1001 wondering: How much does the world's largest mouse weigh?

Capybara water guinea pigs are the largest rodents in the world. As noted, there has been an individual weighing nearly 100kg in Brazil.

Giant mouse or giant mouse is the term for the mouse is very large size compared to the same type and this term is applied to many different rodents. They tend to be native to the tropics and subtropics.

Some have thrived in other climates, including Coypu and Gambia kangaroos, which have become invasive, even present in urban areas. Giant mice have also been depicted in popular fiction, where they are often depicted as monster-like creatures.

Large mice are often referred to in the UK as "Giant rats" or "super mice", which are often domesticated mice (rats, brown rats, black mice, and mice) due to mutations or for various reasons, such as nutrition, have become enormous and appear to be increasing. The term "giant" here does not mean that the mice are too large to be imagined, but that they become immune to the toxins used by rat experts.

The emergence of a giant mouse species is a natural process, which is reflected in evolution. When dinosaurs were alive, there were mammals in the world, but they were very small, and by the time the dinosaurs disappeared, the earth began to appear to be as big as a cow now extinct. The worst nightmare is probably every few months to see scary photos of oversized mice posted in the newspaper.

Heavy as a pig

Capybara water guinea pigs are the largest rodents in the world. As noted, there has been an individual weighing up to 91 kg in Brazil. Any discussion of unusual sized rodents will have to refer to the name of the giant South American water guinea pig (capybara), but they are actually more closely related to guinea pigs. is a normal mouse (Muridae family, also known as Old World mouse).

Capybara guinea pigs (Hydrochoerus hydrochaeris) are widely available in South America. They often live around lakes, swimming and snorkeling when seeking ways to escape from land predators. The ancestor of water guinea pigs originated in Africa about 80 million years ago and arrived in South America 40 million years later. The hamster's body is 1.35m long, 60cm high and the weight can exceed 60kg.

Large Sumatra bamboo mouse (Rhizomys sumatrensis) can be up to 50 cm long, from the tip of the nose to the end of the tail. This length is similar to brown mouse, but the big Sumatra bamboo mouse's tail is only about 12 cm long. So this large bamboo mouse can weigh as much as 4 kg, almost the size of a cat

Giant mountain mouse Sunda (Sundamys infraluteus) : This mouse species is large, omnivorous and lives in mountainous areas. Sundamys infraluteus can reach 60 cm in length, but rarely weighs more than half a pound, because its body shape is slightly different

Gambia kangaroos : One of the longest in the Old World kangaroo is the Gambian kangaroo, which can grow up to 90 cm from tip to tip, weighing up to 1.4 kg to 4 kg. The large size makes it a favorite pet, three times heavier than a traditional guinea pig, which is domesticated brown mouse.

In addition to the legends of this giant kangaroo, the Gambian kangaroos escape from a private collection that worries people in Florida Keys. The species was declared an invasive and thought to be associated with the smallpox epidemic in the United States in 2003. However, this kangaroo has a lot of love in its home country of Africa. Gambia kangaroos have a very sensitive sense of smell, often trained to detect mines and UXO, and many Americans also raise them as pets.

Northern Luzon (Phloeomys pallidus) : These are mouse species that are larger than Gambian kangaroos, we must go to Asia, especially on islands with unique ecosystems abnormal growth in size. In the Philippines there is a giant species of cloud mouse that lives on trees. In this species, the giant rattan mouse North Luzon is the largest species, can be up to 75 cm long, weighing up to 2.6 kg.

The giant Mallomys mouse in New Guinea called Bosavi wool mouse is similar in size. The mouse was found on a half mountain that turned off in 2009, and can grow to 82 cm long and weigh 1.5 kg. Since the discovery of this giant wool mouse, the largest species is probably Mallomys gunung, living at extremely high places on the western peaks of New Guinea, weighing up to 2 kg or even heavier.

Giant East Timorian Mice: Large German dog- sized rats were recorded with two fossilized bone fragments of rats. Giant mice found on East Timor Island, Indonesia, are about the size of a dog. But these are not living rodents but fossils because they are extinct.

Identify seven giant mouse species that have gone extinct. The smallest one weighs about 1.5 kg, the largest one is about 5 kg, about the size of a miniature German dog. The ancient inhabitants ate rats meat, because their bones were burned and chewed, rats lived next to humans 40,000 years ago, even though humans were hunted. The extinction of these rats with the arrival of the Bronze Age, the forests, where they lived, were destroyed by humans at that time.

Giant mice appear: due to food or climate change, radiation?

Many people believe that the cause of the mutant mice in urban areas is because of climate change, or people have released some chemicals to the ground, causing the mice to mutate, just enough time and Under favorable conditions, rats will be at least the size of a water guinea pig (Capybara), the world's largest rat. The main reason for the large size of the mice is due to the increasing amount of food left on the street, these mice are large because they are eating too much protein, fat from food sources that people dump in trash, not radioactive as rumored.

Giant mice on a high-protein diet ranged from dog feces to poison pills used to kill rats, but it was no longer effective because the mice became resistant. The reason for the resistance is that the diet consists of trash foods like corn, which contains vitamin K, an antidote to many pesticides. In addition, due to warmer weather conditions made the mouse eat more and the combined factors have caused an alarming danger, in which mice are growing both in number and size. They are like us humans, the more they eat, the bigger.

Besides, mice are extremely good adaptable species. Humans have moved rats around the world, and wherever they live, they grow very quickly, and humans inadvertently remove many native creatures from places where humans appear. This makes the mouse unleashed without a rival and capable of evolving stronger in the future if given enough time. If you list the most disgusting animals, rats probably always break all records, especially the giant mice. Mice are often known as vectors of transmission. They move in herds in the dark alleyways of the city.

Why don't water guinea pigs get cancer?

In the new study, the scientists found that guinea pigs also have a special method of preventing cancer. The genes that determine the function of the immune system in guinea pigs allow for better detection and destruction of dividing cells too quickly. Thanks to this, immune cells in water guinea pigs can inhibit the newly formed tumor. According to the authors of the study, this was not observed in other animals.
