Are killer whales the fiercest marine animals in the world?

Black whales are the most ferocious marine animals in the world. Its body length can reach 9 meters, and there is a huge triangular dorsal fin in the center of its back, which is 30 ~ 40 cm high. It acts as a rudder and can also be used as a weapon when attacking. It has 10 ~ 13 large and powerful teeth on both sides of its upper and lower jaws, which is a powerful weapon to kill other animals. Black whales are gregarious marine animals, and often hunt in small groups of three or four or in large groups of thirty or forty.

According to the April issue of National Geographic magazine 1979, scientists found a group of about 30 killer whales in Baja California, Mexico, hunting a juvenile blue whale about 18 meters long. The scene is very much like a wolf hunting deer on land: "You bite, he bites", and pieces of whale meat and blubber are torn off from this blue whale and eaten collectively. This extremely rare shot was recorded by the photographer.

This group of killer whales seems to have a division of labor when attacking blue whales. Some killer whales are on its sides, as if to control it; Two heads are in front and two heads are behind to prevent it from escaping; Others seem to force it to sink into the water and not let it leave the water to breathe; Others watched its abdomen to prevent it from diving away. The siege began at 1 in the afternoon and lasted for five hours. The front line is 20 nautical miles long, with rivers of blood. By 6 o'clock in the afternoon, the blue whale was black and blue, dripping with blood, and it seems that it will not live long.

Black whales in the ocean not only prey on blue whales, but also prey on other marine animals, large fish and penguins. According to records, a 6.4m killer whale has 13 dolphins and 14 seals in its stomach. Such a ferocious sea beast, no wonder people call it "the overlord of the sea".

But after domestication, killer whales will become gentle and smart, make all kinds of wonderful performances and become friends of human beings.
