Native to China and southern North America, alligators are freshwater crocodilians. Additionally, because there are only two species, they are relatively rare.
The Chinese alligator is actually so rare in the wild that zoos are home to more surviving varieties.
That’s a different story in the US. Even though there are over 5 million North American alligators in the wild, they are categorized as “of Least Concern.”
Alligators are large, flat, and have elongated mouths, just like crocodiles. The majority are also opportunistic hunters, sleeping in marshes and consuming fish, birds, and aquatic animals.
Additionally, they have a thick layer of brown or green hide that protects them from predators, just like other crocodilian (crocodile-shaped) animals.
They share non-overlapping scales, or “scutes,” with all other crocodilians. Regular rows and patterns are used to arrange these. Similar to alligators may develop them like fingernails since they are also composed of keratin.
Alligators aren’t special, though. In reality, there are seven different types of crocodilians.
1. Crocodiles
Scientific name (genus): Crocodylus
Summary: Despite preferring saltier water than their cousin, crocodiles and alligators are nearly identical save for the structure of their noses.
The most diverse group of crocodilians are crocodiles, also known as “True Crocodiles.” The Americas, Asia, Australia, and India are home to 13–14 species of true crocodiles, which can be found all around the world.
However, only Florida is home to actual alligators and crocodiles. Because crocodiles prefer brackish water, which is acidic and salty fresh water, or saltwater, the two animals avoid each other elsewhere.
The distinctions don’t end there. Crocodiles, for instance, are often larger. However, that truly varies per species.
The American Crocodile is an example of a crocodile, which typically weighs between 800 and 1000 pounds, whereas a male alligator weighs about 700 pounds.
Additionally, crocodiles don’t have the distinctive black spots that similar to alligators do. But not every alligator has those spots.
Other than that, these creatures have a remarkably similar appearance and sound. In actuality, they have nearly the same physiological composition and appearance, and they consume extremely similar meals.
2. Dwarf Crocodiles
Scientific name (genus): Osteolaemus
Summary: Although they are typically one-tenth of the size of real crocodiles, dwarf crocodiles have the exact same appearance.
The small genus of crocodilians known as dwarf crocodiles is closely linked to the real crocodile. In comparison to real crocodiles, they are also little, as the name implies.
Both of the genus’s extant species grow to a maximum length of roughly six feet. Males hardly ever reach 180 pounds, while females hardly ever reach 80 pounds.
That’s a significant contrast to the real crocodile, of which the greatest specimens have been measured at 23 feet and weighing more than 2,200 pounds. Naturally, the “average” size of a real or dwarf crocodile is far less.
Additionally, both kinds of dwarf crocodiles are indigenous to Africa. Only in the Congo, though, is one.
The dwarf crocodile is not substantially different from other crocodilians except in appearance. But we don’t know why, some populations have been known to develop red and orange pigment when they live in caves.

3. Caimans
Scientific name (subfamily): Caimaninae
Summary: With the exception of size, it may be difficult to distinguish between caimans and alligators, which are the closest living relatives of each other.
The Alligatoridae family includes the little crocodilians known as caimans. From the broad-snouted to the diminutive, there are currently nine species of caimans in the world.
A unique characteristic of the Alligatoridae family is that caimans are the only other animal. Nonetheless, many of them are genetically closer to crocodiles due to the considerable genetic separation between them and similar to alligators.
Some, like the broad-snouted caiman, are hard to distinguish from small alligators, though. Similar to alligators, caimans are heavier but also shorter.
For instance, the majority of caimans are hardly longer than ten feet in length. The majority also weigh between 13 and 88 pounds on average.
The black caiman, meanwhile, can grow to be more than 16 feet tall and weigh more than 2,000 pounds. Black caimans are typically around a quarter of that size.
Cuver’s dwarf caiman is often shorter than five feet. It also often weights around 15 pounds. It is the tiniest crocodillian as a result.
Additionally, all caiman species are native to South America, with the region of the Amazon living a large number of them. They typically live in vast, slowly flowing rivers and, similar to alligators, like fresh water.
