A Brazilian fisherman miraculously survived after spending 11 days in shark-infested waters in a freezer after his boat sank.

Romualdo Macedo Rodriguez's ship started sinking while in the Atlantic Ocean off the coast of northern Brazil.

According to CNN, he feverishly climbed inside a huge freezer and spent 11 days there until he was picked up by another boat off the coast of Suriname.

According to him, the sharks circled the freezer, but did not attack, and he had to bail out water with his hands every time she filled the freezer.

Just as his struggle for survival began to fade, a lifeboat appeared.
