In an absolutely fascinating, yet somewhat bawdy episode of the True Facts series, the hilariously deadpan Ze Frank (previously) explains everything about the intricate stinkhorn fungus (Phallaceae).
The stinkhorn creates egg-like spores that emit a smelly gleba that attracts all sorts of insects. The insects gobble up the gleba and spread the spores wherever they go. After that, the stinkhorn bursts open into a hook-shaped flower of sorts.
