A recent experiment at the London Zoo undertaken by and (of the University of Texas at Austin) is featured in . The experiment involved recording the forces that penguins exerted with their limbs against the ground as they walked along a corridor in their enclosure. The aim was to obtain a complete biomechanical picture of walking in penguins, looking at how their bones, ligaments and muscles produce penguins’ distinctive off-kilter gait.
