Which of these animals has only one ear?
Mole
Lemur
Praying mantis

Fact: Until relatively recently, scientists believed that praying mantises were unable to hear as no external could be found on their bodies. However, it turned out that scientists were looking in the wrong place! The praying mantis actually has one single ear and it is located right in the middle of its chest. Despite having one ear, its ability to hear sounds is well beyond that of a human, although they cannot discriminate the direction of a sound, nor its frequency. To this day, the praying mantis remains the only known animal in the world with just one ear.
Correct Answer: Praying mantis
