The Answer

The question in this edition is:

What has kept the penguins of southern Australia from going extinct?

The answer: Sheepdogs

The penguin population on Middle Island off the coast of Victoria, Australia, was down below 10 animals when a local farmer had the brilliant idea to have sheepdogs stationed among the penguins to scare away the foxes that were eating the penguins. The population is now back in the hundreds. The fox was introduced by colonists in the 1700s, along with a number of other non-native species, which have caused the extinction of many indigenous Australian species.
