    • Alligators and crocodiles are essentially the same thing. While the term alligator and crocodile are occasionally (and erroneously) used simultaneously by the general population, they aren’t the same thing.
    • Alligators are predatory toward humans. Compared to saltwater crocodiles in Australia or Nile crocodiles in Africa, alligators in the U.S. aren’t nearly as dangerous to humans.
    • If you are being chased by an alligator on land, run in a zig-zag pattern. While alligators are certainly better swimmers than humans (they can move about 2-4 times faster than us in the water), they’re not quite so nimble on land.
    • Alligators can’t climb. Alligators are not only adept climbers but they are also capable of jumping out of the water. Young alligators are typically the most active climbers, as they tend to scramble onto low branches near the water to get some sun, but females also climb up steep and sandy banks to find a good place to build a nest and lay their eggs.

    Alligators have broad snouts, unlike crocodiles, which have relatively narrow jaws. Inside their mouths are two rows of teeth–one on the top and one on the bottom–that run all the way around their mouth like the letter ‘U’. Most of their 74-80 teeth are roughly the same size; with the exception of the fourth tooth from the front. This tooth, which ...

    Alligator teeth are not sharp, they’re actually fairly blunt and dull. They don’t use their teeth to rend chunks of flesh from large prey, and because of their massive jaw muscles, they’re unable to chew. Instead, alligators use their numerous teeth to clamp down on slippery prey like fish and birds. Once an alligator has something in its mouth, th...

    Alligators frequently lose or break teeth. These are almost immediately replaced by the growth of new teeth from the surrounding dental laminae. An alligator may grow hundreds of teeth in its lifetime, and it’s all thanks to a very special kind of cell located in the dental lamina. Alligators regenerate teeth as quickly as humans regrow fingernails...

    Because alligators and humans frequently share the same habitat, contact between the two is common. Small alligators would rather hide, or swim away, than confront a human, and will only bite if cornered or threatened. Large alligators however are big enough, and deadly enough, to attack and even kill humans, though instances of this are rare. If y...
