Southern River Terrapins

Built For Protection

With an average weight of 38kg, Southern River Terrapins are rather large turtles.

Their high-arched shells, which account for a quarter of their weight, feature buttresses that provide extra support and shield vital organs.

As these turtles mature, their shell bones fuse completely, a process called ankylosis. This strengthens the shell, preventing it from splitting if crushed.

Hatchling To Adult

Hatchlings sport serrated shell edges, spines, and a vertebral ridge, all of which disappear with age.

These changes help the terrapins adapt as they grow, offering protection while they are young, and streamlining their shell as adults.

Colourful Regional Traits

Terrapin colours vary by location. Western Malaysian juveniles and females display grey to greenish shades, while those from the east coast feature a distinctive silver patch behind the eyes. Both have brown or olive carapaces, and their plastrons are dull yellow.

Heat-determined Hatchlings

The gender of terrapin offspring depends on nest temperature, a phenomenon called temperature-dependent sex determination (TSD).

While studies found that temperatures averaging 25.4–33.5ºC  in controlled incubators produced 100% males, eggs in sand nests under natural conditions produced 100% female hatchlings in some years, and a mixture of both sexes in others. Studies continue to refine understanding of TSD in these turtles.

Threats to Survival

Southern River Terrapins face numerous threats, including exploitation for their eggs and flesh, habitat destruction from deforestation, mining, and erosion control.

Nesting areas are rapidly invaded by Lalang grass, reducing viable sites for egg-laying.

Flood-induced silt deposits further exacerbate this issue. Overharvesting of eggs, valued culturally and as traditional medicine, has also significantly impacted populations.

Together, We Protect Wildlife

Rediscovering The Royal Turtle

Rediscovering The Royal Turtle

Once thought extinct, the Southern River Terrapin, or Royal Turtle, was rediscovered in 2001 along the Sre Ambel River.

To secure a future for the species, we partnered with WCS Cambodia, providing funding and support to their conservation efforts, including the construction of the Koh Kong Reptile Conservation Centre (KKRCC).

Conservation measures undertaken also include implementing release and monitoring programmes, and community involvement.

The IUCN Status

CR

Critically Endangered

At extremely high risk of extinction in the wild

Protected River Refuge

Protected River Refuge

These conservation efforts have resulted in more than 147 turtles released back to the wild.

In a boost for the species, the Ministry of Agriculture, Forestry and Fisheries has included the Sre Ambel river system as a protected area for the conservation for the turtles, which ensures greater protection for their habitat and promote nesting along the beaches.

CR

Critically Endangered

At extremely high risk of extinction in the wild

A Historic First

A Historic First

In February 2021, five female turtles that were head-started at the KKRCC laid eggs for the first time under human care in Cambodia, signifying another major conservation milestone for the species.

Nesting activity was also detected in the wild, on sand beaches previously not known to be used for nesting in the last decade.

The IUCN Status

CR

Critically Endangered

At extremely high risk of extinction in the wild

Strengthening Conservation

Strengthening Conservation

Conservation efforts continue with a focus on nest and habitat protection by local communities, enhancements to the KKRCC, mapping micro-habitats, and monitoring released turtles.

Anti-poaching law enforcement, prevention of illegal trade, and outreach with local communities also continues.

The IUCN Status

CR

Critically Endangered

At extremely high risk of extinction in the wild

A Broader Impact

A Broader Impact

Adopting a landscape approach to protecting wildlife and communities, conservation efforts will aid in the transformation of this conservation programme into a broader initiative for this region in Cambodia.

With mangrove habitats and the associated wetlands particularly vulnerable to climate change and being vital to the food security of local communities, this initiative will have a far-reaching impact on both wildlife and human populations living in Koh Kong province.

CR

Critically Endangered
