Balaenoptera Musculus, or the blue whale, is the largest mammal in the world. This enormous mammal can grow to be 110 feet long and weigh as much as 190 tons. That's longer than two city buses and the total weight of 30 elephants. This giant is powered by a heart the size of a taxi-cab. The blue whale's of the Antarctic grow larger than those of the Northern Hemisphere. Also, the females tend to be slightly larger than the males of the same age. These mammals are bluish-gray in color, with some paler spots. Algae tends to accumulate on their bellies causing a yellowish or mustard color. It has a mottled appearance with a broad, flattened U-shaped head. Fifty to ninety throat grooves run from…show more content…
Sometimes the whale arches its tail stock, but often simply sinks below the surface.
The blue whale can accelerate to speeds of over 19 miles per hour when it is being chased, but usually he swims much slower. Adult whales rarely, if ever, breach clear of the water. Youngsters, however, have been observed breaching at an angle of 45 degrees, and landing on their stomachs or sides.
Blue whales are close knit and are usually found in groups of 1-5. You may see up to 30 whales gathered at the feeding grounds. Most feeding seems to take place during the evening and early morning. The whales produce ultrasonic chirps and whistles when feeding. They use a low frequency moan to call to each other.
This mammal uses its powerful muscles in the tail to drive the great fan-shaped blades (flukes) up and down to propel itself through the water. It takes him very little energy to swim. Their bodies are designed better than man-made missiles or submarines. They have a fine oil that lubricates their smooth, thin skin and reduces friction. Blue whales have extremely flexible and marvelously streamlined bodies that help them glide through the water without a ripple. Their bones are light and spongy, making them naturally buoyant. They neither rise nor sink, but can stay at any given depth without any effort. Dorsal fins and flippers give the whale
The Effect of Over Hunting on Blue Whales

The blue whale can eat up to 4 tons of krill in one day, and live up to 90 years old. Blue whales can make sounds and tones that travel up to 1000 miles away. Blue whales are so big and take up so many resources that have to live in small groups of one or two called pods. The Blue whales habitat ranges between Madagascar and Antarctica. In 1904 there used to be close to 400,000 blue whales living on earth, but now due to over hunting people have put the human race in danger along with the blue whale species.
The history of whaling originates all the way back 3000B.C. Whaling is killing whales for meat and oil. Huge fleets of whalers did not come around until the 1700’s. By the 1930’s 50,000 whales were being killed annually. From 1904 to 1967 360,000 blue whales were killed, that adds up to about 70% of their population. Whales produce up to 3 off spring at most in one year so the bounce back from a huge killing would take many years. The International Whaling Commission was established in 1946, to help fight commercial whaling.
The IWC came around to help fight whaling, but they had little effect. In 1970 the Convention of International Trade of Endangered species put a ban on all whaling. Even though there is a ban on whaling Norway, Iceland, Japan and the USSR still have whaling fleets but under the name of “scientific research”. The only people who are…
