A Mysterious Rat Vanished Into the Mountains in 1989. It Just Showed Its Face for the First Time Since.

Here’s what you’ll learn when you read this story.

• Mallomys istapantap It is the largest (and also least studied) woolly mouse species in New Guinea and was eventually documented with photos and videos.

• The species was first documented in 1989, but in their attempts to study the creature further, researchers have found little beyond a handful of museum specimens.

• Information protected by local Indigenous people M. istapantap Studies by scientists (not the species itself) are rare.

Not all rats are sewer or subway dwellers running away with (and then) someone’s slice of pizza. it goes viral For this). In the remote mountain rainforests of Papua New Guinea, there is a creature that has managed to evade humans for decades; a giant mouse hiding in the leafy shadows and never recognizing a discarded pizza crust.

To meet Mallomys istapantap, Subalpine Woolly Mouse of New Guinea. This giant rodent can easily grow to the size of a house cat and reach a length of 85 centimeters (or 33 inches). Several different species of woolly mice have been found in the area, but M. istapantap It is easily the largest and least researched. It is also one of the largest rodents in the world, along with the following species. pacarenas And capybaras.

Zoologist František Vejmělka was the first to document this mysterious nocturnal rodent in the wild, capturing the creature with both photos and video as it scampered down a tree branch just after sunset.

“The rarity and limited information about the ecology of the Subalpine Woolly Mouse in museum collections does not reflect its actual rarity in nature, but rather appears to be linked only to the remoteness of the habitats it occupies and the fact that it cannot be recorded by standard small rodent trapping methods,” Vejmělka said in a study recently published in the journal. Mammal.

Isolated island habitats provide some exotic and unusual fauna. In addition to giant shrews, New Guinea is also home to birds of paradise, iridescent snakes, fanged frogs, growling fish, tree kangaroos and several rare species. echidna These are not found anywhere else on Earth. Mallomys It is a genus endemic to the island and consists of four species of woolly mice. Documentation for other types is slightly better, but M. istapantap it was first announced It was made in 1989 and was only documented visually with an illustration in 1995. Until now, the only way to examine it up close was to examine a handful of museum examples.

M. istapantap It is a herbivore that eats mostly ferns and lives in nearby mossy forests or meadows. mountains. Mostly terrestrial but can still climb trees If he needs to escape from predators, his thick, shaggy fur protects him from the cold of high altitudes. The species name “istapantap” is Melanesian Pidgin (spoken by local indigenous people) and means “living above” or “being at the top”. This knowledge of the creature’s existence indicates that it was likely seen regularly among the roots and leaves by local people. The hunters who helped Vejmělka collect samples appeared to know the areas he was most likely to find M. istapantap, population numbers are still unknown.

In addition to guidance from local hunters, Vejmělka set a camera trap on a fallen log over a stream in a dense forest on Mount Wilhelm, New Guinea’s highest mountain. The camera worked for eight nights until a man arrived. M. istapantap, eyes shining inside darknessHe was filmed crawling along the log.

Woolly rat species living at lower altitudes have longer tails, while those living at higher altitudes have shorter tails; This axiom also applies to the white-tipped tail of mice. M. istapantap. They have dark, brownish-grayish fur with white underparts and pale feet, and females are slightly larger than males. Vejmělka also discovered a color change never before seen in this species (or any other rodent species in the region). hydromini (rodent group for that matter) has a yellow line on the chest which he thinks is either genetic or staining from the sebaceous glands. (This may be related to territorial behavior.)

“The results presented here first demonstrate the importance of conducting field trips today, especially to understudied regions of the Earth.” in question Vejmělka. “Combination of modern and traditional detection methods […] “It resulted in the first specimen records of this remarkable rodent in over 30 years.”
