American crocodile

The American crocodile has lived on Earth for millions of years, but today their numbers are rapidly declining because they are hunted for their skins. These cold-blooded carnivorous reptiles have long pointy snouts full of sharp teeth. American crocodiles use their long tails and webbed feet to help them quickly swim through salty coastal waters.
