The blue whale

The blue whale

The largest animals ever been to earth are still living today. The blue whale is much bigger than the largest dinosaurs one. Everything about the blue whale is big! Even its tongue may weigh up to four tonnes. They also call to each other in big voices which can be heard over 800 kilometers away. They are easily the loudest creatures. Because they are mammals,blue whales breathe air. This means they must come to the surface of the ocean to breath. The water spout a whale blows out is not really water at all-it is hot breath and water vapour. Mother feed their young on milk. By the time they are a year old,the young calf may weigh more than 20 tonnes. They can live up to 45 years.
