18 Types Of Crocodiles Found Across The World
American Alligator (Alligator mississippiensis)
The American alligator (Alligator mississippiensis) is a large, semi-aquatic, armored reptile native to the Southeastern United States. Here are some key characteristics and facts about the American alligator:
– Size: The body of an American alligator ranges from 6 to 14 feet long. Male alligators are larger than females, with an average size of 11.2 feet (3.4 meters) for males and 8.2 feet (2.6 meters) for females. Exceptionally large males can reach a weight of nearly half a ton or 1,000 pounds (454 kilograms).
– Appearance: American alligators have a nearly black color, prominent eyes, and nostrils with coarse scales covering their entire body. They have a large, long head with visible upper teeth along the edge of their jaws. Their front feet have five toes, while their rear feet have four toes that are webbed.
– Habitat: American alligators are found in freshwater, slow-moving rivers, swamps, marshes, and lakes. They can tolerate brackish water for brief periods but are primarily freshwater species.
– Diet: Alligators are opportunistic feeders, and their diet includes fish, turtles, wading birds, snakes, frogs, small mammals, and even smaller alligators they find near the shoreline of their habitat. Young alligators feed on small fish and aquatic invertebrates.
– Behavior: American alligators are active year-round, but they are most active in the warmer months. They are known for their social displays, which include bellowing, grunting, and hissing. Alligators are also agile swimmers and can often be seen floating or swimming with only their eyes and nostrils exposed.
– Conservation: The American alligator was once on the verge of extinction but has made a remarkable recovery due to strict conservation measures and extensive research. It is no longer endangered, except in scattered areas of its range, but is still listed as threatened by the federal government due to its similarity in appearance to the American crocodile.
American Crocodile (Crocodylus acutus)
The American crocodile (Crocodylus acutus) is a large, semi-aquatic reptile that can be found in coastal areas throughout the Caribbean, as well as at the northern end of its range in south Florida. Here are some key facts about the American crocodile:
– The American crocodile has a large, lizard-like body with four short legs and a long, muscular tail.
– Their hides are rough and scaled, and their body color can range from tan gray to olive gray, with darker patches.
– Unlike other species of crocodile, American crocodiles are not green.
– They have a narrow, tapered snout, and their fourth tooth on the lower jaw is exposed when the mouth is closed.
– American crocodiles live in brackish or saltwater areas, such as ponds, coves, and creeks in mangrove swamps.
– They can also be occasionally found inland in freshwater areas of the southeastern Florida coast due to the extensive canal system.
– American crocodiles are apex predators, and their diet mainly consists of small mammals, fish, frogs, birds, and turtles.
– Hatchlings forage on land, feeding mainly upon insects, while young crocodiles tend to consume aquatic invertebrates and small species of fish.
– The American crocodile is classified as a Vulnerable species on the IUCN Red List.
– The species is exposed to illegal hunting and poaching due to its hide, as well as habitat loss from human development, pollution, and commercial farming.
– The overall number of their population is unknown, but it is currently increasing.

– Scientific Name: Crocodylus niloticus
– Common Names: Nile crocodile, African crocodile, Ethiopian crocodile, common crocodile
– Size: The average length of a Nile crocodile is between 4 to 4.5 meters (13.1 to 14.7 feet), with a weight of around 410 kg (900 lb). However, exceptionally large specimens can reach up to 5 meters (16.4 feet) in length and weigh 600 kg (1,300 lb).
– Habitat: Nile crocodiles are found in various types of aquatic environments, including lakes, rivers, swamps, and marshlands. They are widespread throughout sub-Saharan Africa, the Nile Basin, and Madagascar.
– Diet: The main diet of Nile crocodiles consists of fish, but they are opportunistic predators and will attack almost anything that crosses their path, including zebras, small hippos, porcupines, birds, and other crocodiles. They can also scavenge carrion and can eat up to half their body weight in a single feeding.
– Reproduction: Nile crocodiles exhibit parental care, which is unusual for reptiles. Females lay their eggs in nests, which can be either holes in the ground or mounds of plant material and soil. The eggs are then incubated, and the female may help the hatchlings to the water once they emerge.
– Conservation Status: The Nile crocodile is currently listed as least concern on the IUCN Red List, which means it is not considered to be at significant risk of extinction. However, the population trend is unknown.
The Nile crocodile is known for its aggressive nature and has a reputation as a man-eater. Its proximity to human settlements and its indiscriminate diet contribute to frequent encounters with humans, resulting in attacks and fatalities.

