The sensory organs receive stimuli from the environment and transmit them to the cerebrospinal system. ... Each of the three sacs contains a calcareous nodule called an otolith, which increases in size throughout the entire lifetime of the fish due to the deposition of salt, mainly calcium carbonate.

The three semicircular canals are known by their orientation: anterior, posterior (the longest), and lateral semicircular canals.
Webb摘要： Detecting low-frequency underwater acoustic signals can be a challenge for marine applications. Inspired by the notably strong response of the auditory organs of pectis jellyfish to ultralow frequencies, a kind of otolith-inspired vector hydrophone (OVH) is developed, enabled by hollow buoyant spheres atop cilia.
