The mystery of dolphin navigation

It was a strange experience for a captain.

One day in 1871, his ship, the Brinell, sailed not far from Wellington, the capital of New Zealand, and was about to sail in the borros Strait. They told the captain that the rocks were like forest, the waves were rough, and the fog was thick. It was very difficult for the ship to move. If it was not done well, it would destroy people. The captain paid special attention to the sailors and strengthened the lookout. Never make mistakes.

Under the command of the captain, the “brinier” sailed in the narrow channel, and the crew members guarded their posts one by one and dared not be a little careless. The watchers kept their eyes on the sea, and the ship was sailing hard in the wind, waves and torrents. Suddenly, a crew member in charge of the lookout shouted, “Captain, there are rocks ahead!”

It doesn’t matter. The whole ship is frightened. People are afraid, but don’t hit the stone!

The Captain stood calmly in the cab, watched the target carefully with a telescope, and said confidently, “don’t be nervous, it’s not looking at the stone. Look carefully. It’s moving. There’s no rock that can move. ”

A sailor took the captain’s telescope and observed for a while. He said, “yes, that rock can move!

”I think it could be a whale swimming. “The captain added.

When the captain said that, a false alarm was counted.

”The Brinell is getting closer and closer to that black spot. You can see clearly that it is a big dolphin.

Strangely enough, the dolphin did not swim when she saw the ship coming, but sailed with it. In a short time, she swam to the front again, keeping a distance from the Brinell, but refused to leave.

”This dolphin is so interesting! “Said the captain to himself.

”Mr. captain, it seems to me that it is piloting us. “Said the steersman, who was steering.

”The captain also seems to have found something.

”There must be no reefs where dolphins can pass. Let’s go with them first. “Under the command of the captain, the ship followed the dolphin closely.

The dolphins swam forward on the fast channel, flexibly avoiding one reef after another and dangerous shoals, and led the “brilnier” out of the channel safely.

After arriving at the destination, the incident was spread by the sailors.

Later ships encountered the same thing, as long as they followed the dolphin, they could sail through the channel smoothly. In order to express their gratitude to the dolphin, the sailors named it “burrops Jack” after the channel. Later it was simply called “Jack”.

Jack volunteered to lead the ship, leading one ship after another across the dangerous channel, and worked diligently for 22 years. I didn’t expect to be killed in 1892.

On that day, a ship called “Penguin” passed through the channel. A drunk on board fired several shots at Jack. After the sound of the gun, Jack disappeared. The whole ship was so popular that the drunk was beaten up.

Where did Jack, the lovely dolphin, go? Was he frightened and hid? Was he injured and left his hometown? Or was he shot dead and buried at the bottom of the sea. People are sad to lose Jack.

I didn’t expect Jack to show up again half a month later. As usual, continue to lead the ships across the channel. But it has a very good memory. As soon as it sees the penguin coming, it’s far away. The sailors of the penguin also went to work on other ships. Later, the ship, without Jack’s guidance, finally hit the rocks and sank. But many other ships, with Jack’s help, came and went safely in the channel.

In order to protect the dolphin, the governor of New Zealand issued a special order on September 26, 1904, forbidding to hurt the dolphin escorting the ship in the channel, and the violator was fined.

After 41 years of hard work for people, Jack disappeared one day in April 1912. Never saw it again, it disappeared forever.

A monument has been built in Wellington, the capital of New Zealand, to commemorate the dolphin for the benefit of mankind.

Why did Jack dolphin lead the ship? To understand the mystery, some experts consulted the literature and newspapers at that time, inquired about the sailors at that time, and learned that Jack dolphin often wiped the ship’s side with his body and rubbed against the bottom of the ship when he was traveling with the ship, which was the reason why he was close to the ship.

Some scholars also speculate that dolphins are interested in ships because they can rub their bodies against the smooth hull, or like to play in the waves and currents aroused by the ships, which will make their skin feel comfortable.

But is this really the case? How can dolphins explain how to navigate in front of the ship? So, this is still a mystery that has not been completely solved.
