✦ Synopsis

Abstract

Mechanically stimulable bioluminescence and photoinhibition of sensitivity to mechanical stimulation in the marine dinoflagellate Gonyaulax polyedra can be mimicked by a number of cations, proportional to the logarithm of their external concentrations. The data are consistent with mechanical stimulability as a membrane depolarization resulting in an increase in H^+^ions at bioluminescence sites and with photoinhibition as a hyperpolarization of the cell membrane.

## Abstract The mechanically stimulable bioluminescence of members of the __Gonyaulax catenella__ group can be maximally photoinhibited by exposure to as few as 10^13^ quanta/cm^2^, a factor 10^4^ times smaller than that required for comparable photoinhibition in __Gonyaulax polyedra__ and all othe
