Terrestrial locomotion in penguins: it costs more to waddle.

B Pinshow M A Fedak K Schmidt-Nielsen

Science

Published: February 1977

The morphology of penguins seems to represent a compromise between aquatic and terrestrial locomotion wherein both energy economy and speed suffer when the birds move on land.
