fin - organ of locomotion and balance in fishes and some other aquatic animals caudal fin, tail fin - the tail of fishes and some other aquatic vertebrates fishbone - a bone of a fish Pisces - a group of vertebrates comprising both cartilaginous and bony fishes and sometimes including the ...
Fishes also usually have unpaired dorsal and anal fins, which serve as stabilizers and, less commonly, as organs of locomotion (for example, the anal fin of the electric eel). In males of Cyprinodontiformes part of the anal fin serves as a copulatory organ. The caudal fin varies in shape...

Here we show that the thick subcutaneous layer (or 'capsule'), already known to provide positive buoyancy, is also crucial to locomotion. It provides two compartments, one for dorsal fin musculature and one for anal fin muscles, separated by a thick, fibrous, elastic horizontal septum that is...
Locomotion of the coelacanth Latimeria chalumnae in its natural environment The coelacanth Latimeria chalumnae is the only living relic of a fossil group of crossopterygian lobe-finned fish 1–4 . We describe observations of its l... H Fricke,O Reinicke,H Hofer,... - 《Nature》 被引量: ...
However, there were significant changes in the locomotion of the fish after feeding under the RF EMF.The locomotion of the fed fish was affected in terms of changes in population and velocity distributions under the presence of the RF EMF emitted by the cell phone. There was, however, no ...
Thus, for locomotion on land, as well as in water, it is possible to follow the gradual transitions between simple reptation and the more complicated kinds of locomotion. An eel and an adder put in water, progress in the same way; a wave of lateral inflexion runs continually from the ...
the cost of transport given by the ratio between expended power and locomotion speed2,3, is no longer a priority so that different measures are needed to search for optimal performances. The most common fast start swimming gaits were largely described in a survey paper by Domenici and Blake4...
It is doubtful whether those earliest carts were ideal instruments of locomotion. People rarely used them unless they were obliged to do so through sickness or old age.Whenever possible, they stuck to the backs of horses and mules.Then came the period of neglect, which followed in the wake ...
