Close up of the biggest animal in the world

Blue whale (mackerel) is a mammal that lives in the oceans.

They live in all the oceans on earth.

Blue whale is the largest animal living on earth. They are three times bigger than T-rex dinosaurs and 1.5 times longer than long-necked dinosaurs.

Their average body length is 25 m (male) and 26.2 m (female). The longest blue whale was discovered in 1909 in the southern Atlantic Ocean. Its length is 33.58 m.

Even newborn blue whales are giant animals, with a length of 6-8 m and a weight of 2-3 tons. They feed about 200 liters of milk and increase to 9 kg per day.

Although large, blue whales mainly eat krill - small zooplankton belonging to crustaceans. Each child eats about 5.5 tons of krill every day. Since each krill weighs only 1 gram, whales must swallow 5.5 million krill everyday.

The skin of the blue whale is grayish green, with a lot of light colored abdominal skin. They have two side swimming fins 2.4 m long.
