The blue whale
The largest animals ever to have been on the earth are still living today. The blue whale is much bigger than the largest dinosaur one.
Blue whale measured nearly 34 metres and weighed more than 220 tonnes! 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 kilometres. They are easily the loudest living creatures.
Because they are mammals, blue whale breathe air, this means they must come to the surface of the ocean to breathe. The “waterspout” a whale blows out is not really water at all - it is hot breath and water vapour.
Mothers 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 for up to 45 years.
