It is like dinosaurs that about 2,000 years ago world’s largest rat had wondered on the Earth. Scientists were found the skeleton of the monstrous rat during cave excavations in East Timor. According to the Archaeologists, it is believed to have an expected body weight of about six kg.There they found other rodents, the group of animals includes rats, which grow to a bigger size. The largest rodent of all is the capybara that lives in or near freshwater in South America. It can grow up to 130cm long and weigh up to 65kg. The Philippines is also home place to a few species of cloud rat, which can weigh over 2kg. However, of the exact rats that include urban brown and black rats that belong to the genusRattus. These kinds of rats have few similar with the new species. Conservation International was made an expedition to New Guinea In 2007.There they discovered another closely related giant woolly rat, which can weigh up to 1.4kg. Woolly rat also belongs within the genusMallomys. This species of rats live in the Foja Mountains, which is a part of the Mamberamo Basin. CISCO –Australia’s national body for scientific research team also found 13 other species of rats. Although among them 11 are new to science, of which eight of the rats are estimated to have weighed more than 1 kg. The scientist thinks the monster rat survived up until about 1,000 to 2,000 years ago. Today’s heftiest rats live in rain forests in the Philippines and New Guinea, which weigh around 2 kg.
The world’s biggest rat is the Bosavi Woolly rat. It can be found in an Island that includes Papua New Guinea. However, this place is famous for the number and variety of the rats and mice that live there. The larger rats are regularly caught by hunters and eaten. But fortunately Scientists has discovered a new species of giant rat in a remote rainforest in the Mount Bosavi regions of the Papua New Guinea. This rat is an exact rat just like the same kind of rats and mice you find in houses and city sewers. This world’s biggest rat can grow from nose to tail 32.2 inch or 82 centimeters (3 feet) and it can weight up to 3.3 pounds (1.5 kg). Bosavi Woolly rat can live up to 5 years. Woolly rat is as big as a fully-grown house cat. This species is thought to be one of the largest rats ever to be found.
A British scientific team was discovered a hole formed by the extinct volcano, Mount Bosavi. There they found a giant rat. At first, the giant rat was first captured on film by an infrared camera trap. A wildlife photographer Gordon Buchanan set up the camera in the forest on the slopes of the volcano to take photo of it. Then trackers helped the team managed to catch a live sample and the trapped rat measured long at 82cm. It had a silver-brown coat of thick long fur. According to the scientists who examined it, considers that it may help to survive in the wet and cold conditions for the high volcano crater. The location where the rat was discovered lies at an elevation of over 1,000m. Later investigators say the rat belongs to the genus Mallomys, which holds a handful of other out-sized species. Occasionally, It has been called the Bosavi woolly rat, whereas its scientific name has yet to be agreed.
