Sea turtle

''"How did you escape Davy Jones?" " Sea turtles. I paired them up and strung them to my feets!" "Not as easy as it seems, aye, mate?"

Sea turtles are a species of marine reptile. In Pirates of the Caribbean, characters who manage to escape islands where they were deserted or other such places tell others that they escaped with the help of sea turtles.

It's possible that the term means that a ship picked one up, as it happens first to Jack Sparrow prior Pirates of the Caribbean: The Curse of the Black Pearl on Rumrunners' Island after the mutiny on his ship and to on the same island with both Jack and Elizabeth Swann. It also happens to Will Turner after his escape from The Flying Dutchman. It´s possible that the Prison Dog, who was Jack Sparrow's successor as chief of the Pelegostos, were picked up by Teague Sparrow, as he tells the pirates that the dog escaped by using sea turtles in Shipwreck Cove in the third movie At Worlds End.
