    Shane Gero, a scientist at Aarhus University in Denmark, spent 6 years studying sperm whales (抹香鲸), which communicate through very loud clicks. He found that sperm whales in the Caribbean Sea had different clicks from those in the Pacific Ocean. He even “translated” the clicks from a group of Caribbean sperm whales, believing them to say, “I’m from the Caribbean, are you?”, reported National Geographic. As well as being used for communication, the clicks also allow whales to develop a relationship with one another, according to Gero.

Apart from sperm whales, other animals like wolves and apes also have different regional accents. Researchers analyzed the howls of different species of wolves. They found that red wolves, Arctic wolves and other wolves have howls that vary in pitch (音调). In other words, they have their own dialects.

According to Darcy Kelley from Columbia University, most animals learn their accents naturally. For example, macaques (猕猴) start speaking their dialect as soon as they are born. Scientists placed some macaques in a new environment where their playmates all spoke a different dialect. But the macaques still spoke their own dialect. Their environment had no influence on their communication, according to the Washington Post.

“In most species, communication appears to have a genetic basis,” Kelley explained in the Washington Post. “However, among a small number of species, animals can learn from others and develop their own accents.”

Fruit flies are a good example. According to Science Daily, they send messages through their wing movements. Scientists found that fruit flies can only communicate efficiently with others of the same species. However, they can learn new dialects by spending time around other species.

“A proper accent is vital to mating and warning the coming of enemies, which is the basis of protecting themselves,” Kelley told the Washington Post. A species can’t risk changing their own dialect and learning a new one.
