Most penguins can swim 15 miles per hour.
There may be as many as 100 million penguins in the world.
Penguins use a sign language of sorts to communicate with each other. They will wave their flippers and move their heads to “talk” to other penguins in the group.
Living on the ice can be quite dangerous, with natural predators lurking around each corner. Because of this many penguin species don’t go back on the ice or dry land to sleep. Instead they take little naps in the water instead.
