Penguins achieve these incredible speeds due to their unique anatomy, which includes: A torpedo-like body shape including legs placed far back on their bodies which results in remarkably little drag the legs only being used for steering when swimming ; Flattened and rigid wing bones, the arrangement of which unlike in flying birds create significant forward propulsion on both the up and down-stroke; A silky outer layer of feathers; and Heavy non-pneumatic bones, so the birds are not fighting buoyancy in the way flying birds would.
The public are also invited to get involved thanks to two public events this week. There will also be an opportunity to learn more about the African penguin at Bristol Zoo Gardens on Saturday, 7 September, with activities for all the family and the chance to meet scientists and conservationists who work with African penguins in South Africa and Namibia.

Other species are unable to use all the oxygen in their lungs, even when starved for air, because their haemoglobin cannot efficiently bind with and carry oxygen in low concentrations.
This would allow it to use its lung oxygen completely and would also provide a greater oxygen content at low oxygen pressures so that there is no tissue damage," National Geographic quoted the lead author Paul Ponganis of the Scripps Institution of Oceanography in San Diego, California, as saying. Emperor penguins can manage to dive down to 1, feet meters while searching for fish, squid, and krill in the open ocean.
Such penguins have a variety of adaptations that help them enhance their ability to store oxygen and control its consumption rate. For example, higher concentrations of haemoglobin and the blood protein myoglobin allow emperor penguins to store about 2.
The birds also conserve oxygen by slowing their heart rate to as low as five beats a minute on long dives, even while chasing after fish. The thick layer of sea ice on the ranch is broken only by diving holes drilled by scientists. Since the birds are too far away from other openings, they must return to the same location after fishing trips. The study penguins were equipped with tiny sensors inside their air sacs.
