The idiom "The ant nest breaks the embankment" means that a small ant nest can cause the embankment to burst. It tells people that seemingly inconspicuous things often lead to big mistakes, so you need to pay attention to small things to avoid big troubles. ;For example, did you know that a small seagull can also cause fatal damage to a giant whale?

In the shallow waters of the Beihai Sea in Guangxi, a tourist photographed: a giant whale surfaced, opened its mouth, and swallowed a lot of fish in an instant. But at this time, groups of seagulls appeared. Flying over, seabirds all over the sky surrounded the giant whale, seeming to be competing with the whale for food. The scene was very spectacular.

According to reports: As the weather warms up, many different species Fish have begun to gather in the North Sea, which will also attract their predators. This giant whale belongs to Bryde's whale, which mainly moves in tropical and temperate waters. It can reach a body size of 12 meters and feeds on various fish. , including sardines, eels, herrings and mackerels, etc. Therefore, when a school of fish is attacked by a giant whale, it will jump out of the water in panic and try to escape, which will attract seagulls to take a share of the pie.

Bryde's whales are generally difficult to find because this whale does not like to float on the water frequently. However, Bryde's whale calves emerge from the water from time to time. They do not like to gather in large groups and are usually alone. They may move in groups of 2 to 3. The largest group ever found was composed of 12 Bryde's whales.

Bryde's whales have been seen swallowing and vomiting people

In marine life, whales have many differences and can be divided into toothed whales and baleen whales. For example, killer whales and humpback whales are completely different. Killer whales belong to the family Delphinidae, while humpback whales belong to the family baleen whales. Killer whales will naturally prey on prey such as seagulls. Will the baleen whales we are talking about this time prey on seagulls?

For the huge baleen whales, their mouths can indeed hold multiple people, but most whales do not have teeth that can crush bones, and they also feed on tiny organisms such as krill and zooplankton. When a giant whale hunts, it swallows its prey, including a large amount of seawater, and then spits out the seawater through filtering, and the prey is blocked.

The esophagus of baleen whales will not swallow large creatures. The most important thing is that the esophagus of baleen whales is not particularly large. It is only a few centimeters or more than 10 centimeters wide. For example, the diameter of the esophagus of humpback whales is very small. They can only feed on small creatures less than 1 centimeter in length; blue whales are relatively large, only about 30 centimeters in diameter, and are difficult to swallow humans. They will also generally eat creatures that cannot pass through the throat of baleen whales. spit it out.

In February 2019, a Packard photographer in South Africa was mistakenly swallowed by a Bryde's whale thinking it was food while taking pictures of sardine balls, and he was swallowed whole. However, he also He was swallowed for only a few seconds before the Bryde's whale spit him out. It is also enough to make them feel scared. Although they know that baleen whales will not swallow people, they are afraid of being pulled into the deep sea.

Baleen whales will not swallow large creatures, but Toothed whales are the opposite. Sperm whales and killer whales are all toothed whales. Sperm whales have a large esophagus that can swallow large mammals. A 12-meter-long king squid weighing 200 kilograms was once found in the stomach of a sperm whale. However, sperm whales often Activities in the deep sea rarely encounter people.

Do you know that seagulls harm giant whales?

Seagulls are beautiful and ferocious seabirds, especially large seagulls such as skuas. They are very aggressive. When they are hungry and cannot find food, they even dare to attack giant whales and kill them. The skin etc. feed.

There are statistics: In the ocean, it is easy to find wounds on the backs of whales. Through trace comparison, most of these wounds are caused by seagulls pecking, and nearly 90% of whales have different backs. degree of wound.

We all know that complete skin is a protective system. If the whale's skin is damaged and it dives into the ocean, the wound cannot be stopped in time to stop the bleeding, which will cause the whale's body temperature to be abnormal. In addition, if the wound continues to bleed, the whale will eventually be pecked by seagulls and die.

Of course, it is not true that seagulls can injure and kill whales every time they peck. Such cases are relatively rare, so seagulls are not considered whales.The natural enemy of fish, what really scares whales is poachers. Especially the whaling industry of a few countries such as Japan, which operates under the banner of "scientific whaling", has caused many whales to be on the verge of extinction due to excessive hunting and killing.
