    BLUE WHALE (Balaenoptera Musculus)

    Choose from WHALES (CETACEAN) category:

    The blue whale is the largest known animal to have ever lived on our planet. The heart alone weighs 600kg and is about the same size as a Volkswagen beetle car and even a small child could crawl through the Aorta (the main artery of the heart). They feed mainly on krill, which is somewhat like a small shrimp or prawn and can eat up to 4000kg a day. They are also one of the loudest animals on the planet getting to levels of 188db compared to a 747 jet engine at 140db. Unfortunately they were almost hunted to extinction as about 360,000 were killed between 1900-1960 alone. We started seeing this species regularly in October 2011 from Grindavik, thought to be those migrating down from the north.
