The blue whale is a sea creature. There are different kinds of whales.
Blue whales are not only the largest sea creature they are also the largest known creature on this planet. The biggest blue whale ever measured was a female,who weigh over 190 tonnes and was 33.5 meters long. Blue whales got their name from their colour.
Blue whales give birth to some of the largest babies in animal world. New born calves are 7 to 8 metres long and can weigh up to 4 tonnes. Blue whales and other whales eat fish. But Blue whale calves drink over 350 liters of fat rich milk gaining up to 90 kilograms.
Unfortunately the blue whale is now one of the earths many endangered species. I hope people look after these blue whales.
