"To coddle fragile items, we might consider the strategies of seed helmets--nuts. The Brazil nuts in your holiday bowl were once packed in a 3-layer, highly reinforced pod that survived an 80-meter fall from the canopy. On the ground, the pod defies opening from all but its ally, the agouti, a caching rodent with strong, angled teeth." (Biomimicry Guild unpublished report) Edit References
