Young crocodiles have known to call their mothers before they were born

Research by French biologists helped to better understand the reproduction of crocodiles. They found that young crocodiles knew to call their mothers before they got out of the eggs.

The experiment was carried out at the Pierrelatte (Drôme) crocodile farm that allowed 10 crocodiles to be spawned from three months ago. The eggs were placed in the incubator.

The team recorded the cries before the eggs hatched in the incubator, then buried in a sand speaker to emit two series of sounds that were the sounds of young crocodiles and meaningless noises.

Of the 10 female crocodiles tested near the machine, 8 reacted immediately with cries before the eggs hatched and dug sand during recording without paying attention to other sounds. The ninth child does not react with the above two signals, while the 10th one digs sand in both cases.

Dr. Amélie Verge of Jean Monnet University in Saint-Etienne explained that the cries of young crocodiles in eggs make the mother crocodile react immediately because this is a real information that eggs are about to hatch.
