The All-Purpose Foot

The All-Purpose Foot

On today’s Creation Moments Minute, find out how a lowly underwater creature has become the master of biological adhesives!

Nothing is harder on an adhesive’s ability to stick than water. But the lowly mussel has figured it all out. Its foot acts like a rubber plunger, first cleaning the spot and then flattening against the surface to pump the water out. Next, the mussel lifts the center of its “plunger” and creates a small vacuum. Now the ingredients for its adhesive are pumped down through the foot and into the vacuum. The glue is made of several proteins that provide just the right amount of strength, flexibility and resistance to compression needed for each unique anchoring spot.

The mussel is not only a wonder of design, but a sophisticated chemist as well. Modern science is still trying to learn what the Creator has taught the mussel about glue.
