Largest Reptile in the World?

If youre asking yourself what the worlds biggest reptile is, then the answer is a bit complicated, because we have to make a significant distinction do you want to know the largest living reptile, or the largest reptile ever? For the former, the answer is pretty straightforward: the saltwater crocodile takes the crown, with a maximum documented weight of 2 tons. As for the latter, its probably (though we dont know for sure) a dinosaur called Amphicoelias fragilimus measuring 58 meters (190 ft) in length and weighing 122 metric tons.

The saltwater crocodile, Crocodylus porosus is believed to have a direct link to similar crocodilians that inhabited the shorelines of the supercontinent Gondwana 98 million years ago. Even though other crocodiles have salt glands which would enable them to live in salty water (something which alligators dont have) most other species do not venture out to sea except during extreme conditions.

Is Komodo dragon bigger than crocodile?

Although the Komodo dragon (V. komodoensis) is larger by weight, fully grown crocodile monitors are longer, reach up to 5 meters (about 16 feet) in length from snout to tail.

The list of largest reptiles includes living crocodilians that reach a length of 6 m (20 ft) and more, such as Orinoco crocodile (Crocodylus intermedius), American crocodile (C. acutus), Nile crocodile (C. niloticus), saltwater crocodile (C. porosus), gharial (Gavialis gangeticus) and false gharial (Tomistoma schlegelii). The largest known crocodilian specimen measured 6.78 m (22.2 ft) and was shot in South America by Aim Bonpland.[1][2] Unconfirmed reports of larger crocodilians exist, but examinations of incomplete remains indicate a length of less than 7 m (23 ft) and 2,000 kg (4,400 lb).

The largest Nile crocodile specimen was purported to be a man-eater from Burundi named Gustave ; it was thought to have been more than 6.1 m (20 ft) long. The extinct Crocodylus thorbjarnarsoni was the largest true crocodile to exist, growing up to 7.6 m (25 ft) in length.

Based on its fossils, the latter species was less massive and heavy than the other giant crocodilians, weighing an estimated 3 tonnes. The largest member of the family Alligatoridae is either the Black caiman or American alligator which have been confirmed to grow up to 4.6 m (15 ft) in length and weigh up to 453 kg (999 lb), not as large as the preceding crocodilians but still impressive. The largest member of this family was the caiman-like Purussaurus , from northern South America during the Miocene epoch.

Sarcosuchus imperator of the early Cretaceous was found in the Sahara desert and could measure up to 9 m (30 ft) and weigh an estimated 3.5 tonnes, however it was not a crocodilian. The most massive living member of this highly diverse reptilian order is the green anaconda ( Eunectes murinus ) of the neotropical riverways. [3] [51] The Burmese python , a south-east Asian species is known to weight as much 183 kg and is generally the heaviest snake on average modern wild specimens.

The fossil of the largest snake ever, the extinct boa Titanoboa were found in coal mines in Colombia. The longest venomous snake is the South Asian king cobra ( Ophiophagus hannah ), with lengths (recorded in captivity) of up to 5.7 m (19 ft) and a weight of up to 12.7 kg (28 lb). The second-longest venomous snake in the world is possibly the African Black Mamba (Dendroaspis Polylepis), which can grow up to 4.5 m (14.9 ft).

[3] [54] While not quite as heavy, another member of the viper family is longer still, the South American bushmaster ( Lachesis muta ), with a maximum length of 3.65 m (12.0 ft). [55] The largest of the monitor lizards (and the largest extant lizard in general) is the Komodo dragon ( Varanus komodoensis ), endemic to the island of its name, at a maximum size of 3.13 m (10.3 ft) long and 166 kg (366 lb). [3] Crocodile monitor ( Varanus salvadorii ) is probably the longest living lizard, known to grow as much as 3.23 m (10.6 ft).

