Swarms of jellyfish threaten to shut down the Orot Rabin nuclear power plant in Hadera, Israel. The jellyfish are blocking the plant's water supply, interrupting the cooling process.
Workers have been removing the jellyfish to prevent the reactors from being shut down.
Last week, a nuclear power station in eastern Scotland had to shut down its reactors after jellyfish blocked its seawater filter screens.
