Okinawa spiny rat
Nobody knows how many of these rats survive, but their population is concentrated in a borough-sized area of Okinawa.
"Each species expresses a solution to a set of very specific environmental conditions," said John Robinson, executive vice president of the Wildlife Conservation Society, in the report. "They allow us to turn away from our parochial needs and desires, and play on the larger stage of biological richness and variety. We owe it to ourselves, and to them, to find room on this planet for all of them.”
