Fluorescing mantis shrimp catching a fish

Fluorescence video of a mantis shrimp (stomatopod) spearing a fish. This video was taken at night using blue light that causes the fluorescence of the yellow patches on the mantis shrimp. It was just good luck, for me and the mantis shrimp, at least, that this foolish fish came by (three times!) and I was able to catch the video of the strike.
