Morning Starters: Summer 1 - Record Breakers
Clip Description
The sperm whale holds the title for being the loudest animal on the planet. It produces powerful clicking sounds with an intensity reaching up to 230 decibels. (This level of sound is greater than that of an airplane jet engine, which is about 150 decibels.) These clicks facilitate echolocation and communication, aiding the sperm whale in the navigation of the deep ocean and the predation of prey such as giant squid.
