You will prepare and submit a term paper on Endangered Animals: Blue Whales. Your paper should be a minimum of 1250 words in length. The blue whale is the largest animal present in this world. in fact, even the dinosaurs were smaller in size than these whales. The largest ever known dinosaurs weighed 90 metric tons. The whales are so huge that no adult whale has been correctly weighed up till today, the whales are cut into measurable sizes and then they are weighted, in this way only approximate values of the weight can be observed but certain amount of blood and various fluids are lost during the cutting process due to which the actual weight could never be taken. It is approximated that the weight of one adult whale is 170-190 tons with an approximate length of 89feets (Palmer, Sarah, and David Palmer, 135).  .Several different species of the blue whales are present in different places of the world. The blue whales are generally present in all the oceans of the world. As compared to other species of whales this blue whale is more slender as compared to the stockier whales which are present in general. The different species of the blue whales are present in different oceans of the world. Some have their habitats in the South Pacific Ocean while some of the species reside in the North Pacific Ocean, while others are found in the Indian Ocean and the Atlantic Ocean as well. Therefore, in general, it is considered that the blue whale exists in all the oceans of the world. These blue whales although so huge and enormous feed on small creatures. Krill is the major part of the diet of any blue whale. These whales can eat up to 3600kgs of krill in a day. Seeing their huge sizes this amount of food is not that huge.
