In the heart of darkness, life’s throbbing beats. In the
semantic of the night, the possibility of survival. In the blackness of the Ras
Al-Jinz, a quiet beach on the eastern shore of the Arabian Peninsula, the
potential of life is fulfilled, or thwarted. Here, in inkblot holes created in
the sand in slow, slow strokes, the travails of giving birth, the long, invisible
dawn of incubation, the swift process of emergence and the launching of a
career at sea are all realised.
The Green Sea Turtle (chelonia
mydas) has preferred to nest in the sands of just one beach in the
Sultanate of Oman. The fragility of this choice has made it an endangered
species. Human presence over the years has frequently interfered in the precise
motions necessary for the successful breeding of this species. Natural predators
have been adroitly faced off by the turtles themselves, but they really
cannot handle the potentially lethal presence of the one man-made threat- a flash
of light in a moonless night.
Less than a week ago, I was privileged to witness the entire egg laying cycle of the giant Green Sea Turtle on the Ras AI-Jinz beach, a fishing village on the Arabian Sea in the Ras Al-Hadd Turtle Reserve in Eastern Oman. The moonless night was moot to my being able to do so. Turtle watching is a popular tourist activity, but sensitively controlled at the Reserve. Its researchers are very careful about bringing humans close to the turtle mothers, who would really like to get on and get over their labour without being chased by gawkers and paparazzi.
The walk to the beach from the Reserve is a long one. Not easy, as the sand is not very firm. Often, each step you take puts you ankle deep in the sand and you have to drag yourself out of this rather wobbly position and take another step. It hardly helps that there is almost zero visibility other than the small light of the guide’s torch that you follow like a newborn turtle. My efforts slowed me down considerably, allowing me to appreciate the night’s moonlessness. Above me, the Milky Way was arrayed in swathe of sparkle and I could discern interstellar gases in dimly glowing patches around the stars with the naked eye (or with numbered spectacles, as in my case). Watching nebula in our upended galaxy was probably reason enough to be here on this beach. But this was the prelude to the main event.

Our guide and researcher, Kamiz, asked us to wait while an
associate vanished into the night looking for nesting sites. As we fretted, he
showed us other presences- small scorpions that inhabit the beach, or in
absentia, the paw prints of foxes, the chief predators of turtle
eggs. A mommy chelonia mydas, or the Green Sea Turtle is one of the biggest in
the turtle species, reaching four feet from snout to shell. These lumbering
female giants weigh anything between a hundred to a hundred and fifty
kilograms. Most important, each fully grown mum may be between 60 and 70 years
old. That’s twenty years older than I am, and I am no spring chicken. They come
to the Ras Al-Jinz, once or twice a year and, if all the portents are well, lay
upto a hundred eggs at one go.
We all watched in quiet awe, standing in a hushed semicircle
behind the mother, ensuring no inadvertent
distractions. The turtle herself remained stoic and stationary, only the eggs
emerged, one after another. Some light illuminated part of the giant lady’s enormous
shell, oval like a Grecian shield, hued in a deep Chinese jade, with textures
and patterns on her back like a piece of the Jade Hut on the golden beach of
Keelawee from the Lee Falk’s Phantom comics. Then we walked away, backwards,
and the mother was slowly smothered into the sand and negritude.
After laying all her eggs a mother turtle crawls forward by
one body length. This one had done so, her eggs well below the level of the
beach. Here, she was slowly covering them up, shovelling sand behind her over
her potential brood with paddle-like forearms. Once more we took up a position
behind her and watched. There was zen-like calm to her shovelling: one stroke
every once in awhile. One. Two. One. Two. Very mystic. We drew closer, and some
of us got a faceful of grit. We had entered the parabolic catenaries of her
slinging motion. The whole act would last more than two hours. When she was
satisfied, she would move away, leaving a modest mound behind her. She would
then dig up another trough in the sand- a decoy hole to misdirect foxes, crabs
and gulls that would inevitably come out, day or night, seeking succulence in
the sand.
Her annual chore done, the old lady took off sea-wards, and
we followed her, like supplicants, and said our goodbyes as she hit the waves,
which consumed her as she swam away, eastwards in the direction of Bombay. The
Green Sea Turtle never looks back. Once done, she plays no maternal role in the
upbringing of her baby turtles, which fend for themselves after hatching. She
lays a large number of eggs, and very few of those will survive into full grown
adulthood to live their lives out over a century or so. She will repeat this
process decade after decade until she is 80, then stop coming to the Ras
Al-Jinz and live out the rest of her retirement years in the sea.
This is the speed bump in the green sea turtle’s cycle of life. The hatchlings should ideally make their way back to the sea, immediately after breaking out of their eggs. This increases many-fold the possibility of their survival. To hit the surf, they use the ambient light of the galaxy reflected on the waves to find direction. Any other light source, and they scuttle towards it instinctively; and this is potentially lethal. The guardians of the turtle reserve have ensured that the beach remains in total darkness throughout the year, and that no ambient or reflected light from the Reserve reaches the beach.
What are the odds that this cycle could get accomplished
successfully? There are so many obstructions in the way. Even the consistency
of the sand (its chemical properties and temperature will determine the sex of
the babies) is tested by the mother Greens before they decide to lay their eggs
or abort. The Ras Al-Jinz is a safe haven. The Sultanate of Oman’s Ministry of
Environment and Climate Affairs have made significant inroads to alleviate
threats from humans and have tried to preserve the habitat of the turtles in as
pristine a manner as possible, preventing excessive footfalls, littering and
light. The encouragement of sensitive and sustainable tourism probably helps in
this preservation. The Reserve’s commitment to their charges is probably the
only bulwark against the extinction of these lovely giants.
