Diving is a dangerous but relaxing underwater sport. When diving, you can see many unknown scenes on the seabed, but these unknowns also have certain risks. There are many kinds of marine life, but also some dangers, such as humpback whales. Humpback whales, as one of the largest animals in the world, are usually very docile. Their staple food is small crustaceans and small fish that swim in groups, and generally do not take the initiative to attack humans. But this does not mean that when diving, divers will not be swallowed by mistake when they meet humpback whales. This happened to a British diver. He was swallowed by humpback whales in the deep water of 14 meters, but fortunately he finally escaped. This diver is an experienced commercial diver. He catches lobsters for a living. He was accidentally swallowed by a humpback whale while diving in the coastal town of provine, Massachusetts. He went to packard and recalled that he didn't see whales at that time, but he felt a huge bulge and suddenly it became dark around him. Then he realized that he might have been swallowed by the fish. At that time, he was worried that there was no way to live. At first, I thought it was swallowed by a huge shark, but when I found that this creature had no teeth, I realized that it was a bigger creature, namely a whale. But great fear surrounded him, and he also experienced a fierce struggle in the whale's mouth. He lost his respirator and was forced to grope in the dark. He couldn't save himself, but fortunately, the humpback whale opened its jaw and the lucky diver was thrown back into the sea. His lobster colleague who dived and fished with him also said that he miraculously survived when he saw the whale surface and vomited Packard. In fact, this magical event in deep water is not uncommon. There are also many things that whales swallow but spit out. According to experts, whales don't eat large prey. If swallowed by mistake, they will feel the presence of foreign bodies. When they find this foreign body, whales will spit out hard objects immediately. This reaction is related to the digestive system of whales. Too big prey is bad for their digestion, because they can't chew without teeth. Therefore, when humans are swallowed by whales by mistake, whales will spit it out immediately when they feel it, but friends who dive should try not to get close to these behemoths and keep their distance to avoid being swallowed by mistake.
