... will be approximately the mean of the two pre-synchronisation frequencies, because the slower flagellum tends to decelerate the faster one whereas the faster one tends to accelerate the slower one ( Gray,1930 ; Machemer,1974 ). In the present study, flagellar synchronisation between pairs of bull spermatozoa has...

...D. M. Woolley; G. G. Vernon ABSTRACT When the spermatozoon of Echinus esculentus swims in sea water containing methyl cellulose (viscosity 1.5–4 Pa s), its flagellum may generate either a helical or a planar waveform, each type being stable. The helical wave, which is dextral, is complicated...
