Wild Marine Turtle Hatchling Light Disorientation

Artificial coastal lighting disorients sea turtle hatchlings, causing mass mortality.

Key Facts

Hatchling turtles instinctively move toward the brightest horizon — normally the sea
Artificial lighting causes hatchlings to move inland, where they die from exhaustion
Florida reports thousands of disorientated hatchlings annually
Amber lighting and shielding can largely eliminate the problem

Welfare Considerations

Hatchlings moving inland in response to artificial lights experience exhaustion, dehydration, and death. This happens across millions of individual hatchlings on beaches around the world. Each hatchling that travels inland rather than into the sea suffers and dies unnecessarily. Simple lighting modifications can prevent most of this suffering.

What You Can Do

Support turtle-friendly lighting ordinances on nesting beaches
Turn off or shield coastal lights during turtle nesting season
Volunteer with sea turtle nest monitoring programmes
Choose coastal tourism operators who follow turtle-safe practices
