The Antarctic Blue Whale is the biggest animal living on planet earth. It can measure up to 100 feet in length and can weigh around 150,000 kilograms. Compared to blue whales, the average height of humans is under 6 feet. Here are some interesting facts about the blue whale.
Antarctic Blue Whales Are Endangered
The blue whales might be the biggest animals, but they are also among the most endangered species on our planet. Their colossal size has not been able to deter humans from hunting them down.
The blue whale population has sharply fallen from 1.25 lakh in the 1920s to around 3000 as per the census in 2018.
Commercial whaling resulted in the mindless killing of these mammals. To save the remaining whale population, they have been classified as a ‘critically endangered species’ and have been given protected status.

Blue Whales Feed On Krill
For an animal so huge, the staple food of blue whales are krills, one of the smallest of sea animals. Krills are from the crustacean family of species living underwater.
They are found in most oceans and are the primary food source for several animals, including penguins, seals, and whales. The blue whale can eat between 3 and 4 tonnes (4,000 pounds) of krill in a day. Their sightings often coincide with places abundant in krill.
They Are Very Loud
The blue whales also pack in very high decibels when communicating with other members of their tribe. They are, in fact, among the loudest species on earth. Sounds made by the blue whales can go up to 188 decibels.
Their sounds can be heard by other whales hundreds of kilometres away. Compared to a blue whale, the sound of a jet engine measures between 120 and 140 decibels.
Conclusion
Except for the Arctic Ocean, blue whales are found in most seas and oceans. They are migratory beasts and can swim at the speed of 8 km per hour and ramp it up to more than 30 km per hour.
The Antarctic Blue Whale is a majestic animal that has been made vulnerable in numbers because of rampant and illegal hunting. Blue whales can live up to the age of 90 years. We need to protect the blue whale, the largest animal surviving on earth.
