Hello everyone! My name is Benny the Blue Whale. I am the largest and heaviest animal on earth. I can weigh as much as 200 tons. I’m really big, but I love swimming in the oceans. Many people like watching me swim and say it’s one of the most beautiful sights at sea. I live in all oceans except the Arctic Ocean.

Hello, everyone! I'm Willy, a blue whale. I'm proud to be the biggest and heaviest animal on Earth. Can you believe I can weigh up to 200 tons That's like having hundreds of cars stacked together!
I swim freely in all the oceans around the world, except for the freezing Arctic Ocean. The water there is just too cold for me. My home is full of amazing creatures, and I especially love feasting on the tiniest animals in the ocean. Every day, I eat around four tons of them to keep my big body going.
Even though I'm huge, I love moving through the water. The ocean is my playground, and I enjoy showing off my swimming skills. I hope people will keep our ocean clean so that I and all my friends can live happily here forever.
