Volume 2: Chapter 51 - The Dolphin with a Name

For a long time, we thought that humans were the only species that could call each other by their names, but this was not the case. Pen | fun | pavilion www. biquge。 info New research has confirmed that wild bottlenose dolphins will also make between them

With the name, what an amazing find!

The use of names now seems to be a matter of course, but in reality, the process of creating and using names is very complex. In the eyes of scientists, names are sounds that we can remember

Identifiers, which are used to represent specific objects. Both domesticated parrots and dolphins are able to memorize and use sound signs, and researchers believe they must have existed in the natural environment. Marine life of the world

Scientist Mary and her assistant Mike have discovered that dolphins can use similar names to call each other.

-- Researchers recorded a special set of sound combinations from groups of wild dolphins. One of the most critical sounds made by dolphins is the "signed" call.

The sound is marked with its own unique characteristics, so that each dolphin's call is different, and the analysis of the recordings of wild dolphins has revealed that these different individuals have different signatures from each other

Calls account for two-thirds of all sounds made by dolphins.

While surveying the Devil's Triangle at the bottom of the Atlantic Ocean, Mary and her boyfriend Mike were the first to discover the dolphins' unique chirp signals. However, the dolphin actually makes the name of the signature

We know very little about it so far. Bottlenose dolphins have developed their own signature names by the time they are a few months old. This cry is likely to be based on the mother's chirping, and has been used for decades

None of them change, but males sometimes mimic the chirpings of new partners in the group.

Dolphins produce different sounds by changing the frequency of infrasound waves, and even their own kind thousands of nautical miles away can receive this sound wave in the depths of the sea. This is related to the production of radio FM signals

The principles are very similar. Previous research has suggested that dolphins, like humans, need to learn to make sounds. Normally, they reassemble and merge with the calls of other dolphins

Their own unique voice.

The uniqueness of the signature name allows it to be used by dolphins to identify each other, but this idea has not been scientifically proven.

To understand the role of the signature vocal signals, scientists need to study free-swimming dolphins. This is quite difficult in practice. According to the previous research methodology, it is necessary to first

Wild dolphins are captured, their signatures are recorded, signatures are recognized, and then they are released, but how can they be released underwater from a fast-swimming group of dolphins?

What about these special signatures in the noisy sound waves?

After analyzing the observational records, scientists found a way to do it. They found that the dolphins' signatures had a special rhythm, and that the two adjacent signatures always had 1-

10 seconds of overlap, that is, within 1-10 seconds of the previous signature sound, the next signature will be sounded. With this feature, it is possible to send the signature sound signal from a group of fast-swimming dolphins

The sound is distinguished.

-- In the Devil's Triangle of the Atlantic, Mary and Mike recorded the signatures of 18 dolphins. They broadcast the recorded cries to the individual who sent them, and record the lure

reactions; The reactions of other dolphins in the same group and dolphins in other groups to the play of the byline were also recorded. Twelve of the 18 dolphins made it when they heard their signatures

Only 2 responded to the calls of other dolphins in the same group, while the unfamiliar dolphins did not respond to the signatures.

Scientists believe that the above response may be the dolphin's response to hearing their close companions call their names. Mary and Mike claim that there are other dolphins in the same group who hear familiar signatures

The likelihood of a corresponding response to the name.

All of these findings suggest that each dolphin may use a specific call to connect with a specific companion. From this point of view, the role of the byline is very similar to that of human names, however, in

Naturally, there are very few cases of dolphins mixing their signatures. From this point of view, dolphins' names are mainly used to identify themselves, rather than being used by their companions.

It can be seen that in the depths of the blue ocean, there must be many mysteries unknown to us humans waiting to be solved, and we can be sure that the sea creatures that know their names

Dolphins are definitely not the only ones。。。。。。 Therefore, it seems not surprising that sometimes we humans like Mary and Mike are unfortunately shipwrecked in a certain sea area and often encounter dolphins to rescue them?!
