In order to find the answer, Dr. Andrea Thorne read a lot of information about sea eels and learned that "the sex of sea eels changes due to the environment. When there is insufficient food, most sea eels will become males, whereas when there is enough food, most of them will become females." It seems that Loch Ness is rich in food resources, which makes most sea eels become females, so all the 10 he catches are female sea eels.
Dr. Thain implanted electronic chips into the abdomen of this 10 moray eel, and then put them back in Loch Ness to track their whereabouts. It wasn't long before Dr. Thain found that nine of the 10 moray eels were swimming towards the sea, and began the last stage of their life-the migration to the sea. Soon, all nine moray eels lost their predation action and desperately swam to Florida across the Atlantic.
After swimming at sea for about 6 months, the moray eels finally reached Bermuda Algae Sea near Florida, where each moray eel laid 7 million-10 million eggs. After spawning 10 days, the tracker shows the discrete action signs of the sea eels. When salvaged, all nine moray eels died of exhaustion due to fatigue.
Soon, under the care of the male moray eels, all the young moray eels hatched, while the male moray eels and the young moray eels were pushed by the vast ocean currents and quickly drifted to the other side of the Atlantic, and the number of male moray eels escorting the young moray eels was also rapidly decreasing, and all of them would die in a few months. And the little moray eel has no shelter, and it has been reduced to half of the beginning. By the time we get to the middle of the Atlantic, there are not many left. In the end, only about a hundred little sea eels came to Loch Ness. After 10 years of growth, they will follow their parents' footsteps and migrate to the other side of the Atlantic to start a new round of reproduction.
Dr. Thain studied the eel that didn't migrate, and found that it hadn't been seen for three years, and the eel had a stronger appetite and a bigger body. Dr. Thain salvaged a moray eel about 13 years old and found that it had grown to 1.5 meters and weighed more than 60 pounds. After replacing the new electronic chip, Dr. Thain examined it and found that the reproductive system of this moray eel was born with defects. It was a barren female moray eel. It can only "camp" in Loch Ness and kill time by hunting all day. Scientists named it "eunuch eel".
The predation ability and food intake of animals are limited. Why does this eel eat more and more, and there seems to be no limit? What makes it have such a strong predation ability? Professor Meta, an American evolutionary biologist, joined the "Loch Ness Project" laboratory and brought the most advanced high-definition underwater camera, which was placed in the places frequented by sea eels.
One day in 2004, an underwater video caught Professor Meta's attention: a giant grouper 50 cm long was bitten by a sea eel with its fangs. The grouper was swallowed by the sea eel as quickly as it was sucked by a vacuum cleaner. The lake hardly fluctuated, and the grouper was already dead. Professor Mehta thinks that the predation process of this moray eel is very unique, which seems to be different from that of ordinary moray eels. Later, I personally went into the water to open and fix the big mouth of the moray eel with a fixer. When I carefully examined its mouth and throat structure, I found that it even had an inner jaw. Whenever I bite food, the inner jaw will pop out in a conditioned way, and the hooked food will be quickly dragged into my stomach. It looks like the prey was sucked in by a vacuum cleaner. Loch Ness moray eel is the only animal that has adopted this special feeding mode so far. And the moray eel in Loch Ness has no natural enemies. As long as its mouth is opened and closed, it can sweep its prey into its mouth like a vacuum cleaner.
On September 23rd, 2004, British mysterious zoologist Richard Freeman joined the Loch Ness Project with the most advanced multi-wave sonar locator and voice-activated camera.
