Curiosities: What is the biggest animal in the world?

By Eddy Montilla.

Because of all my mistakes that I make every day, I had my doubts on the subject, but now I can sleep peacefully knowing that I am not the biggest animal in the world. It is the blue whale, the largest existing animal today and the largest animal ever known to have lived on Earth. This animal can measure up to 30 meters in length and weigh about 200 tons. Even at birth, blue whales are already among the largest animals if you take into consideration that during the first months, a blue calf can approximately drink 400 liters of milk every day and it also grows and gains weight quickly, as much as 90 kilograms every 24 hours. Due to its size, any part of its body is big. For example, its tongue (around three tons) can weigh as much as an Asian elephant. Despite its size, it is interesting to note that blue whales live almost exclusively on tiny animals called krill. They can eat up to 4 tons of krill in a single day.

     Finally, the blue whale is not as blue as it looks inside de water. Actually, on the surface its coloring is more a mottled blue-gray. It is estimated that blue whales can live for at least 90 years, but taking into consideration that they are animals in danger of extinction, the damage caused by man to the environment and the predatory hand of man, I wonder whether they can reach that age these days.
