What is the difference between alligators and crocodiles?
- 1 decade agoFavorite Answer
- Crocodiles are from the crocodylidae family.
- Crocodiles has a very long, narrow, V-shaped snout. Because the narrow crocodile snout, although still very powerful, is not really suited for prey like turtles but is very versatile for fish and mammals.
- The crocodile's upper and lower jaws are nearly the same width, so the teeth are exposed all along the jaw line in an interlocking pattern, even when the mouth is closed. They also have an enormous 4th tooth on the lower jaw that is accommodated by depressions in the upper jaw just behind the nostrils.
- Crocodiles like brackish water and sometimes even ocean.
- Crocodiles have a lighter olive brown coloration.
- The glands on their tongues, crocodiles still use these glands to excrete excess salt.
- Crocodiles lay their eggs in mud or sand nests near brackish water.
- In the United States crocodiles are only found around the southern tip of Florida, though they can also be found in the Caribbean, Central America and South America.
- Alligators and caiman are from the alligatoridae family.
- The alligator's snout is wider and U-shaped. Because of the wide snout of the alligator it packs more crushing power to eat prey like turtles that constitute part of its diet.
- The Alligator as a wider upper jaw, so when its mouth is closed the teeth in the lower jaw fit into sockets of the upper jaw, hidden from view. Only the teeth of the upper jaw are exposed along the lower jaw line. Even the enormous 4th tooth on the bottom jaw, which is exposed in a crocodile, is hidden in the alligator.
- Alligators prefer freshwater.
- Alligators have blackish coloration.
- Alligators seem to have lost this ability to excrete excess salt
- Alligators make their nests out of mounds of vegetation surrounding freshwater to lay their eggs.
- Alligators are found in the southeastern United States, and South Florida is the only known place in the world where crocodiles and alligators cohabitate the same areas.

Crocodiles are a member of the Crocodillia Order so are alligators. However Alligators are Alligatoridae Family where as the Crocodiles are a member of the Crocodylidae family.
There are two living alligator species: the American alligator (Alligator mississippiensis) and the Chinese alligator (Alligator sinensis).American alligators live in freshwater environments, such as ponds, marshes, wetlands, rivers, lakes, and swamps, as well as brackish environments. Southern Florida is the only place where both alligators and crocodiles live side by side.
Crocs can be found around the world in freshwater, brackish water and even pure saltwater.
The most obvious external differences are visible in the head—alligators have wider and shorter heads, and a more U-shaped than V-shaped snout. The alligator's upper jaw is wider than its lower jaw, and the teeth in the lower jaw fit into small depressions in the upper jaw. The upper and lower jaws of the crocodiles and caimans are the same width, and teeth in the lower jaw fall along the edge or outside the upper jaw when the mouth is closed. When the crocodile's mouth is closed, the large fourth tooth in the lower jaw fits into a constriction in the upper jaw. For indistinguishable specimens, the protruding tooth is the most reliable feature to define a species.
Alligators lack the jagged fringe which appears on the hind legs and feet of the crocodile and have the toes of the hind feet webbed, not more than halfway to the tips. Alligators strongly prefer freshwater, while crocodiles can better tolerate seawater due to specialized glands for filtering out salt. However, both taxa can survive in either.
Both species of alligator also tend to be darker in color than crocodiles—often nearly black (but color is very dependent on water quality). Algae-laden waters produce greener skin, while tannic acid from overhanging trees can produce often darker skin.
When cleaning alligator pools, some zookeepers can tread on alligators without eliciting a response, though crocodiles almost invariably react aggressively and are for the most part more aggressive in their natural habitat.Source(s): WIKI what a wonderful tool

They are both in the crocodilian family, but an alligators snout is wider, and a crocodiles snout is a more slim V-shape. If you can see teeth when the animals' mouth is closed then its most-likely an alligator. Their diets are different. Alligators prefer freshwater, while crocs like brackish water, and sometimes ocean. Crocs are usually a light brown color, while alligators are an almost black color.Source(s): Internet and watching Animal Planet

selection - crocs, africa, asia, australia Gators, Americas Crocs - extra exterior tooth variations interior the morphology of the cranium, specially to do with even if if or no longer they have a million nasal hollow area or 2, won't be able to bear in innovations which way around they're nonetheless.
