Do Dolphins Have Names?
Scientists have found that dolphins call each other by "names". These names are actually special whistles (哨声). Each dolphin creates its own unique whistle when it is young. This whistle acts like a name tag.
In the past, scientists thought dolphins just made random noises. However, new studies show that dolphins use these specific whistles to get each other's attention. For example, if a dolphin wants to play with a friend, it will copy the friend's signature whistle.
Researchers recorded dolphin whistles in the wild. They played the recordings back to the dolphins. When a dolphin heard its own "name" whistle, it responded immediately by swimming towards the speaker or whistling back. But when it heard the whistles of strangers, it usually ignored them.
This discovery proves that dolphins have a complex social communication system. They can remember the "names" of their relatives and friends for decades. This is quite similar to how humans recognize each other by names.
Moreover, dolphins can remember the whistles of other dolphins even after being separated for more than 20 years. This shows that their long-term memory is very powerful. Scientists believe that this ability helps them maintain strong social bonds in the ocean.
