Smart Crocodiles
By ...

You’ve heard of homing pigeons and perhaps about household pets finding their way to their owners hundreds of miles away, right? Now researchers with the University of Queensland in Australia have discovered that saltwater crocodiles have similar instincts.

Apparently, animal control specialists have been moving the reptiles from populated areas to more isolated spots. And the croc experts have learned that some of the relocated reptiles have traveled up to 250 miles to get back home. Satellite transmitters tracked them as they swam toward their original habitats using cues that the scientists have yet to determine.
