1. Information on Blue Whales English Version
Blue whales are not only the largest whale species, but also larger than the largest dinosaur that once lived on Earth, the Velociraptor (which had a body length of 39 to 52 meters! It can reach a height of 18 meters and weigh up to 130 tons). It is currently the largest known animal from ancient times to the present day, with a body length of 2400-3400 centimeters and a weight of 150000-2001000 kilograms. In other words, its weight is equivalent to the total weight of more than 25 African elephants or 2000-3000 people. Fortunately, due to the buoyancy of the ocean, it does not need to struggle to support its weight like terrestrial animals, and its large body also helps maintain a constant body temperature. The entire body of a blue whale is pale blue or mouse gray in color, with small pale markings on the back and white spots on the chest. There are more than 20 folds and grooves, and the abdomen is also covered in folds, reaching up to the navel and with yellow spots of ochre color.

There are up to 300-400 on each side, with a length of 90-110 centimeters and a width of 50-60 centimeters.
