Little penguins are the smallest of the 17 penguin species in the world. They are found only in southern Australia and New Zealand, living in burrows on land where they raise their young while spending between one day and four weeks at sea fishing. Unlike some other penguins, little penguins do not typically mate for life, with an annual divorce rate between 18-50%. The document encourages supporting conservation efforts for little penguins through adoption on the listed website.
