Let me tell you a few things about my favorite animal, the Crocodile. First off they're are 23 species of crocodile, only 3 of them are alligators- the American alligator, the Chinese alligator, and the kamen, that's it ^_^

Alligators can only go into fresh water, rivers, lakes, swamps and such. Crocodiles can go into any water, yes there are saltwater crocodiles that are in the ocean. Other differences to tell them apart is the teeth, if the teeth are visible when their mouth is closed it is a crocodile, if not it's an alligator.

The biggest crocodiles are the saltwater and Nile(Nile river) crocodile, they can grow up to 20 feet. Crocodiles are the only reptiles to have 6 arteries like mammals, this makes them have the ability to draw adrenaline into their bodies, they also have the ability to adapt to changing conditions. There is a reason they have been around for the past 100,000 years after all ^_^

Their ability to draw adrenaline gives them the ability to burst of of the water lock their vice grip like jaws around they preys neck and drag them into the water for their patented death roll, which is were they roll in the water over and over until the prey drowns to death or the body part they have detaches.

Their ability to adapt is amazing, there is one recorded entry of they're ability to adapt, a crocodile sat at a campsite for 3 days watching 3 campers, the third day when the campers went to bed, the crocodile snuck into their tent and killed one of the campers and bit another before the 3rd camper finally killed it with a shotgun they brought. Like I said, there is a reason they lived so long.
