Worm grunters drive a 2-foot stob (a wooden peg or stake) into the ground and rub metal against it. Talented individuals, who have learned the art from their ancestors, can summon 3-4,000 nearly foot-long worms in a few hours.
After World War II, recreational fishing and the demand for bait increased. In the 60s and 70s worm grunting became so profitable that the IRS started investigating unreported incomes. Local economies developed around worm grunting and Florida’s panhandle became the epicenter.
It’s such a cultural phenomenon that the town of Sopchoppy, Florida hosts an annual worm grunting festival. Called the Worm Gruntin’ Festival, it features live music, a Worm Grunter’s Ball, food vendors, a 5-K race, arts and crafts, and a ceremony to crown the annual Worm Gruntin’ King and Queen. The first festival took place in 2000.
Charles Darwin was obsessed with earthworms himself and remarked that they sometimes left their burrows when the ground trembled. Over a century ago, Darwin tested worms’ sense of hearing by loudly playing a metal whistle, bassoon, and piano, but all this boisterousness didn’t elicit a response. However, when Darwin placed the worms on the piano, they appeared to be extremely sensitive to the vibrations it produced. This is because worms don’t have ears, but they do take in information through touch, by sensing vibrations.
And in his notes, Darwin alluded to an interesting hypothesis: worms flee the ground in response to vibrations because they “believe they are being pursued by a mole.”
Darwin tried beating the soil with a spade but didn’t get results, though he admitted he may have hit the ground “too violently.” Darwin had essentially attempted worm grunting, but apparently, he’d botched the job. Fast forward many years later–Catania decided to pick up where Darwin left off and further investigate the mole hypothesis. Learn more and Dr. Catania and his lab here.
