Feeding mechanism

Orange nectar bats in Costa Rica were observed utilising a unique feeding mechanism that has not been seen in any other animal, this mechanism allows it to pull liquid against gravity using a pumping mechanism. The orange nectar bat's tongue contains two grooves filled with tiny muscles that force the nectar up into the bat's mouth. Two forces are at work here, capillary action and muscle force. The orange nectar bat likely developed this method independently of other species due to its unique mouth physiology.[2]
