The incident happened at Ripley's Aquarium in Toronto Friday.
Amazingly, the sharks pretty much ignored the man, rather than treating him like a surprise snack.
Security guards were able to eventually coax the man out of the water, but he took off before police arrived.
Authorities were able to track him down and arrest him Tuesday.
Investigators say two hours before the bizarre incident, the same man assaulted someone outside of a medieval fair.
