Facts about the Blue Whale

  • The blue whale is, by far, the largest mammal on the planet. And is a carnivore.
  • They can weigh up to 200 tons, equivalent to 30 T-Rex‘s or roughly 30 elephants (for more modern measures); however, the average weight of a blue whale is 115 tons, still the weight of many elephants.
  • Their tongue itself weighs as much as an elephant and their heart as much as a car.
  • They are also known to grow up to 100 feet long, about two times as tall as The Hollywood Sign, or two semi-trailers (one is ~48 feet long).
  • They have a very long lifespan. They can live from 80 to 90 years, almost a century.
  • Strangely, they feed on little shrimp-like creatures known as krill, even though they are large enough to eat a shark.
  • During certain times of the year, a blue whale can eat up to 4 tons of krill a day.
  • They are colored blue, as to why they are named the blue whale.
  • Millions of microorganisms live on the whale’s underside, causing it to look yellow.
  • They live in the world’s oceans and they will migrate to a warmer area as the weather gets colder.