It was surpassed in size by the extinct Kawekaweau ( Hoplodactylus delcourti ) of New Zealand, which grew to a length of 23 inches. [59] By far the largest-ever members of this order were the giant mosasaurs (including Hainosaurus , Mosasaurus , and Tylosaurus ), which grew to around 17 m (56 ft) and were projected to weigh up to 20 tonnes. [61] Three species of genus Shastasaurus , including S. sikanniensis , the largest known ichthyosaur The largest of these marine reptiles (extinct for 210 million years) was the species Shastasaurus sikanniensis , at approximately 21 m (69 ft) long and 68 tonnes.

This massive animal, from the Norian stage in what is now British Columbia, is considered the largest marine reptile so far found in the fossil record. [62] However, in 2018, a specimen from Lilstock was discovered to be 25 percent larger, approximately 26 meters in length, [63] with some believing to even dethrone the blue whale in size, making it the largest reptile – let alone marine reptile – to have ever lived, rivaled only by extremely large sauropods such as Maraapunisaurus and Bruhathkayosaurus . [37][67] A much larger tortoise survived until about 2000 years ago, the Australasian Meiolania at about 2.6 m (8.5 ft) long and a weight of over 1 tonne.

[3] The tortoise Colossochelys atlas , of the Pleistocene era from what is now Pakistan and India, was even larger, at nearly 3.1 m (10 ft) and 2 tonnes. [3] The largest seems to be the freshwater turtle Stupendemys , with an estimated total carapace length of more than 3.3 m (11 ft) and weight of up to 1,8142,268 kg (3,9995,000 lb). [68] A close contender is Archelon ischyros , a sea turtle, which reached a length of 4.84 m (15.9 ft) across the flippers and a weight of over 2,200 kg (4,900 lb).

Reptiles have been around some 300 million years, and our planet has seen its fair share of gigantic scaled beasts during its history. That said, only a few behemoths from the golden age of reptiles still exist today.Here we present the five largest reptiles on Earth; the biggest in the four commonly recognized reptilian orders.

Speed capacity and lots of fatty tissue keeps them warm for long sea voyages and deep dives of up to 1,200 meters (4,000 ft). These bad boys hunt in the afternoon, ambushing their prey using their arsenal of powerful sharp claws, a strong tail and a poisonous mouthful of deadly bacteria.

While komodo dragons obviously cant breathe fire, their saliva contains virulent strains of bacteria that grow with uncanny rapidity.

Nile Crocodiles are the worlds second largest extant reptile living in Sub-Saharan Africa regions and an opportunistic apex predator. This species is the largest snake native to South Asia and India, Its attractive pattern, distinctive color and huge size makes it one of the exotic pet.

The largest living reptile

Out of the 10 largest and heaviest reptiles, all except one are crocodiles or related to crocodiles (alligators, caimans or gharials). The odd one out is the leatherback sea turtle, which can weigh almost 1 ton and measures approximately 2 meters in length (6.6 feet).The average saltwater crocodile usually measures between 4.3 and 5.2 m (14 and 17 ft) in length and weighs 400–1,000 kg (880–2,200 lb). It can grow more, but that rarely happens. Even so, there have been reports of a crocodile weighing twice as much as that, making it not only the largest reptile, but also one of the largest predators in the world.The saltwater crocodile,The primary behaviour to distinguish the saltwater crocodile from other crocodiles is its tendency to occupy salt water. Even though other crocodiles have salt glands which would enable them to live in salty water (something which alligators don’t have) most other species do not venture out to sea except during extreme conditions. The saltwater crocodile can travel between areas separated by sea, relying on the relative ease of traveling through water in order to circumvent long distances on the same land mass, such as Australia. They can travel extremely long distances using water currents.A study which tracked the movements of crocodiles via satellite found that one of them traveled 411 km (255 mi) in 20 days. Without having to move around much, sometimes simply by floating, the current-riding behaviour allows for the conservation of energy. They are even known to pause their travels for a few days if the current doesn’t have the desired direction; the crocs simply wait for the current to change direction again and up they go.

Table of heaviest living reptiles[edit]

The following is a list of the heaviest living reptile species, which is dominated by the crocodilians. Unlike the upper weights of mammals, birds or fish, mass in reptiles is frequently poorly documented and many are subject to conjecture and estimation.

