From the BBC’s Ocean Giants documentary, watch this incredible clip to hear the extraordinary and mysterious song of the Humpback Whale. Why do they sing (or hum)? Does it serve a purpose? Are they making music for pleasure? Are they talking?
If this clip disappears, you can find the entire documentary on Amazon. And in the archives: watch more whale videos, including a surprise diving encounter with a Humpback Whale, this huge baby Sperm Whale, and Whale Fall (After Life of a Whale).
