There were at least 40 penguin species back then, today there are 17 species of penguin. The Adelie Penguin is the typical looking penguin, purely black and white, with white eye rings. The Emperor and King penguins have yellow-orange neck markings. Penguins are flightless birds. Their wings have been modified to flippers for ocean swimming.
Penguins are gregarious, which means they like to live in community flocks or groups.
Penguin communities are called colonies. Penguins eat fish and crustaceans. Nine species of penguins live in the cool waters south of New Zealand. Seven of the 17 penguin species live mainly in the sub-Antarctic regions, where it is extremely cold. There are several million different penguins inhabiting the coastline of Antarctica.
