Four of the six nuclear reactors at France's Gravelines nuclear power plant were shut down after an intake pipe used to draw water for cooling from a canal became clogged with jellyfish, Reuters reported.

Recently, a face-off took place between jellyfish and a nuclear power plant, with the former pulling out a win. The incident unfolded in Gravelines Nuclear Power Station in France, according to Futurism.

Four of the plant’s reactors shut down after swarms of jellyfish clogged its pumping stations. It isn’t the first time the creatures have thwarted nuclear plants.
