Crocodile is one of the most impressive and deadly predators in the world. They are experts at camouflage, patiently waiting for unsuspecting prey to approach before charging at high speed. They have thick, stiff skin and dozens of sharp teeth in their jaws that produce the greatest bite force of any living animal. Apart from humans, adult crocodiles have no natural predators.
