RODENTS do get some bad press but a newly discovered species of rat may turn things around.

The new rat has been awarded a place in the 2017 top 10 list of previously unknown species.

Experts estimate that less than a quarter of Earth’s flora* and fauna* species have been identified and this discovery was made from the work of local and international scientists.

The omnivorous* Slender Rat was discovered on Sulawesi Island in Indonesia by Museums Victoria mammalogist Dr Kevin Rowe and his US and Indonesian team, helped by local Rantepangko villagers.

Selected from 18,000 species of animals and plants discovered across the world in the past 12 months, the Slender Rat was included on the College of Environmental Science and Forestry’s Top 10 New Species for 2017 “not so much for its rattiness but for the evolutionary story it tells and the conservation message,” Dr Rowe said.

The pristine* rainforest and isolation of mountainous Sulawesi, north of Australia, has proven a treasure trove for researchers discovering new species.

Together with the indigenous peoples’ tradition of not farming or clearing land beyond a certain point at Mount Gandangdewata (which means God’s gongs, because of the unique noises coming from the peak), 24 different rats, including four new species, have been identified by Dr Rowe’s team.

Although the slender rat’s closest relative is a water rat, anatomically* they are starkly different, one evolved for swimming and one for life on land.

Examples of the slender rat, aka Gracilimus radix, are on display at Museums Victoria until July 6.

“We hope that the recognition of the slender rat and our other discoveries on Sulawesi bring

greater attention to Sulawesi’s amazing but threatened forests, which are home to many

thousands of species found nowhere else,” Dr Rowe said.

While thousands of new creatures are discovered each year, thousands of others are becoming extinct.
