In marine life, killer whales are both cute and fierce animals, their body color is black and white, but their personality is fierce, good at attacking prey, even great white sharks are their food, but there is another shape in the dolphin family that is very similar to killer whales - pseudo-killer whales. Recently, a group of pseudo-killer whales appeared in a certain area in the northern part of the South China Sea, which is the first time that Chinese researchers have found and recorded this animal group in this area.
Killer whales, people are very familiar, pseudo-killer whales, it sounds strange, in fact, killer whales and pseudo-killer whales belong to the dolphin family, the appearance is also very close to similar, but the body color is completely different, the color of the killer whale body is black and white, the back is pitch black, there is a saddle-shaped gray-white spot behind the fin, there is a fusiform white spot behind both eyes, most of the abdominal surface is snow white color, and the body color of the pseudo-killer whale is black.
In the dolphin family, killer whales are the largest species, adult male killer whales average length of 8 meters, weigh 5.5 tons, female killer whales average length of 7 meters, weigh 3.8 tons, and pseudo-killer whale dolphins account for the third size, about 5 meters long, weigh 1 to 2.2 tons.
On combat effectiveness, killer whales are called ocean overlords, combat effectiveness is far more than pseudo killer whales, but the appearance of pseudo killer whales looks more fierce, they do not have the distinct black and white of killer whales, it is a black body, plus the false killer whale head is round, the mouth is large, the mouth is cut in the direction of the eyes, so that the pseudo killer whale looks more fierce, in fact, they hunt without killer whales, pseudo killer whales mainly feed on cephalopods, and also eat mackerel, bonito, bonito and so on.
Pseudo-killer whale is the only species of pseudo-killer whale in the dolphin family, also known as black catfish, pseudo-killer whale, pseudo-pilot whale, pseudo-orca, etc., their population distribution is relatively wide, in addition to the Arctic Ocean outside the world's major marine temperate and tropical seas, in China is mainly distributed in the Bohai Sea, Yellow Sea, East China Sea, South China Sea and Taiwan waters. This is the first time that a group of pseudo-killer whales has been found in the northern waters of the South China Sea, which is very significant.
The pseudo-killer whale population is greatly threatened by survival, one is the increasingly serious environmental pollution in the sea area, and the other is the large number of human hunting, resulting in the rapid reduction of the resources of the pseudo-killer whale, which makes the pseudo-killer whale population endangered, and has become a protected animal in China, which is a national second-level key protected animal in China.
