Pedro Serrano

Pedro Luis Serrano, also referred to as Pedro de Serrano, was a 16th century Spanish sailor who was allegedly marooned for seven to eight years on a small desert island. Details of the story differ, but the most common version has him shipwrecked on a small island in the Caribbean off the coast of Nicaragua, sometime in the 1520s. Serrano survived by eating shrimp, cockles, and other animals he found washed up on the shore, and by collecting drinking water in sea turtle shells when it rained. When rainwater was unavailable, he also drank the blood of the turtles he had captured.
