This paper describes the hydrodynamic function of minute hairs of living creatures. Many living creatures have minute hairs on their bodies. The swimming analysis of small aquatic creatures and the sinking analysis of dandelion seed were performed using a digital high speed video camera system. Microscopic observation of swimming legs of small aquatic creatures and pappus of dandelion seed was conducted using a scanning electron microscope. Flow visualization around a opossum shrimp was conducted by slow shutter photographic technique. The role of minute hairs for hydrodynamic drag generation was revealed through these analyses.
