What is a whale?

Did you know the biggest animal to ever live on planet Earth isn't a mighty dinosaur? It is alive today and swimming in our oceans! Join Mira and Finn as they dive deep into the fascinating world of whales and dolphins. Discover the incredible Antarctic Blue Whale, a gentle giant so massive that its heart is the size of a golf cart! But wait, if whales live in the ocean, why do they have to hold their breath underwater? You won't believe the answer! We'll travel back 50 million years to meet Pakicetus, a bizarre, wolf-like land creature that was actually the ancient ancestor of all whales. Plus, find out exactly how these ocean giants talk to each other in the dark. From humpback whales singing beautiful 30-minute songs, to sperm whales using the loudest clicks on the planet to hunt giant squid, their sonic superpowers will blow your mind! We’ll even learn how whale poop gives humans the oxygen we need to breathe, and how dolphins invent special names for their friends. Get ready for an underwater adventure!
