Among the animals listed, the praying mantis is the only one that has only one ear, not the Lemur, Manatee, or Chameleon. Praying mantises have a single ear, known as a tympanic ear, located on the underside of their body, just below where their legs attach. This unique auditory system allows them to detect ultrasonic signals emitted by bats, their main predators, aiding in their ability to evade capture. In contrast, lemurs, manatees, and chameleons possess two ears like most mammals and reptiles, each adapted to their specific environmental needs. Therefore, the praying mantis stands out as the animal with just one ear among the options provided.
