The killer whale is a kind of whale, and it is one of the more ferocious whale species. They also have many nicknames, such as "killer whale" and so on. Many people may be surprised to learn this nickname, because killer whales generally do not attack humans on their own initiative. Although orcas are carnivores, they do not eat humans. Only when humans kill them, or when humans provoke them, can they attack humans.
In fact, "killer whale" does not mean that killer whales often kill people, but the problem of translation errors. Because the killer whale's English name is "killer whale", which literally means "whale killer". However, in the process of translation, some translators did not translate them literally, but translated them into "killer whales". And because the killer whale itself is a very fierce creature, this nickname has become more popular, and few people will question this translation.
In addition to the nickname "killer whale", orcas have other nicknames, such as "killer whale". This nickname is not related to the killer whale's personality like the previous nickname, but to the shape of the killer whale's body. The dorsal fin of killer whales is very high, especially male killer whales. When they float to the surface to breathe or do other activities, their dorsal fins will come out of the water, which looks like an ancient Chinese weapon called "halberd", but it is not a standing halberd, but a halberd inserted into the water upside down, so it has this nickname.
