Blue Whales: Giants of Earth

Blue Whales: Giants of Earth

The blue whale is not only the largest animal to have ever existed on Earth, it's also the loudest. This mammal's low-frequency calls measure around 200 decibels (a jet plane takeoff is around 140dB). However, the pitch of the call is so low, it's beyond human hearing.
