...Isaac J. Yeaton; Shane D. Ross; John J. Socha ABSTRACT Flying snakes (genus Chrysopelea) glide without the use of wings. Instead, they splay their ribs and undulate through the air. A snake's ability to glide depends on how well its morphing wing-body produces lift and drag forces. However...

... State Reserve, CA, USA. The seals moved using a series of rhythmic undulations produced by dorsoventral spinal flexion. The traveling spinal wave moved anteriorly along the dorsal margin of the body with the chest, pelvic region and foreflippers serving as the main points of contact with the ground...

...Erin L. Blevins; George V. Lauder SUMMARY Rajiform locomotion in fishes is dominated by distinctive undulations of expanded pectoral fins. Unlike other fishes, which typically interact with the fluid environment via multiple fins, undulating rays modulate a single control surface, the pectoral disc...

... stresses that generate skin friction are located in the anterior region (Anderson et al., 2001). The degree to which the lateral line system affects the lateral amplitude of undulation depends on swimming speed. At the higher speeds considered here (11 and 22 cm s −1), ablating the lateral line...
