DALLAS (KRLD) – Eli Martinez is getting a lot of reaction to a video he posted on Instagram 10 days ago.

“It’s video of a tiger shark named Jenn at Tiger Beach in the Bahamas,” Martinez says.

At first, it appears to be a normal underwater video of a person swimming near sharks … until, suddenly, it’s not.

The video shows Martinez using a crate to playfully dance with the Jenn the shark.

“We bring a small crate with some snacks in it. This keeps the sharks focused on a general area,” Martinez says. “We line up photographers. I’ve learned how to play with sharks and work with them. This tiger shark came in for a snack and I gave her a nose rub. I could tell Jenn was interested in playing. So we sort of danced together for a bit.”

Martinez says he’s not afraid of the sharks, however, he does say that you must respect the sharks.

Martinez says he was excited to “share this side of sharks … I think it’s fantastic.” He has a business called SDM diving where he takes people on expeditions.
