Every Whale Explained in 18 Minutes

Every Whale Explained in 18 Minutes Beluga whale. The beluga is basically the ocean's living smile wrapped in pure white skin. Adults are completely white, almost glowing against dark Arctic waters, though they're born gray and slowly fade over their first five years. They're one of the smallest whales, reaching about 13 to 20 feet long, but what they lack in size they make up for in personality. Belugas are called Arctic canaries because they're the most vocal whales on Earth, producing clicks, whistles, and chirps that sound like an underwater bird choir. Unlike most whales, they can actually turn their heads thanks to unfused neck vertebrae, giving them a flexibility that makes them look curious and playful. They use echolocation so precise it can detect fish buried under sand, and they live in social pods of 10 to 25 individuals, sometimes merging into groups of hundreds. But life in the Arctic is getting harder. Melting ice reduces their habitat, noise pollution disrupts their echolocation, and some get trapped when ice freezes too fast. Still, their expressive faces and constant chatter make them one of the most unforgettable whales you'll ever encounter.
