Madagascar Hissing Cockroach
Gromphadorhina portentosaGreen
The Madagascar Hissing Cockroach carries the forest floor on its back, armored in glossy brown plates and built for life among bark, leaves, and fallen wood. Unlike many cockroaches, it has no wings, relying instead on a tough exoskeleton, gripping feet, and the ability to squeeze into narrow shelter.

The animal behind the card
Its famous hiss is produced by forcing air through breathing openings, creating a sharp warning or display that can startle rivals and predators. Groups gather around food and cover, feeding on decaying plant matter and helping recycle nutrients through the island forests they come from.
The species often surprises people because it is more deliberate than frantic, more like a slow armored browser than a household pest. The Madagascar Hissing Cockroach turns decomposition into quiet work, breaking down what falls from the canopy and returning it to the living soil.
Bestiary facts
