Why is blue Whale special ?
Blue Whale, as most of us know, are the largest animals that ever existed Earth. They are incredibly huge and weigh as much as 150,000 kg, which is almost equivalent !.
Blue Whales are known to be found worldwide. Larger individuals grow up to 33.5 meters in length. Typically they have longs bodies with mottle gray color pattern that appear to be light blue when see through water. Krills, a kind of small crustacean, form the major diet of Blue Whales. These marine animals can eat about four tonnes of krills every day.
There are numerous other interesting facts about Blue Whales, but the saddest one is that they are endangered. The animals were almost extinct at a point, when the International Whaling Commission declared them a protected species in 1966.
The main threat then was commercial Whaling, but today, it is climatic changes. The changes in marine environment have badly affected krillls, and this is turn, has led to a fall in the Blue Whale population too. The presence of toxic substances in waters is another factor contributing to this.
