Sharks have survived five global mass extinctions yet, now, many of their species are endangered due to human activities and myths. Cristina Zenato works to reverse this. She is an ocean and cave explorer, shark behaviorist and expert, dive instructor, speaker, writer, and a conservationist. She has helped to change the perception about sharks through the close encounters she has with these animals. They often allow her to pet them and even remove hooks from their mouths! Cristina was a vital player in helping to declare the Bahamas as a shark sanctuary when external fisheries were looking to come in and take them from Bahamian waters. But she also works all over the world advocating for these often maligned creatures and for the conservation of the waters they live in.
