Perceptor horns, alternatively referred to as cones or perceptor cones, served as extra-sensory organs present on every member of the Gotal species. These cones enabled Gotals to both broadcast emotional waves and perceive the "vibrations" emitted by other living beings. While functioning as typical cones on Antar 4, underdeveloped cones were a source of mockery.
