Different of Alligator Vs. Crocodile

Despite the enormous differences between crocodiles and birds, are considered species are closely related. Often confused with alligators crocodiles are mainly due to their similarities in appearance. But these ferocious man-eaters are classified in different families. Let's look at various aspects of alligator vs crocodile.

Crocodiles are very similar to alligator, if the habit of the appearance, habitat and diet. Therefore, it is very difficult to tell an alligator from a crocodile. But when studying the basic characteristics of each group separately, it is easy to get to know the difference between alligators and crocodiles. Comparison of alligators and crocodiles are summarized below:

Taxonomic family
First, we compare the alligators and crocodiles in terms of their taxonomic families. Although these two reptiles belong to the same order of crocodiles, alligators are classified in the family Alligatoridae, while crocodiles are members of the family Crocodylidae.

As for the comparison between habitats of alligators and crocodiles, the two spend their lives in and around streams and lay their eggs on land. But the difference is alligators prefer fresh water habitat, while alligators prefer to live in brackish or seawater.

Another difference is the behavior of alligators and crocodiles and temperament. Both reptiles are furious, but when you look, you will notice that crocodiles are more aggressive than alligators. The crocodiles are trying to escape most of the time when approached by humans, while crocodiles tend to attack everything that passes through the area.

Body color
The body color is darker than the alligators and crocodiles. Crocodiles are mostly black or gray color, while the color is olive green or brown crocodile.

Muzzle shape
The most notable difference between an alligator and a crocodile is the shape of the muzzle. Alligators have broader snouts in a "U", while the shape of the crocodile's mouth is narrow and form a V in the final.

Placement of the jaw
The position of the teeth is also a distinctive feature to delineate the alligators and crocodiles. Positioning of the jaw of a crocodile is such that the upper jaw is wider and covers the lower jaw. In the case of a crocodile, the width of the upper and lower jaw are the same, therefore, the teeth of the lower jaw is through the mouth is closed.

The rear
In crocodiles, no irregular bursts evident in the hind legs, while the margins are present in the hind legs and feet of crocodiles.

The skin pressure receptors (DPRS)
CMA are small, black, sensory pits that help detect changes in water pressure. In both crocodiles and alligators, CMA serve an important organ for locating prey. In crocodiles, CMAS are only present around the jaw, while in the crocodiles, these sense organs are present in almost all scales of the body.

Salt gland
Both alligators and crocodiles have structurally altered the salivary glands (salt glands) in the language. Crocodiles use these salt glands to remove excess salt from the body, while in the crocodiles, these salt glands are not functional. This is the reason that a crocodile can not tolerate salt water, while crocodiles can not.

With this brief information about a crocodile crocodile vs one, I hope you understand the differences between the two reptiles. So next time you visit a zoo, trying to identify the crocodiles and alligators, and note the subtle differences.
