The reason that the electronic jellyfish worked as a lure is not because giant squid eat jellyfish, but it's because this jellyfish only resorts to producing this light when it's being chewed on by a predator and its only hope for escape may be to attract the attention of a larger predator that will attack its attacker and thereby afford it an opportunity for escape.
Grunden til at den elektroniske gople fungerede som et blink er ikke fordi kæmpeblæksprutter spiser gopler, men fordi goplen kun tyer til at bruge dette lys når et rovdyr tygger på den, og dens eneste håb om redning er at tiltrække et større rovdyrs opmærksomhed som vil angribe goplens angriber og derved give goplen en chance for at slippe væk.
