This bikini-clad beauty is chumming it up with whale sharks off Mexico.

Anna Harris, 22, filmed herself snorkeling near La Paz alongside the massive sharks, which look vicious but actually have a voracious appetite only for plankton.

“Swimming with the whale sharks was an incredible experience,” the mechanical engineer from California told Caters News.

“It was daunting when I first got into the water and saw a 30-foot shark gliding through the water right in front of me, but they are so docile and calm that it was peaceful swimming alongside them.”

She admitted being nervous when she saw the shark approaching with its mouth wide open.

“Even though it’s a filter feeder, when you’re 5-foot-3 and the whale shark is 30 feet long, it’s pretty startling,” she said.
