Do you know what the largest animal in the world who are still alive so that it can be seen directly and studied for materials research and knowledge?
No other is
Blue Whale (Blue Whale)
Blue whales are not fish but mammals are warm-blooded, breathe with lungs, give birth and breast-feeding her child. These marine mammals have the measure of weight and volume of extraordinary.
Spoiler for General Description:
Blue Whale (Balaenoptera musculus) is a marine mammal belonging to the suborder Pope Balin. Its length can reach 33 meters and weighing 181 tons. The animal was believed to be the largest animal that ever lived.
Blue Whale Habitat scattered to almost all the oceans until the 20th century. For more than 40 years these whales were hunted almost to extinction, since the year 1966 is protected by the international community. In the year 2002 there are an estimated 5000 to 12,000 in the Blue Whale is located around the world are divided into at least five groups. Before the hunt whales, the largest population in the Antarctic, with the number estimated 239,000 fish (202,000 to 311,000 to reach the tail). The rest hny small (about 2000 fish) concentrating on each group northeast Pacific, Antarctic, and Indian Ocean. There are two more groups in the North Atlantic Ocean and at least two in the South.
Blue Whale is Balaenopteridae Family, Family which includes the Pope bent, Fin Whale, Bryde's Whale, Sei Whale and Minke Whale. Blue Whale is usually classified as one of the seven species of whales in the genus Balaenoptera. Blue Whale has a long tapering body that indicates the field in comparison with other .his head whale's body is flat and U and has a striking back extending from the hole burst through the upper lip. The front of the mouth-shaped thick plates Baleen; approximately 300 plates (one plate pjgnya sktr 1 m) depending on the upper jaw, reaching 0.5 m which returned to the mouth. Between 60 and 90 grooves (called ventral plate) reaches of the esophagus in parallel to the body. These plates assist in moving the water from the mouth after eating movement. Blue Whale show shoulders and spat out the exit hole of water larger than other large whales such as Fin Whale (finches). This feature may be used by researchers to distinguish between species in the ocean. Some Blue Whale in the north Atlantic and north Pacific showed the tip of their tail when diving. When breathing, the pope issued a stunning burst of vertical (between 9-12 m) which can be seen from a distance on a sunny weather. Lung capacity of 5000 liters. Blue whales have a double burst holes, which are protected by a large protective.

Fins have 3-4 meters long. Side of the color barrier abu2 thin white dg. White bwh side. The tip of the head and tail are covered with color abu2. The top of the whale, and sometimes the fins, usually there is a bulge. Different levels of protrusion between masing2 individuals. Some may be closed entirely bluish color abu2, but others showed variations decent dark blue, and black abu2, all kinds of bumps. Blue whales can take kec.50 km / h, when interacting with other whales, but in general 20 km / hour. When eaten they moved slowly up to 5 km / hour. Blue whales typically live alone or with other individuals but an unknown faithful to their partners or ill. In places where there is food with high concentrations, a group with a number of Blue Whale approximately 50 tail has appeared to spread like a small wilyh.

Spoiler for Size:
Blue whales weighed difficult because of their size. Most of the Blue Whale whales killed by hunters who do not measure accurately, but it was cut into several pieces first. However, the measurement results is estimated between 150 and 170 tons (150000-170000 kg) with a length of about 27 m. The mass of a blue whale measuring 30 m long, is believed to have a mass of more than 180 tons (180,000 kg). Largest Blue Whale accurately weighed by NMML scientists to measure a female who weighs 177 tons.
Blue Whale is believed to be the largest animal that ever lived. Largest dinosaur known from the Mesozoic Era is Argentinosaurus, which is estimated to have a mass of about 90 tons. Pope's longest ever won two females measuring 33.6 m and 33.3 m respectively. However, the disputed measure. The longest whale measured by scientists at the National Marine Mammal Laboratory (NMML) America is 29.9 m. Proportions of length approximately 3-4 times the weight of school buses is proportional to the 25 adult elephants and / or more severe than Brontosaurus (as in the movie Jurassic Park)
Spoiler for Picture Illustration Size Comparison:
Blue Whale's tongue weighs around 2.7 ton & when fully opened mouth expected large enough to hold more than 90 tons of food and water. Heart of mass 600 kg & is the largest known of any animal, liver (liver) mass was 450 kg and the total weight of blood in the body of 6400 kg (6.4 tons) Blue Whale's aorta diameter of about 23 cm. During the first 7 months of her life, a young Blue Whale drink about 400 liters of milk every day. Blue Whale child gain weight rapidly, as much as 90 kg per day. Even at birth, they have a mass of 2.700 kilograms (just like the full growth Kudanil)
Spoiler for Food:
Blue whales feed almost exclusively is the krill, although they also eat small amounts of Copepod. Zooplankton species was eaten by a variety of Blue Whale from ocean to ocean.
Spoiler for Picture Paus3:
Paus2 are always eating in areas that have a lot of krill, sometimes eating between 2000-4100 kg of krill in one day. This means that they typically feed at depths of more than 100 m during the day, and eat only at the surface at night. When diving for about 10 minutes while eating, although diving more than 20 minutes are common. Recording the longest dive was 36 minutes. Pope was dining with a bunch right at paru2 krill, animal transport and a large amount of water in his mouth. The water is then pushed out to the Baleen plates by pressure from the pouch fins and tongue. Once his mouth clear of water, the remaining krill, unable to pass through the plate, then swallowed. Blue Whale incidentally also consume small fish, crustaceans and squid caught up with krill.

Spoiler for Reproduction:
Perkimpoian begins in late autumn, and continues until the end of winter. Little is known about the behavior perkimpoian. Females typically give birth once every two to three years at the beginning of winter after a gestation period of 10 to 12 months. Mass of approximately 2500 kg child (2.5 tons) and the length of about 7 m. Child Blue Whale 350-570 liters of drinking milk every day. Weaning process takes about 6 to 7 months, weighing about 23 tons and length of 14 m. Specifically sexual maturity reached 8 to 10 yrs by which time the male has reached the length of 20 m (or more in the South). Females were larger, reaching sexual maturity at around the age of five years, with the length has reached 21 m.
Scientists estimates that the Blue Whale can be aged up to about 80 years. Research longest recording a single individual is 34 years old, in the northeast Pacific. Natural predators for these whales is the killer Whale (Orca). Research reports that as many as 25% of adult Blue Whale has caused injuries Pope attacks murderer. Blue Whale circumstances deemed unusual and because the social structure of species (perhaps because of exceptional size and its water spray), when the whales approached the shore, they can become human attention. In 1920, the Blue Whale hunted on a large scale near Bragar, Isle of Lewis, the outer Hebrides of Scotland. This mammalian gut instinct to try to find a location to facilitate the breathing process by approaching the shore.

The level of the sound made by the Blue Whale between 155 and 188 decibels (a jet aircraft approximately 140 db).
