A French swimmer has set off from Japan aiming to become the first person to swim across the Pacific Ocean.
Ben Lecomte, 51, will swim for eight hours a day for more than six months as he heads towards the US west coast.
He faces dangers including sharks, storms, swarms of jellyfish, and extremely low water temperatures.
He is hoping to raise awareness for climate change, and a team of scientists will conduct research during the 9,000 km swim.
