TURTLE CONSERVATION
ON THE GILI ISLANDS
? Turtles are great, you will struggle to find anyone who disagrees.
? They are a major focus for wildlife conservation globally and a large part of our marine conservation
project.
? We here in the Gili Islands are amazingly lucky to be in one of the few, if not the only place on earth
where seeing a turtle in the wild is all but guaranteed.
? This is great as Hawksbill Turtles (Eretmochelys imbricata) are classed as critically endangered on a
global scale and Green Turtles (Chelonia mydas) are endangered, yet they both thrive around the Gili
Islands in Indonesia.
HOW TO TELL THE DIFFERENCE BETWEEN MALE AND
FEMALE TURTLES?
When we study the turtles around the Gili Islands for our Turtle Identification
Program it¡¯s important to know if they are male or female.
But how do you see the difference? Unlike many mammals, turtles have no external
genitalia.
This makes determining their sex much more difficult, but it¡¯s not impossible.
It all comes down to the tail.
A male has a large and thick tail which it uses to secure himself onto the female
during mating.
Another way to determine the difference
between male and female turtles is by
looking at their claws.
Male turtles use their claws during
mating rituals with female turtles.
They also use their claws to fight and to
claim and defend their territory.
Therefore, the claws on the males¡¯ front
legs tend to be longer than the claws of
female turtles.
