How do balls of worms untangle? Harry Tuazon of the Georgia Institute of Technology in America has found that a ball of worms can untangle in milliseconds with a corkscrew wiggle.

What does this mean? And why is it important to know?

Researcher Harry Tuazon studied California Blackworms (Lumbriculus variegatus). He found that they tangle themselves into a ball to preserve moisture during droughts. He calls these ‘balls’ of worms knotted ‘worm blobs.’ In the wild, these balls can have up to 50,000 individual worms.
