You will probably never see him again. But his sad fate may be a lesson for us all.
In a new report, published by the University of Queensland, researchers say the rat is officially history - the first documented mammal extinction due to climate change.
The rat was essentially drowned as sea levels gradually overwhelmed his native habitat. The University of Queensland report points out that seawater claimed about 97 percent of the animal's already minuscule habitat in just about a decade.
"There is almost no doubt the Bramble Cay melomys is extinct, and there is no doubt that this is caused by habitat loss due to sea level rise," James Watson of the University of Queensland told New Scientist.
