emperor penguins, like other birds, have the capacity to fluff their feathers and insulate their bodies with a layer of air. but where most birds have rows of feathers with bare skin between them, emperors have a dense, uniform coat of feathers with tiny filaments at the base which allows them to release this air as lubricating microbubbles. this acts to reduce viscosity and cut drag, thus enabling the penguins to reach speeds of twenty seven feet a second and fly out of the water and over any potential waiting leopard seals.