4. Gharial
Scientific name: Gavialus gangeticus
Summary: At first glance, gharials look like alligators, but upon closer inspection, their snouts are noticeably longer and thinner than those of their cousins.
The Indian subcontinent is home to gharials, also referred to as “fish-eating crocodiles.”
Gharials resemble alligators in appearance. But because of their long, thin snouts, gharials cannot bite with the same force as an alligator or crocodile.
Because of their inability to chew and bite off food, they are largely limited to eating fish. Given that the gharial is nearly exclusively aquatic, that fits it perfectly.
Unlike most other crocodilians, the majority spend their entire life in the water and do not hunt carrion or small mammals.
In addition, gharials are among the longest crocodilians in terms of weight. For example, it has been reported that males can reach a length of over 30 feet and weigh over 2,000 pounds. The majority of gharials are much smaller, with an average length of 8 to 15 feet.
5. False Gharial
Scientific name: Tomistoma sclegelii
Summary: False gharials similar to alligators less than many other species on this list due to their reddish mottling and short snout, However, it would still be challenging to distinguish them from one another from a distance.
The crocodile known as the fake gharial is very similar to alligators.
Its snout is longer than an alligator’s, but it is shorter than that of the real gharial. However, only the genuine gharial can match its snout, which is still among the slimmest of any crocodile.
Moreover, the majority are really little. Most of them weighed hardly more than 450 pounds, and the longest guy ever measured was only 15 feet. H.
They are, however, some of the most vivid crocodilians, with reddish brown and black or white mottling patterns.
The fake gharials are all native to Malaysia, Sarawak, and Indonesia. Although they are not indigenous, there are other populations in Thailand, Vietnam, and Singapore. Furthermore, counterfeit gharials are extremely varied and can be found in rivers and marshes.
The fact that false gharials attack and consume nearly anything they can sets them apart from true gharials. As a result, they eat a variety of foods, including deer, fish, insects, and monkeys.

6. Slender-Snouted Crocodiles
Scientific name (genus): Mecistops
Summary: Alligators and slim-snouted crocodiles share a similar appearance, although the latter have more mottling on the shoulders and back and an elongated, V-shaped snout.
Two medium-sized species of crocodiles that are indigenous to sub-Saharan Africa are known as slim-snouted crocodiles. Since the genus is genetically distinct, it was removed from the list of real crocodiles.
Adults of both species of slender-snouted crocodiles typically weigh 350 pounds and measure around four feet. On the other hand, older specimens can weigh more than 700 pounds and reach lengths of 14 feet.
They are also distinguished by a slender, long, tapering snout that forms a “V,” as the name implies.
With more than 100 days required for egg hatching, slim-snouted crocodiles also have one of the longest egg incubation times of any crocodilians. Additionally, the sex of the eggs is determined by the temperature during the first three weeks of incubation.
Conclusion
One of the oldest animal species still in existence is the crocodile. As a result, their abundance is not surprising. The fossil of Deinosuchus, a huge crocodile that was likely 30 to 40 feet long, dates back 82 million years.
Typically, modern crocodilians are shorter. Still, a lot of them retain their original appearance from millions of years ago.
Frequently Ask Question(FAQs):
How can something resemble an alligator?
True crocodiles, alligators, caimans, gharials, and false gharials are all members of the order Crocodilia, which is mostly composed of big, semiaquatic, carnivorous reptiles. The word “crocodile,” or simply “crocodilian,” describes a member of this order.
What creature resembles an alligator?
Crocodilians. This family of reptiles includes gharials, caimans, crocodiles, and alligators. Large creatures with strong jaws, long, heavy tails, small legs, and thick, plated skin are known as crocodilians.
What animal is similar to alligators?
Alligators share similarities with gharials, caimans, and crocodiles. They can be identified by their nose shapes, but as they are all extremely hazardous, it is best to avoid them all.
Which fish similar to alligators?
Alligator gar
Most people may remember their first encounter with an alligator gar. They have a remarkable appearance in the world of fish. When alligator gar grow to enormous size, they resemble something that belongs swimming with dinosaurs rather than fish and crappie. However, their distinctiveness extends beyond their appearance.
