The shortfin mako (Isurus oxyrinchus), great white shark (Carcharodon carcharias), and blue shark (Prionace glauca) use bouts of gliding and upswimming in undulatory
patterns over tens of meters (Klimley et al.
The occurrence of polycrystallinity and undulatory
extinction in quartz in sandstones.
Members of the newly found species swam with an undulatory
motion and presumably were too slow to pursue prey, says Nicholls.
Dynamics Behavior and Experimental Research of Bionic Underwater Vehicle Propelled by Undulatory
9), and many have deformation twins, serrated margins, undulatory
extinction, and/or brittle fractures.
3 [micro]m, contained a thin-walled sporocyst enclosing eight sporozoites and a large residuum, and possessed a thin, undulatory
The result of such a chain of events is the undulatory
movement that leeches use to swim.
But the results surprised us because the density of the granular media did not affect how the sandfish traveled through the sand; it was always the same undulatory
wavelike pattern," he added.
Anhedral quartz grains commonly show undulatory
As a result of undulatory
movements accompanied by wave resistance, the shape of the fin surface changes, causing a negative phenomenon.
Apart from some minor undulatory
extinction in quartz there is little evidence of any solid-state deformation, and we agree with Trefethen (1944) that the foliation is principally magmatic in origin.
