The primary skeletal structure used by dolphins to generate the dorsoventral bending characteristic of cetacean swimming is the vertebral column. In the vertebral column of the saddleback dolphin Delphinus delphis, we characterize the static and dynamic mechanical properties of the intervertebral joints, describe regional variation and dorsoventral(More)
To evaluate the versimilitude of theoretical and mechanical models of fish and fish-like propulsive systems, we compared quantitatively the motion of undulatory body waves using a Fourier-based method. The undulatory motions of a freely-swimming lamprey were compared to a series of theoretical and physical models. For each swimming trial, Fourier series of(More)
