These animals outlived the dinosaurs and have roamed the earth for more than 200 million years. Reasons for the decline of turtles worldwide include habitat destruction, over-exploitation for pets and food, disease and climate change.
What makes leatherback turtles unique?

Leatherback turtles consume large numbers of jellyfish which helps to keep populations of these marine organisms in check. Marine turtles, including leatherbacks, also provide a vital source of income as a draw for ecotourism in coastal communities, especially in the Coral Triangle.
Are turtle populations decreasing?
Turtle populations are in a state of global decline and are one of the most threatened vertebrate clades, with 52% of all identified species threatened with extinction and 20% listed as critically endangered (Klemens, 2000; Rhodin et al., 2018), and 61% of turtle species listed as Threatened by the IUCN (Rhodin et al..
Why is the population of leatherback sea turtles declining?
Although climate change is most often blamed for declining marine populations, and it does play a role in the disappearance of the leatherbacks, it’s not the most urgent cause of the sea turtle decline. “Perhaps the most insidious impact we are having on turtle populations is on their nesting habitat,” Dr. Todd said.
Are there any leatherback turtles left in Malaysia?
Leatherback nesting in Malaysia has essentially disappeared, declining from about 10,000 nests in 1953 to only one or two nests per year since 2003. The Pacific leatherback turtle populations are most at-risk for extinction as evidenced by ongoing precipitous declines in nesting through their range.
Where are leatherback turtles nesting in the world?
Other suspected leatherback turtle nesting sites are located within the South China Sea region mainly Malaysia. The region was once considered to be the world’s biggest nesting site, but consumption of turtle eggs has led to their steady decline. Leatherback turtles similar to other species of turtle are at their most vulnerable after hatching.
