These animals come in varying sizes and are found in almost all places in the world where the climate allows them to exist.
Their intelligence and problem solving ability is great. A variety called the Siamese Crocodile even has the mother and father taking care of the offspring.
However, it appears that crocodiles can never be truly reliable pets.
One very interesting thing about crocodiles is that when crocodiles born and bred in captivity are left in their natural habitat, they do not need to adapt at all. Its like a duck taking to water.
Now, is this because crocodiles are more evolved than other species? Or because they are less evolved? Food for thought.
Take that, lions and other evolved animals.
