It's official, Olympic swimmer Michael Phelps has teamed up with the Discovery Channel and will test his speed against a great white shark on Sunday during "Shark Week."
"This has been something I've wanted to do my whole life," Phelps told "GMA." "This has been on my bucket list a long time and you know, being able to see these animals up close and personal in their own environment is something that was just such a treat."
To get ready for the big event, I've pulled some of Circa's best animal videos.
"Phelps Vs Shark: Great Gold Vs Great White" airs July 23, the first night of Shark Week, at 8 p.m. ET.
