how much does a whale weigh
This whale on average grows to be around 9 ft. long and when fully matured will weigh between 400 â 600 pounds. In comparison the blue whale (the worlds largest living animal) can grow to a length of over 100 ft. and weigh in excess of 150 tons. The blue whales heart alone can weigh as much if not more than a fully grown dwarf sperm whale. In fact some of the largest blue whales have had hearts that weigh as much as 2,500 lbs., which is equivalent to the weight of a small car.
