Hello everyone! My name is Billy the Blue Whale. I am the largest and heaviest animal on earth! I weigh over 100 tons. I’m heavy, but I love to swim. I live in the ocean and I love it here. But I don’t go to the Arctic because it’s too cold! I can eat some of the tiniest animals in the ocean. I can eat several tons of them every day.
Complete your passage about the blue whale based on the text in 3a.
Did you know I can live up to 90 years That’s about as long as humans! When my life ends in the ocean, my body becomes a super important buffet for animals living in and around the sea. By helping so many animals survive, I keep the ocean happy and healthy. That’s why humans need to protect my whale family.
