— The luminescence of freshly collected exudate from the post‐cleithral organ of the deep‐sea searsiid fish. Searsia koefoedi , was increased in intensity by the addition of hydrogen peroxide and exhibited emission maxima at 408 nm and 478 nm. Initially, the spectrum was unimodal with a long wavelength peak and a short wavelength shoulder. With time, the short wavelength peak increased in relative magnitude; the spectrum became bimodal, then the short wavelength peak predominated. The measured time‐dependent changes in the spectral distribution resulted from differences in the rates of decay of the two peaks. The short wavelength peak exhibited first order exponential decay with a mean (± standard deviation) decay constant of ‐0.13 ± 0.02 min ‐1 ( N = 4). Decay of the long wavelength peak proceeded approximately twice as fast and was best defined by a double exponential function.
