Balaenoptera Musculus By Tristan Sirls Introduction • The blue whale is the largest animal to ever to live! Blue whales are part of family called rorquals. Most blue whales tend to call to other blue whales with low pitch sounds that can travel from South America to Africa. They have been recorded as songs on cd`s. The blue whale is a very interesting animal. Physical Description • The colors of a Blue Whale are pretty. They are slate or grayish blue with lighter spots dabbed on their back and shoulders. The average height of a blue whale is eighty five to one hundred feet. It has hair skin and blubber. The blubber helps the Whale not freeze. The Blue whale has a very unusual physical description. Habitat • The ocean is a great habitat for the blue whale. It is full of life and has tons of food for the whale. The ocean is a very cold place though. The Blue whale has no shelter and that is why it never sleeps. All blue whales live in the Antarctic Ocean because it has the most food for them. The Blue Whales habitat is very similar to the seals habitat. Diet • The Blue Whale eats a lot. It eats two tons of krill a day! The Blue Whale has installed filters in its mouth. They are called baleen plates and they have more than three hundred. The baleens filter the water and the krill come with it. Then the krill gets stuck on the plates. The Blue Whale licks the krill off the baleen plates. The Blue Whales mouth is about as complicated as my whole body! Life Cycle • Blue whales are mammals so they have live babies. The babies are usually born in low latitude waters. First two Blue Whales mate. Then they have a baby blue whale and keep it for a few, protecting it and feeding it and then they let it go free and as it swims and eats it gets bigger and bigger until is a adults. This process takes eight to ten years. Then the parents die of old age. This whale has a long life. Conclusion • Blue Whales are very interesting animals. I’m still amazed that you can swim in a Blue Whales vein. I have really enjoyed researching this animal. So when you see a huge whale going really fast, it might just be a blue whale. • Pictures of the Blue Whale.
