    1. BLUE WHALE by Alston Yan

    2. Food Chain The Food Chain of a Blue Whale is that the Blue Whale eats zooplankton[Small crustaceans] and then the zooplankton eats the phytoplankton.

    3. SCIENTIFIC NAME The scientific name for the Blue Whale is called Balaenoptera Musculus.

    4. SIZE Blue Whales are the biggest animals ever known to man kind. They are even bigger then the dinosaurs. The biggest Blue Whale ever to be caught was a female Blue Whale. It was 29 metres long and weighed more then 158 tonnes. Also, female Blue Whales are bigger then the males and their blood vessels are so big that you could swim in it.

    5. How much a whale eats a day and what it eats! The Blue Whale eats plankton, krill zooplankton and copepods mainly for its diet. An average sized Blue Whale would eat up to 2,000 to 9,000 pounds of food a day. Blue Whales eat a lot so they can store the food in them to survive the Winter. Also it eats mainly in Summer in the Artic Region where food is rich and plentiful.

    6. VOCALIZATION Blue Whales are the loudest animals alive beside the fact that they are the biggest.The sound of a Blue Whale is louder than a jet engine. The Blue Whale uses its high pitched voice to attract a mate. The voice is also used for locating krill to eat.

    7. BREATHING Whales breath through two water holes near the top of their head. Wales spout [breath] about 1-4 times a minute at res. After a deep dive, they spout about 5-12 times a minute. Their spout is a stream of water that rises 12-15 metres from the surface of the ocean.

    8. PREDATORS There are not a lot of predators for the Blue Whale because of its size. The main predators are the Killer Whales that hunt in packs, and humans. The pack of Killer Whales try to drown the Blue Whales and the humans hunt them. Blue Whales use to be endangered because of human hunting and now whaling has been band in all countries except for Japan. There are currently 10,000 Blue Wales world wide.
