Crocs are like horseshoe crabs and other organisms that are extremely efficient and "[crocs] are an ancient lineage, and are believed to have changed little since the time of the dinosaurs. They are believed to be 200 million years old whereas dinosaurs became extinct 65 million years ago; crocodiles survived great extinction events" from wikipedia...
I'd think we should be spending an awful lot of time studying the croc imho.
