Chapter 1 introduced a general outline of the basic theory required for studying biokinetics, touching on the fluid-dynamic characteristics of air and water to help the reader understand the dynamic behavior of living creatures of various configurations that dwell in different environments and pursue diverse modes of life. By treating the equations of motion representing the physical and kinematical phenomena in a nondimensional form, it is possible to clarify the generalized rules of motion and the modes of locomotion in a unified form for various sizes and even for different species, and thus to characterize the motion of living creatures by a few fundamental nondimensional parameters, such as Reynolds number, reduced frequency, and Froude number.
