20 Francs Falkland Islands Wolf

The Falkland Islands wolf — also called the warrah — was the only native land mammal of the Falkland Islands and was hunted to extinction by 1876, largely by European settlers who considered it a threat to sheep. Darwin encountered it during the Beagle voyage and remarked on its unusual tameness toward humans, which he attributed to its having evolved without terrestrial predators. That behavioral trait made it trivially easy to kill.

The Democratic Republic of Congo has issued wildlife-themed commemoratives under its KM#316 series for foreign markets, with no meaningful connection to the depicted species.
