I have listened this video for 10 minutes
Blue whale is a marine mammal which live in Pacific Ocean .With 33.59 metre length,189 metric tonnes weight ,blue whale is the biggest animal in the world. What's more, it is very atonshed that its lung capacity is 5000 litres! Every day,about 1 tonnes of krill and crustacean are eaten by a blue whale. In late fall, it mating starts,and continues to the of winter.Due to unreasonable hunting ,the number of blue whale has drawn to 5000 to 12000 in the world. So many orgnizations are founded to protect them. If we go on hunt them unreasonably, our grandson will never see them! So something must be done by us.

New word:mammal n. worm-blooded animal ,such as humen, rodents,carnivores, bat
E:The bat is a flying mammal
I think blue whale is so cute .Its face like a kid's.But when I heard about it is emdangered animal,my feel was sad. So I chose this one.
