Abstract:
A swimming creature simulator consisting of:a unitary elongate body of elastomeric material, said unitary elongate body approximately as dense as water and comprising a front tip, a forward portion forward of the center of mass of said elastomeric body, a rearward tail portion rearward of the center of mass of said elastomeric body, a rear tip, and a top and bottom, said rearward tail portion tapered rearwardly in a frontal plane of said unitary elongate body so as to have a greater cross-sectional thickness toward the center of mass than at said rear tip; andmeans for imparting oscillating rotational motion at a point forward of the center of mass of said unitary elastomeric body, said rotational motion occurring about an axis perpendicular to said frontal plane and lying in the median plane of said elongate body,wherein when said unitary elastomeric body is placed in water, said oscillating rotational motion causes rearward traveling undulating movements of said elastomeric body which propel said elastomeric body through the water.
