Baby crocodiles talk to each other in their eggs

Baby crocodiles "talk" to their mothers and their unborn siblings even before they hatch, perhaps indicating that they are ready to leave the egg, according to new research.

French scientists Amelie Vergne and Nicolas Mathevon of Universite Jean Monnet in Saint-Etienne noticed that the young reptiles make a noise, described as sounding like "umph, umph", in the moments immediately before they hatch.
