Hog-nosed rat, a new rat species discovered in Indonesia

Hog Nose rat

A new species of rat has been discovered by the Curator of Mammals while doing a survey of Sulawesi.

Jake Esselstyn, the Curator of Mammals at Louisiana State University has found a new rat in a trap. He found that it was “charismatically different” from other rats. The rat is now called “hog-nosed rat.”

The hog-nosed rat is found in the island of Sulawesi, Indonesia.

Researchers found this fascinating rat in 2013 on Sulawesi.

Esselstyn said that he and his team were not expecting to catch a new species of animal, but when they caught it they knew that it was a new species of rat family.

The discovery of the hog-nosed rat or Hyorhinomys stuempkei is a surprise to the world of animals.

At first, researchers did not take much notice of them because they appear to have the same size like other rodents. It is unknown why this species have evolved as such, but one thing can be estimated that it might have enhanced its sense of smell.

Kevin Rowe, Museum Victoria researcher said, “To Australians, Hyorhinomys is a bit like a rat version of a bandicoot, with long hind limbs, huge ears and a long, pointed face ideal for slurping up invertebrate prey.”

However, the oversized incisors are not loveable. Its teeth do tell that it’s more of a rodent, its size also adds to the fact, but they’re always uncovered and stick out.

The scientific name of the species is Hyorhinomys stuempkei, that aptly describes the species. Hog which means hog, rhino means nose and mys which means rat.

H. stuempkei is missing a key element, specifically the coronoid process. This process allows the rate and humans to easily chew hard foods, such as plants and seeds.

Esselstyn said, “There have been lots of new species of rats being discovered in areas like the Philippines in the last 10 years because biologists are putting an effort into actually surveying them.”
