Blue Whale, The Largest Mammal In The Ocean


Blue Whale (Balaenoptera musculus) is a suborder of marine mammals that accompanies Pope Balin. their length reached more than 33 meters and a mass of 181 metric tons or more, it is believed to be the largest animal that had in his whole life though some dinosaur discoveries separately like colossal might Amphicoelias fragillimus challenges the belief that last a long time.


Blue Whales are very abundant in nearly all oceans until well into the 20th century. For over 40 years whales were hunted almost to extinction by whaling until protected by the international community in 1966. A 2002 report estimated there were 5,000 to 12,000 Blue Whales worldwide located in at least five groups. Most current research draws attention to the Little subspecies may under estimate. Before whaling, the largest population was in the Antarctic, numbering approximately 239,000 (202,000 to 311,000). The rest is only a small portion (approximately 2,000) concentrate in each group of northeastern Pacific, Antarctic, and Indian Ocean. There are two more groups in the north Atlantic Ocean and at least two in the Southern Hemisphere.

Like other mammals, whales also feeding her child. But the baby does not suckle its mother whales because they are at risk of swallowing seawater. As mentioned previously, sea water is harmful to whales. Interestingly, like dolphins, there are muscles that surround the female mammary glands of whales. When a whale is moving a muscle, the resulting pressure makes the parent is able to squirt the milk directly into baby's mouth. Whale's milk is different from the usual we are familiar. Shaped almost like a solid and very fatty. Because his form like that, breast milk can not be mixed with sea water. Substances that are taken or rather eat baby whales will be dissolved in the stomach. These foods also contain dissolved water needed by a baby whale.
