The manicure helping to save the rarest of bats

One of the world's rarest bats is now confined to a single cave in Western Cuba with less than 750 remaining, according to a population survey. Scientists are highlighting the plight of the animal, saying its last home is vulnerable to collapse. The Cuban greater funnel-eared bat was rediscovered in 1992 after being declared extinct.
