How to Speak Walrus

Leah Combs, a trainer, and Colleen Reichmuth, a marine biologist, introduce us to three very charismatic walruses who are teaching scientists much about walrus vocalizations and communications. In this audio slide show, meet Siku, Uquq, and Sivuqaq and hear the remarkable range of sounds they produce both above and below water.
