The blue whale is the largest animal on Earth, the adult blue whale can be more than 30 meters long, weigh more than 100 tons, equivalent to the weight of 20 elephants, the largest can even exceed 150 tons, it is also considered by biologists to be probably the largest creature ever appeared on the earth, larger than all dinosaurs.
However, although the blue whale is huge, its favorite food is very small, only 1 to 3 cm long krill and other small fish and shrimp, but the killer whale is different, it is the largest hunting beast on the earth, the average weight is about 6 tons, larger than the elephant, the largest can be more than 8 degrees, of course, its size can not be compared with the blue whale, but its diet on the prey is also very large, including great white sharks, whale sharks, fin whales, humpback whales, etc., and even blue whales.
According to Australian media reports reprinted by China's media, on March 18, on Bremer Bay on the west coast of Australia, a group of whale watching tourists witnessed a group of killer whales hunting blue whales, and the video data taken by tourists showed that a blue whale mistakenly entered the area, was rounded up and attacked by as many as 75 killer whales, and finally hunted and killed because of defeat, becoming the food of killer whales.
Blue whales are much larger than killer whales, how do killer whales hunt this behemoth? From its hunting operations, we can see the wisdom of the mammal, which is considered to be the territory of the killer whale, a rash blue whale mistakenly entered this place, so a group of killer whales adopted a collective attack, they pressed on the blue whale, so that the blue whale could not float and breathe, after about 2 to 3 hours of fighting, finally caused the blue whale to suffocate and die.
This blue whale is not very large, with a body length of 15 meters, it is likely to be a blue whale that has not grown up, and its weight is about 20 to 40 tons, but even so, it is more than a single killer whale.
The same thing happened on March 21, 2019, also on the west coast of Australia, when 6 killer whales joined forces to kill an 18-meter-long blue whale, which shows that it does not take too many killer whales to hunt the blue whales, and after the blue whales were hunted, 50 killer whales came to eat the meat of the blue whales, and some birds and fish participated in the sharing.
Killer whales are known as "tigers in the sea", there is no opponent in the world's oceans, even the largest and most ferocious great white shark in the fish (body length 3 to 6.5 meters, weight 1 to 3.5 tons), encounter killer whales are often hunted fate, killer whales in the marine biological chain is basically equivalent to the tiger's position in the terrestrial biological chain.
Although it has been so overbearing, but the killer whale is still a very social social animal, often a large group of people acting together, which is equivalent to a group of masters who are already invincible, any one of them can cross the rivers and lakes, but they have formed an alliance, who else can deal with this?
Killer whale hunting blue whale scene, it is easy to make people think of the lion group hunting elephant scene, elephants are much larger than lions, but want to hunt elephants lions will attack the elephant group, the way to use is to choose an elephant to attack, constantly drive it, such hunting operations will usually be carried out at night, because the elephant's vision is not very good, there may be scurrying around, so that other elephants can not come to help, so the lion will let the driven elephants keep running, such as the elephant is tired and breathless, Multiple lions will jump on the elephant's back, crush it to the ground, and then a group of lions will bite at the elephant and kill the elephant.
The predators of the animal kingdom have also enriched their wisdom of hunting and anti-hunting, interpreting the cruelty and progress of life evolution, and the stories of killer whales and blue whales, lions and elephants will continue to be staged, which may be the arrangement of life on earth in the overall biological chain.
