Ilin Island cloudrunner

The Ilin Island cloudrunner (Crateromys paulus) is a cloud rat known from a single specimen purchased on Ilin Island in the Philippines, where the Taubuwid Mangyan call it siyang. The Wikipedia article that serves as this entry's source describes it as a fluffy-coated, bushy-tailed rat that may have emerged from tree hollows at night to feed on fruits and leaves. The specimen was collected on 4 April 1953 and given to the National Museum of Natural History in Washington. Because there is no proof that it came from Ilin Island, searches now focus on nearby Mindoro. The species is on Re:wild's list of the 25 most wanted lost species, and the IUCN lists it as data deficient.
