Ducks Can Detect Tiny Water Ripples From 30 Meters
A duck's bill contains thousands of tiny pressure sensors that feel the slightest water movements created by swimming insects or fish. These sensors work like living radar, letting ducks locate hidden food even in murky or dark water.
💡 Fun detail:
Scientists tested this ability by dropping a single grain of rice into a pond and watching wild ducks swim straight to the spot within seconds.
