It may be tempting to think of these big reptiles as totally alien to us humans, but the truth is they live a lot like you do: they grow up quickly, reach full size, gradually get older and weaker, and eventually die (after what was hopefully a long – but not endless – life).
SCOTTBURH, South Africa — Henry is kept at the Crocworld Conservation Centre in KwaZulu-Natal, South Africa. The crocodile arrived at the nature preserve in 1985, when he was already 85 years old.
The oldest crocodiles appear to be the largest species. C. porosus is estimated to live around 70 years on average, with limited evidence of some individuals exceeding 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.
But the crocodile family tree also forked about 100 million years ago, with the appearance of the enormous Sarcosuchus, which measured about 40 feet long from head to tail and weighed about 10 tons. There was also the slightly smaller Deinosuchus, which was about 30 feet long.
Well, crocodiles share a heritage with dinosaurs as part of a group known as archosaurs (“ruling reptiles”), who date back to the Early Triassic period (250 million years ago). The earliest crocodilian, meanwhile, evolved around 95 million years ago, in the Late Cretaceous period.
Coelacanths, first swam in the ocean about 400 million years ago and were believed to be extinct until one was caught off South Africa in 1938.
Unlike many other animals on this planet, crocodiles and alligators have no finite life span. Instead, they continue to live and grow unless affected by their environment through a lack of food, disease, accidents, or another large predator. Instead of aging biologically, alligators continue to simply grow in size.
Today's crocodiles are not holdovers that have gone unchanged since the Jurassic, but are one expression of a great, varied family that's been around for over 235 million years. More than that, crocodiles are still evolving—and faster than they have at other times in their family's scaly history.
There are two main reasons. First, crocodiles can live for a very long time without food. Second, they lived in places that were the least affected when the asteroid hit Earth.
Crocodiles have cold blood
Neither of these factors was efficient during the cold and dark conditions following the Yucatan meteor impact. Crocodiles have cold-blooded metabolisms, which means they were able to live for long periods of time in severe darkness, cold, and with very little food.
To date, there's only one species that has been called 'biologically immortal': the jellyfish Turritopsis dohrnii. These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle.
The crocodile's immune system is much more powerful than that of humans, preventing life-threatening infections after savage territorial fights which often leave the animals with gaping wounds and missing limbs.
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.
Bowhead whales can live more than 200 years–making them one of the longest-living mammals on Earth. Bowhead whales live in the chilly Arctic and subarctic waters year-round.
The oldest dog living is Gino Wolf (USA, b. 24 September 2000), who is 22 years 52 days as verified in Los Angeles, California, USA, on 15 November 2022. Gino was adopted by Alex Wolf in Boulder, Colorado, in 2002.
The story: In eastern California, a Great Basin bristlecone pine known as Methuselah has long been considered Earth's oldest living thing. According to tree-ring data, it is 4,853 years old — meaning that Methuselah was well established by time ancient Egyptians built the pyramids at Giza.
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.
Today's birds are the last of the dinosaurs, descendents of ancestors that didn't just survive this mass extinction, but evolutionarily exploded into thousands of species distributed around the world.
Crocodiles relatives are believed to have existed either before dinosaurs or right when dinosaurs first appeared! Crocodile ancestors date back 240 million years to the Triassic period, that's the same era that dinosaurs first began to flourish.
The research, published in the Journal of Vertebrate Paleontology, found that the Deinosuchus, a lineage of the giant crocodilians from North America, grew up to 33 feet long and “was the largest carnivore in its ecosystem,” in the late Cretaceous period about 75 to 82 million years ago.
Crocodiles, dinosaurs and winged pterosaurs all descended from the archosaur. But only the crocodile survived a post-meteor world, and its survival could be due to a complex system of senses and other traits that allowed it to become an apex predator.
There are two main reasons. First, crocodiles can live for a very long time without food. Second, they lived in places that were the least affected when the asteroid hit Earth.
Flatworms, nematodes, and cnidarians (jellyfish, sea anemones, and corals) do not have a circulatory system and thus do not have blood. Their body cavity has no lining or fluid within it.
