On the Dancing With the Stars Season 18 premiere, long distance swimmer Diana Nyad and new pro Henry Byalikov danced the Foxtrot.

In her video package, Diana called herself the number one fan of the show. Diana is very determined, but Henry says she's a bit of a fish out of water on the Foxtrot. She does not like heels, which is hard. Her motto is "find a way." She never, ever gives up.

Her performance is elegant, but pretty stiff and slow. We like her attitude, but this is not a fantastic performance.

Bruno called her the million dollar mermaid. He said she didn't do badly, but needs to be lighter and smoother. Carrie Ann called her a slowly opening flower, and said she got more comfortable as it went on. She needs to work on her feet. Len tells her it needs more finesse, but he didn't expect it to be as good as it was.

Score: 18/30.
