On Japan's rice farms, tiny shrimp fight weeds naturally

One of the all-natural techniques that Japan's rice farmers use to control weeds in their paddies is the tadpole shrimp.

This tiny crustacean controls weeds in three ways:

by uprooting small weed seedlings, by agitating the soil surface so that the water becomes muddy, thereby inhibiting photosynthesis of small weed seedlings, and—last but not least—by eating young buds and roots of plant seedlings.

Aw, what a cute little feller. And useful, too.
