Any organism that has receptors to detect incoming vibrations can hear and gather information about their surrounding environment.
  • Varies depending on insect but often very high frequencies.
  • Moths, cicadas and grasshoppers have tympanic membranes on their abdomen to detect sound similar of that to the human ear drum.
  • Mosquitoes have hairs on their antennae, which detect minute vibrations in the air.
Bees, ants and termites have mechanoreceptors on their legs, which detect sounds travelling through the ground.
  • Ears are located inside their body.
  • 2 internal ears filled with fluid and lined with cilia.
  • The cilia detects movement of fluid within ear caused by vibrations.
  • Some fish also have a swim bladder filled with air which is able to detect sound.
  • Ears located on exterior of body.
  • Consists of three main sections.
  • The external ear, where vibrations are collected.
  • The middle ear, to transmit the vibrations.
  • The inner ear where the cochlea receives the vibrations and converts them into electrical impulses.
Similar within all mammals both terrestrial and aquatic.
  • Vibrations heard through Air and solid-ground.
  • Contains Tympanic membranes, hair cells and mechanoreceptors.
  • Vibrations heard through water.
  • Contains swim bladders, internal ears, lateral line systems, neuromasts and hair cells.
  • Vibrations heard through air and liquid.
  • Contains cochlea, hair cells and organ of corti.
