Blue whales are enormous creatures as we all know with a heart the size of a Volks Wagon beetle and weighing 600kg . Their tongue weighs 2.7 tonnes roughly the same as my truck. Its mouth is large enough to fit 90 tonnes of water. They travel at speeds of five to eight miles an hour the same speed as an old lady in a Nissisn Micra , and can accelerate to over 20 miles an hour which is the same as an old lady in a Nissan Micra who is going to be late for mass. They are the loudest animal in the world emitting groans and moans that travel up to 1000 miles away. Their calorific intake in a single day is equivalent to a bus load of American tourists after stopping at a Mac Donald’s for a snack before dinner, 1.5 million calories.
