The blue whale


Huge blue whale or whale (Balaenoptera musculus) is the largest mammal that ever lived. It is more surprising as the food offered in many ocean species, it feeds on most small plants(phytoplankton) and the smallest living organisms (zooplankton) feed that is called plankton.
Even if it hunt in deep waters, the whale  bounds to surface to get air. Expired air pressure is removed, which causes jets of even six feet tall.


Evolutionary concept states that, like other land mammals, and it comes in blue whale aerial mammals (scientifically proven). Millions of years ago, probably spurred an abundant food in the water, and there for the constitution would be changed rapidly.
Although practically could move freely anywhere in the sea,spreading its area is reduced to only on certain regions. This is because there are few places in the world oceans where is plankton issufficiently available.


Blue whales live in relationships, which can be seen frequently in groups of two to four copies. During hunting or reproduction the blue whales are formed in larger groups.

Mating occurs in tropical waters.This specie  at birth haves approximately seven feet in length and a weight of two-three tons.Being a marine mammal, breast-feeding small whales takes place all in the water. The baby sucks more
than 600 litres daily, until the age of two months and a length of 15 metres.

Feeding and hunting

In the Antarctic whales consume exclusive floating crayfish and Antarctic’s krillics.The study of the stomach of whales have been found 450 kg of krilli. In the waters of the North Pole it feeds with three species of crayfish.

In the frozen water oxygen and carbon dioxide, quantities are higher than in tropical waters,meaning there are a lot more species that lives there.
Contrary to its size, whale’s swims quickly, which can reach even the speed of 10-15 knots. Nutrition and a power of Attorney in particular to the immersion.Can spend even two hours at a depth of 500 metres. During the exit to the surface they make they’re way through the cloud of plankton, swallowing large quantities of water.
