1. The Snout

Animals are considered to have snout when their nose and mouth is projecting together. Both alligator and crocodile possess these snouts. The snout is actually the first sign for you to tell these reptiles apart. Their snouts’ shapes are different and can easily be distinguished.

The snout of a crocodile is V-shaped and more pointed. The snout of an alligator is U-shaped and wide. So, the alligator’s snout is broader while the crocodile’s narrower.

It is important to not that these shapes can also be affected due to their own personal diet. Alligators have wider snouts because they have to break open the shells of turtles. Crocodiles hunt preys like fish, mammals and other reptiles. So, the snout shape is more pointed for easier hunting.

2. Where They Live

As crocodiles are spread around the world, it’s easier to find crocodile. Alligators, on the other hand can only be found in parts of China and the U.S. To be exact, Alligators live in the eastern China and the southeastern U.S.┬áThere are several habitats of crocodiles.

3. Better Living in the Sea

We often find both of these animals living near saltwater. Crocodiles are better than alligators in this matter though. This is because of the special glands they have in the tongues that excrete salt if there is an excessive amount of it.

This makes crocodiles able to spend weeks in the sea. Alligators are usually found in water that is a mixture of fresh and saltwater. This is because their glands don’t work as well as the ones crocodiles have. This is probably why crocodiles are spread more, even across the Caribbean islands.

4. The Toothy Grin

The teeth of crocodiles are always visible, even when their mouths are closed. When closed, the lower fourth tooth are always visible. This makes them looked like they have toothy grin.

Alligators’ teeth, on the other hand, are hidden when their mouths are closed. None of the teeth are visible and this it one of the key to tell them apart. Alligators have wide upper jaw while crocodiles don’t.

The jaw of crocodiles are the in the same size, both upper and lower. Therefore, when these jaws interlock, the teeth are exposed. The snouts are easy to tell apart when they are closed. This difference between alligator and a crocodile makes it easy for you, doesn’t it?

The speed of a crocodile when sprinting can reach 14 kilometer per hour. The maximum speed of an alligator is about 18 kilometer per hour. They are faster in water than on the land.

This is because in water, their tails that are muscular and long help propel the bodies. The speed of crocodile in water can reach 15 kilometer per hour, and 32 kilo per hour for alligators.

They are both great swimmer with the tail helping. On top of that, they are able to hold their breath when submerged in water for up to an hour. Moreover, they also possess great night vision, making them excellent hunters at night.

Except in controlled conditions, feeding them is almost always a bad idea as they will lose some of their fear and see humans as a source of food. They can also mistake small children and pet dogs for prey.

Crocodiles, on the other hand, are much more bad-tempered and far more likely to attack humans, even unprovoked.
Australian saltwater crocodiles are generally considered the most dangerous in the world, followed by Nile crocodiles. American crocodiles, on the other hand, are one of the more timid types that you will find and rarely attack humans. In the US, you are more likely to be attacked by an alligator than a crocodile, although attacks by either are very rare.

On top of this, crocodiles are also more aggressive than alligators, so they are more likely to attack anyone even when unprovoked.

10. Level of dangerous to human

Crocodiles are more dangerous to human. Now, among all the crocodiles out there, the one that human should be careful the most is the Nile crocodile. This is proved by the database from CrocBITE, who keeps track of the attacks worldwide.
