Blue Whale Facts

The blue whale is the largest animal on Earth. It usually reaches up to 30 meters in length and it weights almost as 2000 people or 30 elephants. Its heart only weights 700 kg and it is one meter long. The tongue of the blue whale weights 3 tons and there are 8000 liters of blood circulating in its body. Because of its heavy body, the blue whale doesn't swim very fast, but it can reach 35km per hour. The largest whale on the planet is part of the baleen whales category.

Although they hunt in very deep waters, the whale has to reach the surface for breathing air. The air is exhaled with pressure which creates air jets of almost 6 meters. because of its dimension, the blue whale has

become the main pray among the whale hunters. After they were killed, their body is turned into fat which was used in cosmetic industry. Early hunters could not catch blue whales easily because of their speed and power. Right whales or sperm whales were much more easy to kill, but after bigger harpoons were invented, they became the main target for the hunters. Between 1930 and 1931 more than 300,000 blue whales were killed. Since then, their number gets smaller every year, although several organizations are trying to protect the whales all over the world.

Whale babies are born every 2-3 years and they have between 7 and 8 meters at birth and a weight 3 tons (almost 1000 human babies). They eat milk for about 8 months and during this period they can reach up to 23tons.

Being part of the baleen whales species, the blue whale feeds on krill and small copepods, small fish or crustaceans. The blue whales do not eat bigger fish like the orca whales for example, because they don't have sharp teeth. Another fact about the blue whales is that they don't have any predators. The only enemies of the blue whale are the humans who almost brought them to an extinction.