Crocodilians[edit]

The largest known specimen among the living crocodilians was an Orinoco crocodile with a length of 6.78 m (22.2 ft).The largest Nile crocodile specimen was purported to be a man-eater from Burundi named Gustave; it was thought to have been more than 6.1 m (20 ft) long. The extinctThe largest member of this family to ever exist was the extinctThe largest member of the family Alligatoridae is either the Black caiman or American alligator which have been confirmed to grow up to 4.6 m (15 ft) in length and weigh up to 453 kg (999 lb), not as large as the preceding crocodilians but still impressive.

Turtles (Testudines)[edit]

The largest living turtle is the leatherback sea turtle (The largest extant freshwater turtle is possibly the North American alligator snapping turtle (The Galápagos tortoise (There are many extinct turtles that vie for the title of the largest ever.

Saltwater Crocodile (Order: Crocodilians)

The saltwater crocodile is the largest living reptile in the world, growing to a length of over 6 meters (20 ft). These mean-toothed giants are able to crush the skulls of cows between their jaws and, should the mood take them, can easily eat a human. The areas of largest croc populations in Australia are clearly marked, so people know where not to stray and so avoid ending up as a croc’s lunch. Saltwater crocodiles range from the tip of Southeast Asia to Australia. As their name implies, they are even known to take to the sea, and have reached locations as remote as the Sea of Japan. Crocodilians belong to an order even more ancient than dinosaurs, so the saltwater crocodile gives us a glimpse into the halcyon days of its gigantic prehistoric ancestors.

Leatherback Sea Turtle (Order: Testudines)

Leatherback sea turtles can measure over 2 meters (7 ft) in length, with a flipper span of almost 3 meters (8 ft), and are unique among turtles thanks to their lack of a hard, bony shell. Instead, their ridged, leathery carapace is built for speed, making them the fastest reptiles on Earth — as well as among the most humungous. Speed capacity and lots of fatty tissue keeps them warm for long sea voyages and deep dives of up to 1,200 meters (4,000 ft).A leatherback’s diet consists mostly of jellyfish — so much so that their populations keep jellyfish numbers in check. Sadly, they often mistake plastic bags for jellyfish, and many have died from ingesting plastic bags. The eggs of leatherbacks are eaten in Malaysia, Thailand and parts of the Caribbean. This has also had a devastating effect on turtle populations. The Leatherback Trust is an organization dedicated to the preservation and survival of these giant yet vulnerable creatures.

Reticulated Python (Order: Squamata)

Did you know that pythons are expert swimmers, and that their sea voyages have distributed them among a variety of islands in the Indo-Australian Archipelago? Yet, as well as being at home in water, reticulated pythons are aggressive constrictors that suffocate their prey and ingest it whole. They have been reliably recorded at 6.95 meters (22.8 ft) — slightly longer than saltwater crocodiles, albeit nowhere near as heavy.

Honorable Mention: Green Anaconda

The world-beating length of the reticulated python has been disputed by claims of even larger green anacondas. Legends and movies about the snake certainly make it seem a fearsome predator. Anacondas have been found to reach 6.6 meters (22 ft), only slightly shorter than the reticulated python. Still, although anacondas chill and thrill us in stories, the reticulated python may be the more fearsome of these two serpentine heavyweights, being on record as having killed and eaten human beings.

Komodo Dragon (Order: Squamata)

Technically, lizards and snakes belong to the same order, but most lizards have legs, while snakes don’t, so we’re representing the four-legged Squamata too! This king of lizards is a deadly hunter reaching lengths up to 3 meters (10 ft). Enter the komodo dragon. These bad boys hunt in the afternoon, ambushing their prey using their arsenal of powerful sharp claws, a strong tail and a poisonous mouthful of deadly bacteria. The term ‘dragon’ certainly seems appropriate when sizing up these ferocious monsters. While komodo dragons obviously can’t breathe fire, their saliva contains virulent strains of bacteria that grow with uncanny rapidity. These bacteria ensure that bites usually result in sepsis and fatal infection. And, like their mythological counterparts, which were immune to their own fire, komodo dragons are immune to their own poisonous secretions. Scientists have yet to discover how this is possible. We’ll leave the field research to them!
