system: The crocodile has an optimal immune system. It is almost completely immune to infection with viruses and bacteria (natural antibiotics), able to eat rotting carcasses and swim in contaminated water without being affected.
Deinosuchus (/ˌdaɪnəˈsjuːkəs/) is an extinct genus of alligatoroid crocodilian, related to modern alligators and caimans, that lived 82 to 73 million years ago (Ma), during the late Cretaceous period.
It is a previously unknown species of crocodile. But that was not all, the crocodile seemed to have a rather full and unexpected meal before its death. Because in his stomach, the paleontologists also found the remains of a dinosaur a little bigger than a chicken.
Crocodiles are known for their short legs, scaly skin and mighty snap. However, new research suggests the reptiles may have once walked on two hind legs! Scientist believe an ancient species of crocodile which is thought to have lived between 110 and 120 million years ago got around on two legs just like dinosaurs.
The Reptiles Haven't Changed in 200 Million Years. Crocodiles are large reptiles with scaly complexions and menacing marble-like eyes. If we were to go back in time 200 million years, we would find that the crocodile's appearance would be unchanged.
Relatives of crocodiles have been around for an extraordinary length of time, their fossil remains having been found in rocks from the early Jurassic period, around 200 million years old. Stranger still, these crocodiles from the age of the dinosaurs often look surprisingly like the crocodilians of today.
Australia is home to two species of crocodiles, the Estuarine Crocodile and the Freshwater Crocodile. Both belong to the reptile family Crocodylidae (the 'true crocodiles'), members of the sub-class Archosauria.
Known as Deinosuchus, which means "terrible crocodile" in Greek, this lineage of semiaquatic reptiles certainly lived up to its name. They were among the biggest predators in their watery North American habitats, where they lived between 75 million and 82 million years ago.
They react differently when external stimuli are applied while sleeping and while awake. But the bullfrog, Lithobates catesbeianus show the same reaction in both situations. This indicates that bullfrogs do not sleep. Lithobates catesbeianus is an animal that cannot sleep.
