Man Catches Terrifying Underwater ‘Leech-nado’ On Video

Sometimes it’s difficult to know what lurks beneath the surfaces of freshwater ponds and lakes—their water made so easily murky by mud, silt, and underwater life. However it’s a safe bet that there could be leeches—and it’s enough to make us all a little wary of taking a refreshing dip in the water.

YouTube user Solomon David discovered a body of water so terrifying and infested with leeches that he chose to title it “Leech-nado.”

Apparently he was filming in an area of wetlands near Green Bay, Wisconsin when he decided to capture some underwater footage. What he saw were hundreds of wriggling leeches clouding in the water.

According to David this is the first time he’s found leeches at that site, and he suspects that the swarm will disperse as the weather improves. He said that while he’s seen many fishes at the site over the years, he’s never seen leeches in such huge numbers.

David is an aquatic ecologist with the Daniel P. Haerther Center for Conservation & Research at the John G. Shedd Aquarium. He works jointly with the University of Wisconsin-Madison Center for Limnology.

According to his YouTube profile, his research involves conservation ecology of Great Lakes fishes, specifically migratory varieties like Northern Pike and Lake Whitefish.
