Turtles
has appeared on earth for more than 100
million years, to the age of dinosaurs, with
the different that these living dinosaurs
are still surviving through the decades,
despite that environment on earth has been
changing throughout the this period. Studies
reports show that it is possible for a
turtle to live for hundreds years of time,
and this explains why the Chinese society
treats turtles as a symbol of longevity.
Turtles are categorized according to its
physical appearance, behaviors and nesting
site. To your surprise, sex of hatchings is
determined by the temperature of the
surrounding sand, which a female turtle lays
its eggs. A warm nest will result in mostly
female hatchings while males are mostly come
from a cooler nest.
There are seven recognized species of sea
turtle in the world,
which are divided into two families,
Dermochelydae and Cheloniidae.
The only species that is categorized in the
Dermochelydae family is the Leatherback
turtle The rest six species, i.e. Green
turtle, Olive Ridley turtle, Hawksbill
turtle, Loggerhead, Kemp’s Ridley turtle and
Flatback turtle are all belong to the
Cheloniidae family. Among these seven
species, four choose to nest in Malaysia
beaches.
Leatherback turtle
(Dermochelys coriacea)
The name Leatherback turtle
derives from its smooth leathery carapace or
shell. Because of its star fruit-like
leathery soft shell, the locals also call
Leatherback
‘Penyu Belimbing’. An adult Leatherback
can reach a length of 2 meters and weigh up
to 900 kg. It is the largest turtle in the
world.
Although leatherback breeds in the tropics,
they
spend much of their life foraging in very
cold seas. Their body temperature raises
several degrees above that of their
environment. The powerful front flippers of
these turtles enable them to swim for a long
periods of time in the sea. They regularly
dive to depth of over 400 meters with a
recorded maximum depth of 1200 meters.
Leatherbacks are excellent swimmers and
divers, indeed.
In Malaysia, Leatherback nests only in
beaches in Terengganu with Rantau Abang
famous to be the major nesting
concentration.
Green turtle
(Chelonia mydas)
Green turtle or Penyu agar
is called by this name because of its
greenish soft body and jelly like substance.
Unfortunately this special feature has also
made them a very popular food in some
restaurants. Green turtles are carnivorous
in the first few days of their lives and
subsequently become herbivorous. They feed
on seaweeds and algae. An adult Green turtle
can reach the length of 110cm and weight of
150kg. Female Green turtles can lay 140 eggs
per nesting and each takes 50-70 days for
incubation.
To date, Green turtles are among the most
widely spread turtles in Malaysia waters
with the nesting site can be found in Pulau
Redang Pulau Perhentian and Cherating in
east coast, Pantai Remis in west coast of
Peninsular Malaysia and some other beaches
in west Malaysia.
Hawksbill turtle
(Eretmochelys imbricata)
The Hawksbill turtle or Penyu Karah derives
it names from the hawk-like beak. Hawksbill
turtle has hard attractive dark brown shell
or shell with yellow and brown overlapping
scales. This beautiful shell makes Hawksbill
turtle a hunting target for the
tortoise-shell jewelry trading which lead
them to endangering. Adult Hawksbill has a
carapace of 70-90cm and weighted up to
60kg.
Beaches in Pulau Gulisaan of Sabah is the
major nesting site of Hawksbill turtle found
in South East Asian region. However, this
beautiful turtle can also been found in
Pulau Redang of Terengganu.
Olive Ridley turtle
(Lepidochelys olivacea)
Another species, which is found in Malaysia
waters is the Olive Ridley turtle. Olive
Ridley turtle is the smallest of all the
turtle found in the world where an adult
Olive Ridley is only 60-65cm in length and
35-40kg in weight. It is also called Penyu
Lipas by the locals. Just like the name
implies, Olive Ridley turtle has olive-green
or gray colour shell. This turtle feeds
mainly on shrimps, jellyfish, crabs and
snails.
Although nesting of Olive Ridley in Malaysia
is not concentrated and sparse, some nesting
can still be found in Pulau Redang and
beaches in Kelantan.
