This is one of the biggest rats in the world. The subalpine woolly rat, which wasn’t described until 1989, is an incredibly elusive species — known for climbing trees at night and hiding in underground burrows and tree canopies during the day in the steep highlands of New Guinea’s rainforest. But now, the rodents — also known for their sharp teeth, thick fur, 3-inch-long paws and for growing to be almost 3 feet and more than 4 pounds — have been captured on film for the first time.
