°CTurtles on the Gili Islands | The Turtle Nesting Process Explained
Sea turtles have followed the same ancient rhythms for millions of years. Along the shores of Gili Meno, these cycles continue—largely unchanged, and mostly unseen.
Understanding how turtles nest offers a deeper appreciation of what makes this island one of the most remarkable marine environments in Indonesia.
An Ancient Return to Shore
Sea turtles reach maturity only after approximately 20 years. Once ready, they begin long-distance migrations across the ocean, often traveling thousands of kilometers.
What makes this journey extraordinary is precision.
Female turtles return to the exact beach where they were born. In the waters surrounding Gili Meno, species such as Green and Hawksbill turtles are commonly found, continuing this cycle generation after generation.
The Nesting Process Explained
Nesting occurs at night, when the beach is cooler and less exposed.
The process follows a strict sequence:
- The female turtle emerges from the sea
- She searches for a quiet, undisturbed area above the high tide line
- Using her flippers, she digs a body pit
- A deeper chamber is formed for the eggs
Once ready, she lays between 80 and 180 eggs per nest, depending on the species
After laying, the nest is carefully covered before the turtle returns to the ocean—leaving the eggs to develop independently.
Incubation and Survival
The incubation period typically lasts 45 to 75 days
During this time:
- Sand temperature plays a crucial role
- Warmer sand tends to produce more female hatchlings
- Cooler conditions produce more males
Survival rates are extremely low.
It is estimated that only 1 in 1,000 hatchlings reaches adulthood
Predators, environmental conditions, and disorientation all contribute to this high mortality rate.
The Hatchlings’ Journey
After hatching, baby turtles remain below the surface for several days before emerging.
They instinctively wait for nightfall.
This reduces:
- exposure to predators
- risk of dehydration
Guided by natural light—traditionally the moon reflecting on the ocean—they make their way toward the sea.
This moment is critical.
Artificial light, noise, or human interference can disrupt their direction, significantly lowering their chances of survival.
The “Lost Years”
Once hatchlings enter the ocean, they disappear into what scientists refer to as the “lost years.”
Very little is known about this phase.
Research suggests that young turtles:
- travel vast distances
- drift with ocean currents
- seek refuge in floating seaweed ecosystems
These early years are essential for growth and survival before they return, decades later, to nest again.
Why This Matters in Gili Meno
The beaches and waters around Gili Meno remain one of the few environments where these natural processes can still occur relatively undisturbed.
However, sea turtles are endangered globally.
Their survival depends on:
- protected nesting areas
- reduced coastal disruption
- responsible human interactionTODAY’S TURTLES
