Balaenoptera musculus, the blue whale, is the biggest creature at any point known to have lived in the world, including all dinosaurs. It is larger than adults of most other animal species, even at birth. The planet is covered with astounding, capivating animals, yet the blue whale is really amazing. Thing about the following:

1. Blue whales are enormous and can reach lengths of more than 100 feet. The longest ever recorded was a magnificent 108 feet (33 metres). That is probably upto three school transports arranged from start to finish.
2. They can weigh as much as 30 elephants. The typical load for these delicate goliaths is 200,000 to 300,000 pounds (90,000 to 136,000 kilogrammes), or around 100 to 150 tonnes. Some can weigh as much as 220 tonnes, or 441,000 pounds (200,000 kilogrammes). An adult African bush elephant can weigh up to 6 tonnes, so it cloud take 30 or more elephants to equal one blue whale's weight.
3. They have large hearts.           The blue whale's heart is immense. It's the biggest heart in the set of all animals, weighing around 400 pounds (180 kg) and generally the size of a crash mobile. It's possible that a blue whale's enormous heart only beats twice per minute as it dives to eat.
4. They have enormous tongues as well. A blue whale's tongues alone can weigh as much as certain elephants.
5. They have the biggest babies on Earth. The calves of blue are easily the biggest babies on Earth. At birth, they already rank among the largest animals that are fully grown. They have a length of about 26 feet (8 metres) and weigh about 8,800 pounds (4,000 kilogrammes) when they emerge. Everyday, they gain 200 pounds (90 kg). With a several billion-fold increase in tissue from conception to weaning, their growth rate is likely one of the fastest among animals.
6. They're Curiously Clearly Blue whales, truth be told, are the most intense creatures on earth. 140 decibels are recorded by a jet engine; a blue whale's call reaches 188. Others up to 1,000 miles (1,600 kilogrammes) away can hear their pulses, groans, and moans.
7. They consume a great deal of krill. Blue whales consume krill. The tiny crustaceans can be carried in their stomachs up to 2,200 pounds (1,000 kilogrammes). During the summer feeding season, they require approximately 40 million krill per day. Or almost 9,000 pounds (4,000 kg.
8. They are quick.                           They travel a great deal, spending summers taking care of themselves in polar districts and making the long excursion to the equator as winter goes along. While they have a curising pace of 5 mph (8 kph), they can advance rapidly up to 20 mph (32 kph) when required.
9. They live a long time. Blue whales are one of the animals that live the longest in the world. Similar to counting tree rings, researchers include layers of waxing in the ears and can determine a ballpark age. The avarage lifespan of a blue whale is throught to be between 80 and 90 years, but the oldest on they've found in this way was estimated to be around 100 years old.
10. They Were Common Previously, the species fo common before whalers discovered oil that blue whales could provide. However, as whaling fleets emerged in the 20th century, their population plummeted until they finally received worldwide protection in 1967. From 1904 to 1967, a larger number of than 350,000 blue whales were killed in the southern half of the globe, as per the World Untamed Life Asset. During the peak of whaling in 1931, 29,000 blue whales were killed in one season.
11. While commercial whaling is no longer a threat, blue whales are still in danger from ship strikes and the effects of climate change, and recovery has been slow. There is a single population of approximately 2,000 blue whales off the California coast, but there are only approximately 10,000 to 25,000 individuals remaining overall. The species is listed as endangered by the International Union for the Conservation of Nature. It is hoped that in time, the planet's gentle giants will once again frequent the seas.
