The smallest species of penguin is the Little Blue Penguin, also known as the fairy penguin. These charming birds typically weigh around 1 to 1.5 kilograms (2 to 3.3 pounds) and stand about 30 to 40 centimeters (12 to 16 inches) tall. Native to the coastlines of Australia and New Zealand, Little Blue Penguins are known for their distinct blue plumage and adorable, waddling gait. They primarily feed on fish and small marine creatures, using their excellent swimming skills to catch food in the water. Their small size and unique characteristics have made them a favorite among wildlife enthusiasts.
