Biggest Reptile in the World?

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).

When most people think of huge reptiles, their minds immediately jump to dinosaursbut youre highly unlikely to come across one of those on your next hiking trip! What are some of the largest reptiles that still roam the Earth and can be encountered today? This list arranges these massive reptiles in order by their mass, though other dimensions such as length can reach impressive numbers as well.

This large reptile can live to be over 100 years old if left aloneunfortunately, however, habitat destruction and poaching have threatened the tortoises numbers. The shell of the Galpagos Tortoise may look astoundingly heavy, even for such a large reptile to carry around.

Healthy Green Sea Turtles enjoy long life spans of up to 80-100 years. Average Weight: 441 pounds Average Length: 3.2 feet Diet: Primarily Carnivorous Location: Subtropical and tropical regions of the Atlantic, Pacific, and Indian Oceans The beautiful Loggerhead Sea Turtle is a wide-ranging species , and can be found in subtropical and tropical waters all around the globe.

These turtles migrate vast distances between feeding grounds and nesting beaches, traveling hundreds of miles out to sea. Female Loggerhead Sea Turtles return to the beaches where they hatched to lay their own eggs, sometimes crossing thousands of miles of ocean to get there. Adult Loggerheads primarily feed on mollusks and crustaceans, easily crushing the hard exoskeletons with their powerful jaws and sharp beaks.

Jellyfish, sargassum algae, and other soft foods are sometimes also included in the turtles diet. The Loggerhead Sea Turtle gets its name from the way its sturdy, oversized head vaguely resembles a log. While almost completely uninterested in humans, these giant reptiles have been known to spend time in groups of their own species.

They are most active early in the morning, preferring to eat and socialize before it gets too hot. The Malayan Gharial is a freshwater reptile, and is native to six river systems in Sumatra and Malaysia. Fossils of this species have been found in southern China, indicating that it used to inhabit a much broader area than it does today.

Their unique snouts contain sensory cells that help them pick up vibrations of other life in the water. Once prey comes within range, Gharials whip their heads to the side and snatch it out of the water. It often lies still on the shore, basking in the sun, and will usually scramble into the water to avoid confrontation if startled.

The impressive Black Caiman owes its name to its strikingly dark exterior, which helps it camouflage itself during nocturnal hunting sessions and more effectively warm itself in the sun. The Black Caiman is considered an apex predator, and can take down and eat just about any animal that crosses its path. It possesses enough force behind its bite to puncture turtle shells, and boasts enough strength to drown large prey animals underwater.

While most turtles have a hard, rigid shell covering their backs and stomachs, this hulking species instead has a leathery exterior with ridges that help streamline it while swimming and diving to extreme depths. Leatherback Sea Turtles also utilize adaptations such as their size and a layer of insulating fat to expand their habitat range to colder waters than most reptiles can tolerate . This impressive sea turtle uses its delicate mouth to survive off a diet of jellyfish and other soft-bodied creatures.

The Leatherbacks throat is lined with small, downward-curving spines known as papillae, which make it easier to swallow its prey. This critically endangered crocodiles habitat is almost entirely restricted to the Orinoco Basin in Colombia and Venezuela. The Orinoco Crocodile is the largest predator in South America by mass , as well as the rarest, and comes in an interesting set of colors.

These crocodiles are often pale green or yellow in color, and sport a smattering of dark spots that help with camouflage. Orinoco Crocodiles retain the unique ability to shift their color over time, as the melanin levels in their skin change with age. This giant reptile is considered to the the largest freshwater predator in Africa, as well as the most common.

A strange myth once claimed that these crocodiles need to allow their prey to begin decomposing before they can tear away the meat and eat their meal. This massive hunters diet usually consists of fish, but it has nothing against eating birds, small hippos, and other crocodiles . This stealthy hunter lies in wait for prey animals to come to the edge of the water for a drink, and then strikes with its powerful jaws, dragging the creature underwater until it drowns.

However, Saltwater Crocodiles have a menacing reputation for being unusually aggressive towards people . Female Saltwater Crocodiles lay clutches of around 50 eggs, and watch over them carefully until they hatch.

Wild World is home to largest collection of rare reptilians such as longest saltwater crocodile,biggest Reticulated Python,heaviest Green Anaconda and heaviest venomous snake Diamondback Rattlesnake. Giant reptiles of World also includes Chinese Ratsnake,Iguana, pit viper snake,New Caledonian Giant Gecko,Nile monitor and Australian Monitor.

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.

Most reptiles are measured from snout to vent (that is, the tip of the nose to the cloaca). However, measurements of total length are common for larger species, and shell length is used to gauge the size of turtles. The body size of living reptiles varies widely. Dwarf geckos (Sphaerodactylus parthenopion) are the smallest reptiles and have a snout-to-vent length of 1618 mm (0.60.7 inch). In contrast, giant turtles, such as the leatherback sea turtles (Dermochelys coriacea), possess shell lengths of nearly 2 metres (about 7 feet). In terms of total length, the largest living reptiles are the reticulated pythons (Python reticulatus) and saltwater crocodiles (Crocodylus porosus), which may grow to more than 7 metres (23 feet) as adults. Some ancient reptile groups had members that were the largest animals ever to live on the landsome sauropod dinosaur fossils measure 2030 metres (6698 feet) in total length. The largest marine reptiles, the pliosaurs, grew to 15 metres (50 feet) long.

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.


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.

Size range

Most reptiles are measured from snout to vent (that is, the tip of the nose to the cloaca). However, measurements of total length are common for larger species, and shell length is used to gauge the size of turtles. The body size of living reptiles varies widely. Dwarf geckos (The reptile groups also show a diversity of morphologies. Some groups, such as most lizards and all crocodiles, possess strongly developed limbs, whereas other groups, such as the worm lizards and snakes, are limbless. Reptilian body flexibility ranges from the highly flexible forms found in snakes to the inflexible armoured bodies of turtles. In addition, the tails of most turtles tend to be short, especially when compared with the long heavy tails of crocodiles.Giants in any animal group always attract attention and are often exaggerated. Anacondas (At about 5.5 metres (18 feet), the king cobra (Five species of crocodiles may grow larger than 6 metres (20 feet). Nile crocodiles (The giant among living turtles is the marine leatherback sea turtle (The largest modern lizard, the Komodo dragon (Within each reptile group, with the possible exception of snakes, no living member is as large as its largest extinct representative. At about 2.7 metres (9 feet) in total length, the leatherback sea turtle is smaller thanThe smallest living reptile is the adult male nano-chameleon (
