Brought to my attention by my marvelous wife.

What you see below isn’t a fish but in fact the freshwater plain pocketbook mussel (Lampsilis cardium) displaying her lure mimicking a fish. This sacrificial body part serves to attract a predatory fish and, when chewed upon, will rupture and release parasitic larvae inside said chewer. These larvae attached to the host’s gills will then feed and develop and y’know, live their life at the expense of somebody (just not their parents) until they’re ready to leave.

Okay, that’s not really rpg-related but cm’on! Baiting and parasitism all in one? It begs to be adapted into a monster!
