A jellyfish sting has ended Australian endurance swimmer Chloe McCardel's attempt to become the first person to swim from Cuba to Florida without a protective shark cage.
The "debilitating" sting forced her to abandon the 166km (103-mile) swim after 11 hours, her support team said.
It added that the athlete would need 24 hours to recuperate from the severe injury.