Chinese Alligator (Alligator sinensis)
The Chinese alligator (Alligator sinensis), also known as the Yangtze alligator, China alligator, or historically the muddy dragon, is a crocodilian endemic to China. It is one of the two living species in the genus Alligator, the other being the American alligator (A. mississippiensis). Here are some key characteristics and facts about the Chinese alligator:
– Size: Adult males grow to about 2 meters (6.5 feet) in length and can weigh up to 40 kg (88 lb). The largest Chinese alligator measured in recent times was 7 feet and 1 inch, about half the size of the largest living American alligators.
– Appearance: Chinese alligators are yellowish-gray in color with pronounced black spotting on the lower jaw. They have four short claw-tipped limbs with five partially webbed toes on each limb. Their long, thick tail provides the primary locomotive force in the water. They have osteoderms, dermal bone lying over the epidermis used as armor, covering both the back and underside of the body. The Chinese alligator has a slightly upturned snout and a bony plate in the upper eyelid, which is missing in the American alligator.
– Habitat: Chinese alligators are mostly found in slow-moving bodies of water such as streams, rivers, and swamps in the lower Yangtze region, primarily in the Anhui and Zhejiang provinces in eastern China. They inhabit marshlands, ponds, lakes, reservoirs, river backwater canals, rice paddies, and irrigation networks.
– Behavior: Chinese alligators are mostly nocturnal and spend a large part of the year in complex networks of underground burrows containing above and below-ground pools of water. These burrows are some of the most extensive within the crocodilian world, extending for up to 25 meters, with various side channels that accommodate multiple animals within the same burrow.
– Conservation: The Chinese alligator is critically endangered, with a population estimated to be between 92 and 114 individuals. Habitat loss and population declines have led to its restricted distribution in the Anhui Province of China. Conservation efforts, including monitoring programs and large-scale captive breeding endeavors, are underway to protect and restore the species. Successful reintroductions of captive-bred individuals have been observed, indicating the species’ potential to adapt to restored habitat.
Australian Freshwater Crocodile (Crocodylus johnsoni)

– Appearance: The freshwater crocodile has a slender snout and a light brown body with darker bands on its body and tail, as well as lighter brown bands on its snout. The nostrils and eyes sit at the top of the head, and the fine sharp teeth are clearly visible even when the mouth is closed.
– Habitat: This species occupies various freshwater areas such as lagoons, rivers, billabongs, and swamps. They show a strong fidelity to their dry season water body, often returning to the same water body in two successive dry seasons. Freshwater crocodiles may also shelter in burrows among the roots of trees fringing the water bodies they inhabit.
– Distribution: The Australian freshwater crocodile is found in the Northern Territory of Australia, Queensland, and northern and western Australia. They occur along all but the near coastal reaches of the rivers, streams, and creeks that flow into the waters off northern Australia between King Sound in the southwestern Kimberley, Western Australia, and the northern part of Cape York Peninsula, Queensland.
– Behavior: Freshwater crocodiles can perform a “high walk” to move overland, holding their bodies high so that the belly and most of the tail do not touch the ground. Track marks indicate that these crocodiles may walk considerable distances at the end of the wet season in search of a dry.
False Gharial (Tomistoma schlegelii)
The False Gharial (Tomistoma schlegelii), also known as the Malayan Gharial, Sunda Gharial, and Tomistoma, is a freshwater crocodilian of the family Gavialidae.
It is native to Peninsular Malaysia, Borneo, Sumatra, and Java. The species is listed as Vulnerable on the IUCN Red List, with a global population estimated at around 2,500 to 10,000 mature individuals.
The False Gharial is characterized by its long, narrow snout, which is filled with 76-84 sharp, pointed teeth. It has a streamlined body, a muscular tail, eyes and nostrils on top of the head, and a palatal valve that prevents water from entering the throat while underwater. The species can grow to 4-5 meters in length, and possibly even larger.
Population surveys have shown that the distribution of False Gharials is more spotty than it used to be, putting the animals at risk of genetic isolation. The largest known populations are in Sumatra and Kalimantan, with smaller established populations in Malaysia.
The species is almost entirely found today in peat swamps and lowland swamp forests.
