This is especially useful when penguins dive deep and they have to battle the current and pressure of water to move further. There are around 17 different types of penguins, and these species are all non-flying. This behavior is commonly seen when penguins come ashore onto rough or high terrain such as ice floes and rocky shorelines. The penguins on the boundaries of the huddle continually move into the more sheltered interior, giving each penguin in the huddle equal access to warmth and benefit from huddling. The team also fitted them with time-budget devices that track those activitiesrecording movements, speeds, and other data much like pedometers do.
