Changes in size strongly influence organisms’ ecological performances. For aquatic organisms, they can transition from viscosity- to inertia-dominated fluid regimes as they grow. Such transitions are ...

A new computational analysis suggests that maximizing swimming speeds while minimizing energy costs depends on an optimal balance between a fish's muscle dynamics and the way its size, shape, and ...

Take your hand and draw it through water in a pool. You can feel resistance---this is hydrodynamic drag. It is the effective force created by the interaction of your body and the water. Swimmers push ...
