Can you imagine? In the real world, there are larger creatures than godzilla and king kong, not monsters in movies, but real marine mammals -- blue whales。

Let's look at 10 interesting facts about blue whales。
1. Blue whales can grow up to 100 feet (30 metres)
The blue whale is the longest known body on earth, typically 80 to 100 feet. However, there have been reports of blue whales over 108 feet long! This is to connect the three standard school cars to the size of the blue whale

2. Their weight equals 30 elephants
Blue whales are at the top of the masonry list. They weigh an average of 90,000 to 136,000 kg, or about 100 to 150 tons. In other words, the weight of a blue whale is equal to the sum of more than 30 adult african elephants (one adult african elephant can weigh 6 tons)

3. The heart of the blue whale
The heart of the blue whale is the largest in the animal world, weighing up to 400 pounds (181 kg), corresponding to the weight of gorillas. It provides power to the large body of the blue whale, whose heart rate can drop to twice a minute while diving. Can dive deep to 510 meters。

4. Blue whale tongue
According to statistics, the mean weight of blue whale tongues can reach 2. 7 tons, which is almost the weight of an african elephant

A young blue whale can weigh as much as 4,000 kg (4 tons) and be as big as 8 metres
6. The most loud voices in the world
The sound of the aircraft was approximately 140 db. But the deep-sea whaling of the blue whale can reach an amazing 180 db. This shocking voice can be heard by other blue whales up to 1,600 kilometres away. Beijing is about 1,000 kilometers from shanghai
7. Disgusting consumption
The krill is the main food source for blue whales, whose stomach can easily swallow 1,000 kg (1 ton) of krill. Blue whales spend 10 to 12 hours a day filtering and ingestion of about 4,000 kg (4 tons) of krill to maintain normal metabolism。
Krill is rich in fat and protein
8. Physical health
Usually, they can be up to 8 km/hour per hour. The speed of an hour can surge to 32 km/hour when it is necessary to avoid predators or catch prey. This is due to the millions of years of fluiding and powerful muscles of blue whales。

9. Life expectancy
Just as the age of the trees is judged by years of rotation, scientists speculate about their age by analysing the earring layers of the blue whales. Using this method, scientists measure the oldest blue whale with a life expectancy of about 100 years. However, the average life expectancy of blue whales in general is about 80 to 90 years。
10. The future of uncertain stocks
In addition to commercial whaling (e. G. Under the guise of “scientific research” in japan), new threats plague blue whales, such as marine noise pollution, ship strikes, chemical pollution and climate change. The international union for conservation of nature (iucn) has identified blue whales as endangered species。
