The life cycle of a sea turtle is fascinating and mysterious. This video from Nature explores the role that Cuba’s beaches play in the lives of sea turtles: how they nest, how they return to the same beaches year after year, and how they recognize the beach by the scent of the sand. The video also examines the threats facing sea turtles, and the efforts Cuban biologists are taking to help them.

This video is available in both English and Spanish audio, along with corresponding closed captions.
