A particular plant in Africa secretes sap that elephants love.
The elephant eats the bark, and at the same time swallows the plant’s seeds.
The elephant then continues walking.
The seeds are eventually pooped out far away from the plant.
The predatory thought is that the plant gets its seeds distributed far and wide, ready-wrapped in a ball of manure, using the elephant as a delivery vehicle.
