... of turning manoeuvres is not well understood. In this study, we examined the horizontal turning of penguins via 3D motion analysis and quasi-steady hydrodynamic analysis. Free swimming of gentoo penguins ( Pygoscelis papua ) at an aquarium was recorded, and body and wing kinematics were analysed. In addition...

...Eize J. Stamhuis; John J. Videler ABSTRACT The morphology of the pleopods, uropods and telson of the tube-dwelling shrimp Callianassa subterranea have been studied using dissection microscopy and scanning electron microscopy. The kinematics of these appendages were examined by motion analysis...

When swimming speeds were measured using a computerized video motion-analysis system, a highly significant difference ( P <0.0001) between cells at the two depths was found. Cells nearest the lid swam at 174.6±5.9 μm s −1 (mean ± S.E.M...
