Question

Quizplus · Accepted Answer

The ability to echolocate requires specialized sensory receptors, which dolphins and bats possess, but humans do not. While glossopharyngeal and vagus nerves may be involved in some aspects of echolocation, they are not a defining characteristic. Thalamic input from sensory receptors is a general sensory processing pathway found in most animals, not specific to echolocation. The ability to navigate in water or air is also not unique to echolocating animals.
