Presenting... the dung canon (Pilobolus crystallinus). This tiny fungus crops up in the dung of grazing animals, and while only 2-4 cm tall, can shoot its spores up to 2 m away at an acceleration of a whopping 20000 g. If successful, these spores will stick to nearby vegetation and be consumed by the grazers once again, allowing the dung canon to complete its rather odd life cycle.
