Did you know:
*Penguins have been around for about 40 million years. The earliest penguins appeared in the Paleocene period in New Zealand. They appear in Antarctica in the Eocene.
*Penguins mate for life.
*Penguins can swim up to 25 miles per hour, though 15 miles per hour is the average.
*There are 17 or 18 different species of penguin in the world. There is debate about whether Little Blue and Fairy penguins are separate species.
*The average penguin spends 75% of its life in the water.
*Early explorers of the Antarctic mistook penguins for fish (and classified them as fish). Penguins are birds.
*Large, dense colonies of penguins are called rookeries. Penguins gather in rookeries to breed.
*There are no natural penguin populations in the northern hemisphere.
*Penguin eyes are made for seeing underwater. They work better under the water than they do in the air. This adaptation is likely due to the fact that penguins feed in the water, hunting fish and krill.
*Most wild penguins live 15-20 years.
