The Solomon Islands—a republic comprised of scarcely one thousand islands located northeast of Australia, between Vanuatu and Papua New Guinea—is an considerable dilemma of a globe. Dense, sensuous rainforest blankets a infancy of a islands, and a country’s coral embankment biodiversity is among a richest in a world. Many of a plants and animals in a Solomon Islands have developed in superb isolation, and now, one of these animals has emerged from a halcyon surroundings, divulgence itself to scholarship for a initial time: a vika (Uromys vika), a big-ass rodent four times a distance of even a heftiest of a familiar, city-slicker variety.

What, we were awaiting a beautiful pleasant bird or something?

Described in a newly-published paper in a Journal of Mammalogy by researchers during Chicago’s Field Museum and a Solomon Islands’ Zaira Resource Management Area, a vika is a steer to behold. Including a scaly tail, a low brown, strong rodent can be a feet and a half long, and can import as many as a pineapple. The vika, like a closest relatives, is an zealous traveller and expected spends many of a time high in a trees of a rainforest, clambering around in a center of a night many like a possum. This new class can be renowned from other Uromys species—many of that are also found in a Solomon Islands—by quantifiable differences in skull figure and by a genes. So far, a vika is usually famous from a island it was detected upon, Vangunu.


While Uromys vika is “new” in a formal, scholarly sense, a animal was already a partial of a normal believe of Vangunu’s residents. It was informed to many people on a island as a brawny rodent that favourite to assimilate immature coconuts, tedious into them with a imperishable incisors. Some of a beginning available accounts of a vika from locals embody records that it was presumably common on some of a small, former camp islands only offshore Vangunu. The vika’s introduction to a systematic village came after years of searching, after lead investigate author Tyrone Lavery listened descriptions of a rodent from Vangunu locals behind in 2010. After many time and bid attempting to find a hulk rodent in Vangunu’s rainforest, a singular citation was eventually found scrambling out of a felled tree. The regard and collection of a earthy citation was a final square of a puzzle.

Currently, there is many to learn about a vika and a lifestyle. For example, it hasn’t been reliable around observations if a animal mows down on coconuts. However, on Vangunu, a nuts of a Canarium tree—galip nuts—have been found with turn holes chewed into them and a interior beef removed. Given a specific form of teeth outlines on these bulb holes, it’s suspicion that a newly-discovered hulk rats are a culprits. If vika can cavalcade by a thick walls of a galip nut, it’s not laboured to consider that coconuts might indeed be on a menu as well.

The vika is a initial rodent detected in a Solomon Islands in 80 years, and fits into a conspicuous pantheon of Solomon Island mammals, half of that are found nowhere else on Earth. Some of these embody a dwarf drifting fox (the smallest fruit bat in a world) and a Guadalcanal monkey-faced bat. This hotbed of mammalian endemism is mostly due to a islands’ position between landmasses: tighten adequate for things to fly or boyant there occasionally, though distant adequate divided to make withdrawal a islands difficult. The local land mammals of a Solomon Islands are roughly exclusively bats and rats, both animals that are apparently utterly good during reaching far-flung locations.


“Vika’s ancestors substantially rafted to a island on vegetation, and once they got there, they developed into this splendidly new species, zero like what they came from on a mainland,” explained Lavery in a statement.

Tragically, so shortly after a systematic debut, Lavery and his colleagues design a vika will be immediately designated “critically endangered,” given it is so singular and a little local operation on Vangunu is threatened with logging.
