Evolution Of Whales - The Dr. Binocs Show | Best Learning Videos For Kids | Peekaboo Kidz

Whoa! Oh goodness me! Did you see that, friends? That was one giant animal! Or should I say, that was one giant whale! So kids, let us enter the enormous world of whales.. ..and learn some interesting facts about these largest species in the world. Zoom in! So friends, I'm sure that you already know that whales are the largest animals.. ..ever lived on the planet Earth. Even bigger than the largest dinosaur. But, you will be surprised to know that it is believed.. ..that millions of years ago, whales were land animals. Yes, they probably walked upon the Earth. The first whales were known as Pachysetus. Their skulls were long with large carnivorous teeth. I know you guys must be wondering that they don't even look.. ..remotely close to their present avatar. But, if we examine closely at their skulls, especially in the ear region.. ..which is surrounded by a bony wall, it strongly resembles those of existing whales.. ..and is unlike any other mammal we have seen. As these creatures entered the water, their hind legs disappeared over time.. ..and their front legs evolved into flippers. Just like my moustaches evolved into hands. Never mind. Coming back to our giant relatives known as whales. Yes, I'm calling them relatives because just like humans.. ..whales are mammals and not a fish like we popularly believe. And like most mammals, they feed milk to their babies.. ..and breathe air for oxygen through their nose. I know you guys are alike, but whales don't have noses. Of course, they don't have a nose as you do. But, if you look closely, they have a hole on top of their heads.. ..and it's called a blowhole. Blowholes are surrounded by protective muscles.. ..and they only open it when whales are at the surface and needs to breathe. Sometimes, when a whale exhales from its blowhole.. ..it shows up as a spray called a spout that can be viewed many miles away. Trivia Time! Did you know that the largest known whale to ever exist.. ..has been known to grow to lengths of 70 to 90 feet long.. ..and can weigh up to 150 tons. Whoa! I would never like to wrestle a whale even in my wildest dream. Not only that, blue whales are the loudest animals on the planet. Their cries can be louder than a jet engine. Whoa! I would never make a whale cry as well. So, here we go friends. Hope you are amazed by these facts about whales and learnt something new. And before you go, I have something new for you as well.
