Bioluminescence in the ophiuroid Amphiura filiformis (O.F. Müller, 1776) is not temperature dependant

Influence of temperature on the bioluminescence in the ophiuroid Amphiura filiformis was experimentally tested. Amputated arms from individuals acclimated at 6° or 14° were incubated at five different temperatures ranging from 6° to 14° for 2 hours before KCl stimulation. Light response comparisons do not reveal any difference neither for the two temperatures of acclimation nor for the five temperatures of incubation. Therefore, the temperature does not affect the studies parameters of the light emission.
