After a sea turtle hatchling scurries down the beach and plunges into the waves, it vanishes into the ocean, remaining incognito for the next few years.

This early period of a sea turtle's life history, often referred to as the 'lost years', has long intrigued scientists, leaving many questions about this mysterious stage.

Where do these hatchlings go? And when do they transition from being 'lost' to 'found'?

"The majority of flatback hatchlings are retained in the neritic environment, or what we call the shallow waters of the coast", explains Dr. Sean Williamson, a Field Biologist and Researcher at Monash University, Australia. "As opposed to loggerhead hatchlings on the East Coast of USA, which drift in the Gulf Stream all the way across to the other side of the Atlantic Ocean until they get around in line with France".

But how do these tiny travelers navigate such long journeys?

Tune in to the fifth episode of Sea Turtle Stories as Dr. Sean delves into the 'lost years' of sea turtles. He reveals insights from his research, covering everything from hatchling dispersal patterns and their extraordinary navigational skills to the innovative technologies used to uncover these mysteries.
