It was the first body recovered since May 21.
A government task force said in a statement that fingerprint scans identified the body as one of passengers from the ferry that sank April 16.
Another 15 people remain missing. Heavy objects like desks and cabinets have made it difficult for divers to navigate through unsearched parts of the ferry. They have been cutting open parts of the ship exterior to make searches easier.
Most of the ferry victims were students from a single high school near Seoul who were on a school trip to Jeju.
