Galleria Mellonella: At 300 KHz, Greater Wax Moth Is The World's Most 'Extreme Hearing' Animal

Galleria Mellonella: At 300 KHz, Greater Wax Moth Is The World's Most 'Extreme Hearing' Animal:

Humans are only capable of hearing sounds from 20 Hz up to around 20 kHz maximum and that drops as we age, while our pets can hear at higher frequencies (leading to concern about things like the hum from ballasts in CFL bulbs) but even dolphins, famous for their ultrasound, only cap out at around 160 kHz.
