In a new discovery published in the current issue of the science affairs journal Current Biology , new research reveals that unborn baby crocodiles begin communicating to each other and their mothers moments before they are born.
He can talk. He can talk. He can talk….I CAN SINNNNNNNG!!!
It is believed that the noises, described as “umph, umph, umph,” help to syncronize the hatch and signal to the mother that it’s time to start preparing for her brood’s emergence in the big bad world.
Scientists Amelie Vergne and Nicolas Mathevon of the French Universite Jean Monnet discovered the chatter and decided to test its effect. They…
…played a recording of the noise to a group of ready to hatch eggs and played random noises to another. The group subjected to the chatter all hatched within ten minutes of hearing the sound, compared to over five hours for the control group.
Likewise, mother crocodiles who heard the noises immediately began digging up their eggs, even when the eggs were secretly replaced with speakers. Just imagine the surprise on that expectant mom’s face when she realizes that her babies aren’t where she left them! It’s kind of like those videos that they’re always showing on planes of Europeans pulling zany pranks on each other on hidden camera….”Just for Laughs.”
Vergne and Mathevon write in the study, “With crocodile juveniles being highly susceptible to predation, both hatching synchrony and maternal assistance certainly increase the fitness of newborns.” That statement’s a lot funnier if you say it with a really thick French accent.
