A raft is a group of penguins in the water; a waddle is a group of penguins on land.
The black and white "tuxedo" look that most penguin species wear is a smart camouflage technique known as countershading.
This behaviour aids these birds in their defence against predators. Huddling helps penguins keep warm in cold environments.
Most birds have hollow, air-filled bones that let them fly light. Instead, penguins evolved with solid bones. Because solid bones minimize buoyancy.
A gland near the base of its tail produces waterproof oil. Penguins spend several hours each day coating their feathers with this oil.
Antarctica and its islands, the Galapagos Islands off the coast of Ecuador, South Africa, New Zealand, Australia, Peru, and Chile are all home to them.
Because penguins live south of the equator and polar bears live north of the equator in the Arctic!
Some species can march up to 60 kilometres through sea ice to reach their nesting habitats. They angle their feet like rudders to help control direction.
To woo female penguins, many male penguins present them with rocks. These rocks are used by the ladies to construct a nest.
Penguins have a rapid metabolism, which means they need to poop frequently.
That's only 3 million years after the dinosaurs became extinct!
