How deep can penguins dive?
Emperor penguins can dive 564 meters deep and stay underwater for 20 minutes.
Their bodies handle extreme water pressure and low oxygen levels. They store extra oxygen in their muscles and slow their heart rate to save energy. This lets them hunt for food in deep water where other birds cannot go.

Emperor penguins are the deepest-diving birds on Earth. In 2011, researcher Paul Ponganis recorded a penguin diving 564 meters deep. At that depth, the water pressure is 50 times higher than at the surface. This pressure would crush a human's lungs instantly.Most birds have hollow bones to help them fly. Emperor penguins have solid bones that are heavy and strong. These bones help them sink and prevent injuries from the high water pressure. They also have special blood that carries more oxygen than human blood.During a dive, a penguin can slow its heart rate from 100 beats per minute to just 6 beats per minute. This sends oxygen only to the brain and heart. Their muscles also hold 10 times more oxygen-storing protein than land animals. These tools allow them to hunt for squid and fish in the dark, deep ocean.
