Turtle Tales

Every, year,
between the months of May and September, giant ocean dwelling
turtles come ashore to fulfill the last, crucial stage of
their reproductive cycle: laying their eggs in the sand.
The
most common types of turtles found along, the coasts of
Cancun and the Riviera Maya are the Loggerhead (Caretta
caretta), the Hawksbill (Eretmochelys imbricata)
and the Green turtle (Che-lonia mydas). The Loggerhead
stands out for its reddish-brown coloration; it usually
weighs about 140 kg (300 lbs). The Hawksbill has been hunted
for its translucent carapace, used to produce
tortoiseshell combs and other ornamental articles;
it can weigh anywhere between 14 and 45 kg (30-100 lbs.).
The Green turtle, so-called for its green body fat, usually
weighs between 45 and 90 kg. (100 - 200 lbs).
All of these oversized but beautiful and docile creatures
are in danger of extinction, in spite of all the measures
and laws the Mexican government and other international
organizations have implemented to protect them. Locally,
a great number of individuals, groups and even hotels are
working together to help the turtles.
Francisco C. Cardenas, better known as Don Francisco, Security
Supervisor at a hotel located near Punta Nizuc, in Cancun,
reports that he and his staff play a special role in the
battle to protect the turtles:
“Our staff members are assigned to stay alert during the
season when turtles are expected. When a turtle is spotted,
we make sure she is not disturbed or scared off by curious
onlookers, if she feels threatened, she will head back into
the ocean. We give the turtle the space and privacy needed
to carry out her vital mission.”
At nightfall, the mother turtle crawls ashore seeking a
quiet spot on the beach. Once she feels safe, she begins
to dig a large, fairly deep pit in the dry sand to complete
her task. The egg-laying phase itself takes only about twenty
minutes, but one can see tears running down the turtle’s
face as she groans and whines during the obviously grueling
process.
The eggs are collected as they arrive by a member of Don
Francisco’s team. They are then carefully placed inside
large plastic containers serving as artificial nests. No
sophisticated procedures are involved: the eggs are simply
left alone until they hatch, some 50 days later. Don Francisco
estimates that the Loggerhead lays 160 eggs per nest (sometimes
up to three times per season), while the Hawksbill will
lay 120 and the Green around 90.
After the baby turtles
find their way out of their shells, they are allowed to
rest while they gain the strength needed to begin their
dangerous journey. Many will never make it to adulthood,
but will fall prey to seabirds and other marine creatures.
This is why every effort directed towards supporting their
reproduction is vital for these species' survival.
To increase the odds
of the turtles' survival, a monitored release of the babies
into the ocean takes place; children and adults alike are
invited to actively participate in this process. Once no
scavenging seabirds are seen circling the area, the babies
are carefully hand-placed on the sand. It is awe inspiring
to see the tiny creatures instinctively crawling towards
the water. Last year Don Francisco's team released over
1,000 baby turtles.

Further notes:
We watched a Loggerhead turtle for almost 1/2 hour feeding
on the bottom at Yalku Lagoon this past February (2001).
He was beautiful and so graceful as he surfaced several
times while we watched. We stayed about 3-4 feet away from
him, quietly watching; he wasn’t at all disturbed by our
presence. Later that week I was told there was a turtle
in Soliman Bay, probably a Green by the description. What
an adventure for all of us!
The Si’an Kaan Biosphere Preserve
also implements a monitoring program along the ocean side
in the Preserve and along the Tulum Hotel row. Using volunteers,
they mark the nests, watch for poachers, and release many
baby turtles at night when they are ready. It’s an amazing
sight to observe. Come join us!
