Deep Blue, however, is not a baby. She is a roughly 50-year-old shark who can literally hug you to bits with her mouth. So you probably wouldn't want to get too friendly with her if ever you crossed paths. Yet when 50-year-old behemoth Deep Blue was first discovered near the Mexican island of Guadalupe in 2013, one diver felt so comfortable that he reached out and touched her. That someone was shark-ologist Mauricio Hoyos Padilla, who gave Deep Blue her nickname. In a video clip of their encounter first released in 2015, a fearless Padilla "high-fived" one of Deep Blue's fins. Cool, yeah, who really needs both of their hands? more
