The Clickable Croc

Launch interactive Anatomy of a Croc


Crocodiles inspire fear, which may have something to do with their coolly dominating presence. After all, for nearly 100 million years during the Mesozoic era (248-65 million years ago), the crocodilian order ruled the Earth. Today's crocodiles have changed remarkably little since then. They are still the most advanced reptile species, and they still terrify most people. In this feature, we ask that you put aside your fears and get up close and personal with a Nile crocodile.
