Amorphophallus titanum and the essence of rotting fish

Have you heard of the corpse flower? Scientifically known as Amorphophallus titanum, the corpse flower gets its name because it generates a variety of malodorous compounds to attract animal pollinators. Among these is trimethylamine, or "essence of rotting fish" (Fig. 1), a biomarker used by fish freshness detectors.

An excellent short video here on these compounds and the ability of the corpse flower to generate heat!
