Beluga #whales have a distinctive protuberance at the front of their heads called a melon — this compartment houses their echolocation organ. A beluga’s melon is malleable, meaning its shape is changed during the emission of sounds. They are even able to change the shape of their head by blowing air around their sinuses to focus the emitted sounds! 🐳 | Science Channel
