Wildlife scientists have observed a long "rope" wandering around behind a bear's anus in Alaska's Katmai National Park. What do people suspect this is? Later, experts verified that this slender "intestine" was called tapeworm and belonged to the intestinal parasite. It is either 1-2 meters long and up to 10 meters long. Tapeworms are said to be present not only in bears, but also in us humans. When I think of this, I don't feel frightened. Why do tapeworms appear in animals?
<h1 class="pgc-h-arrow-right" data-track="25" tapeworm ></h1>
Tapeworms belong to the tapeworm family of the phylum Oblates, which are banded in length, have no mouth or digestive tract, and are essentially hermaphrodites. Tapeworms do not have a digestive tract, and there are many villi on the surface of the body, relying on villi to absorb nutrients from the intestines for their own needs.
The way they live is to live on a host, and in general, some have only one host or two. They rely on suction cup hooks on the head segment to stabilize the host.
Its body is "big", longer than the human body. For example, in alaska, the tapeworm on the outside of the body is about 3-6 meters, but this is not all, it may just be the head and tail of the tapeworm exposed, and the rest is still inside. It hides deep inside the animal's body, some for several years, and is difficult to detect. If one day a person's body has a headache that is unbearable, nausea and want to vomit, it is likely that tapeworms are doing the work.

First of all, let's understand how tapeworms enter the body. As mentioned earlier, tapeworms are parasites whose bodies can be divided into segments, each of which has the ability to reproduce independently. So when tapeworms are swallowed by the host, these eggs also produce new tapeworms. The brown bear is a mammal, and there is a salmon that migrates upwards in the rivers of Alaska, when the clever brown bear will guard the surface of the water and quietly wait for the "unearned" fish delicacy.
Although the delicacies are very happy, after all, the happiness is short-lived, and the pain is coming. Because of the old saying that "disease comes from the mouth", these salmon have a large number of tapeworms in the waters, and when the tapeworms enter the bear's body, they have since settled down. They are very reproducive and it doesn't take long to produce a large number of eggs in the bear's body.
When a bear defecates, the tapeworm's eggs are also excreted. Is this the fate of a tapeworm's life? That's not it, it's just the beginning of new life, because the eggs will return to the river again, and then start the cycle of "regeneration" again.
In this way, the tapeworm parasitic in the bear's body will be dragged by the bear, because the bear's claws are not very flexible, even if the heart wants to tear it off, it is powerless, and the bear has no choice but to rely on the way of rubbing the tree to cut it off.

Tapeworms are most commonly found in the human body as pork tapeworms and beef tapeworms. The intermediate host of Tapeworm pig is pig, and the intermediate host of Tapeworm bovine is cattle. The length of the cattle belt is much longer than that of the pig belt, and some tapeworms can reach a length of up to 25 meters.
Pig belt is tapeworm into the pig stomach, stomach acid and protease and other substances will digest its shell, and then the larva break out of the shell, once settled in the pig body, it will automatically grow into a bag, that is, "rice pork", that is, the "white rice" in the meat. If humans eat these pork raw or eat unspanned pork, it is conceivable that these tapeworms will also naturally enter the human body. Then it began its "demonization".
First, it will embed its head in the wall of the intestine, and then camp here, gradually becoming larger and longer. Tapeworms are cut off and then excreted with feces. If it is accidentally left in the human body, soon your body will have abdominal pain, bloating, loss of appetite and other symptoms. Severe cases also need to be treated surgically.

Weight loss is always a hot topic nowadays, especially for women, and weight loss must not be delayed. The theory of tapeworm diet is also very simple, taking a pill with tapeworm eggs, and then the eggs enter the human body to hatch into tapeworms, tapeworms rely on the body's diet to survive, so that the purpose of weight loss can be achieved. It is said that this method was favored by the Victorians at that time. Even if there are some side effects later, they are still willing to eat.
In fact, about this tapeworm weight loss method, BBC host Michael Mosley has experimented in a documentary, personally experienced the cannibalization of tapeworms, and did not expect that his weight did not drop, but also rose by two pounds. He explained that because of the presence of parasites, they competed with him for food, which made him want to eat some sugars and carbohydrates to supplement his needs. Therefore, this tapeworm weight loss method is not a scientific way, and it is not a matter of failure to lose weight, but it also makes people fatten. Don't take it lightly.

See here, don't be afraid of tapeworms, if it is still more honest in the host body, in fact, the impact on animals is not very large. In addition to the taenia parasite, there are many parasites in the world that have not yet been discovered, so there is no need for us to exterminate them, because they are also part of the life of the earth. But if it is "lively and active", the impact on animals is still more serious.
