When doing it for The Gram goes way wrong!
Katarina Zarutskie was on vacation in the Bahamas with her boyfriend and his family when she posed with sharks for her Instagram page.
Suddenly, a shark bites her arm and drags her underwater. After a scary struggle, the girl was able to free herself, but she was left with a giant gash on her arm.
“It was a very scary experience,” she said during an interview. “I was pulled underwater for 8 seconds.”
