Which is the largest species on planet?

 The Blue Whale is not only the largest animal species in the world but it is also thought that it could be the biggest creature that has ever existed with some individuals growing to more than 100ft long. Since the Blue Whale is the largest animal on the planet meaning that numerous organs are much, much bigger than those found in any other animal. In just one breath from a fully grown adult Blue Whale, will produce enough air to fill nearly 2,000 balloons! Also, the heart of the Blue Whale is so big that it is around the same size as a small car, with their main arteries being big enough for a human to swim through comfortably! Being mammals, Blue Whales must come to the surface to breathe in air but also have to expel it and do so by blowing all of the warm, humid air and sea-water out of their lungs through their two blow-holes and into the air. Blue Whales do this with such force that this column can shoot as high as nine meters into the sky. In the summer months, Blue Whales are found in the cold waters of the Artic and the Antarctic  where they feed on the abundant amount food, before moving towards warmer, less-rich waters for the winter when they breed.The noises Blue Whales make are incredibly loud and having been recorded at volumes greater than 180 decibels, they are known produce the loudest sound of any creature on the planet.  The Blue Whale is a carnivorous animal that despite the fact that it doesn't have proper teeth, survives on a diet that is mainly comprised of  small fish.
