After videotaping the swimming of rabbit sperm placed in this chamber, Eisenbach's team concluded that a small share of rabbit sperm, 7 to 17 percent, exhibit a clear preference for moving toward the warmer well, a process called thermotaxis.
They also found evidence of thermotaxis with human sperm.
Komatsu, et al., (9) found that thermotaxis deficient mutants (tax-4) also failed to respond to AWC sensed odorants.
Such thermally acclimated worms migrate toward this preferred (eccritic) temperature (thermotaxis) in a thermal gradient (17).

elegans, it has been shown, by ablating one of the pair of amphidial chemoreceptors or thermoreceptors, that signals from lateral receptors may be pooled for nematode chemotaxis or thermotaxis
(Bargmann and Horvitz, 1991; Bargmann et al., 1993; Mori and Ohshima, 1995).
The neural pathway for thermotaxis
includes the sensory neuron AFD and the connected interneurons AIY and AIZ (Ref.
