Every
creature has its own place in this earth and it
is there where it should be. Thus, on October
5, 2007, two Olive Ridley sea turtles were guided
back by the municipal officials, members of the
Bantay Dagat, the fisherman who caught them, several
members of the media and the personnel of the
Department of Environment and Natural Resources,
to the sea where their endangered species were
waiting for them. |
The
members of the Bantay Dagat reported the incident
to Tanauan Mayor Roque Tiu who because he was
in Cebu , requested the Philippine Information
Agency in Region 8 to document the matter and
report it to the Department of Environment and
Natural Resources for proper disposition.
In the meantime, the turtle was led toward the
inland to be placed in the speedboat of the Bantay
Dagat in the meantime. However, it was observed
that the sea turtle kept on turning back towards
the sea. It was as if the sea turtle was looking
for its companion, the members of the Bantay Dagat
noted. |
Mr.
Mariano Donceras, the DENR personnel said that
the olive ridley sea turtles, named for the olive
color of its heart-shaped shell, are considered
as the smallest marine turtles measuring only
2 to 2 ½ feet and weighing 35 to 40 kilos.
He said that the
olive ridley has one of the most extraordinary
nesting habits in the natural world. Large groups
of turtles gather off shore of nesting beaches.
Then, all at once, vast numbers of turtles come
ashore and nest in what is known as an "arribada".
During these arribadas, hundreds to thousands
of females come ashore to lay their eggs. At many
nesting beaches, the nesting density is so high
that previously laid egg clutches are dug up by
other females excavating the nest to lay their
own eggs.
Olive ridleys, he added, reach sexual maturity
around 15 years, a young age compared to some
other sea turtle species. Females nest every year,
once or twice a season, laying clutches of approximately
100 eggs. Incubation takes 50-60 days. After incubation,
hatchlings emerge weighing less than an ounce
(< 28 g) and measuring about 1.5 inches
(3.8 cm). The hatchlings are mostly black
with a greenish hue on the sides.
The olive ridley is mainly a "pelagic"
sea turtle, traveling worldwide, but has been
known to inhabit coastal areas, including bays
and estuaries. Olive ridleys mostly breed annually
and have an annual migration from pelagic foraging,
to coastal breeding and nesting grounds, back
to pelagic foraging. Trans-Pacific ships have
observed olive ridleys over 2,400 miles (4,000 km)
from shore.
Olive ridleys
often migrate great distances between feeding
and breeding grounds. In two separate satellite
telemetry studies, both male and female olive
ridleys leaving the breeding and nesting grounds
off the Pacific coast of Costa Rica migrated out
to the deep waters of the Pacific Ocean . Both
sexes migrated to waters deeper than 9800 ft
(3000 m).
Mr. Donceras put
a tag with the marking of RP 9599 and RP 9600
on the flipper of each of the sea turtles before
they were guided back to the sea where they rightfully
belong and where their group, hopefully awaits
for them.
Mayor Tiu commended the local fisherman for not
killing the turtle which is listed as an endangered
specie. He called on the other fishermen to do
the same, when they are in the same situation,
so as to ensure that the future generation will
also enjoy the bounty of nature that this generation
is now enjoying. (PIA 8) |
