Snorkelers expect to find fish and other marine life while out on the water -- but not this.

The Monroe County Sheriff's Office said a person was out snorkeling in the waters off the Florida Keys on Wednesday afternoon when they came across a large black bundle wrapped in tape that was floating in the water.

The snorkeler called the sheriff's office, who notified U.S. Border Patrol.
