A 62-year-old woman is trying to complete a record swim from Cuba to Florida for a third time.
Diana Nyad hopes to complete the 103 mile journey on Tuesday.
She's swimming outside of a shark cage and faces muscle fatigue.
On Sunday, a storm blew her off course and into a school of jellyfish.
Nyad is being followed by an electronic device stored in a kayak that is supposed to keep the sharks away.
The device generates and electric field that is not noticeable to humans.
