Lars Lundqvist, 54, said he woke early Wednesday at his home on the island of Gotland and decided to photograph the unusual weather, The Local.se reported Wednesday.
"It was very dramatic out there and I thought I'd take a few stills, but then after 15 minutes I saw a weird, grey pillar and I thought: 'What the hell is that?'" Lundqvist said.
He soon realized the pillar was a liquid tornado.
"I was surprised. I've never seen one over the sea before. It was impressive, particularly so with that rainbow there. It was great scenery, magnificent really," he said.
Lundqvist said the waterspout was not filled with sharks, as in the recently released cult film "Sharknado."
"I was looking for sharks," he joked. "But I didn't see any. I didn't see any flounders or cod either actually. Nothing. I felt very safe."
