Talk about fearless! Texas resident Eli Martinez has been swimming with sharks for over 20 years now.

The 47-year-old says it's his favorite thing to do according to an interview with KCENTV. Eli has his own magazine, blog, and excursions that he uses to try and shed light on what he says are some rather misunderstood predators. Eli is trying to pass on his knowledge to his children by getting them involved in his work.

Martinez has never been attacked by any of the animals that he observes underwater or on land. He plans to spend more time with the hammerhead sharks this month.
