Common Name: Cyclemys gemeli

Scientific Name: Cyclemys gemeli

Habitat:

Cyclemys gemeli is primarily found in the freshwater habitats of Southeast Asia, notably in regions such as Vietnam, Malaysia, and parts of Thailand. This species thrives in slow-moving rivers, swamps, and marshes, where dense aquatic vegetation provides shelter and nesting sites. The typical environment is characterized by warm, humid conditions that support a rich diversity of flora and fauna.

Physical Characteristics:

Cyclemys gemeli is a medium-sized freshwater turtle, with adults measuring between 20 to 30 cm in carapace length. The carapace is generally smooth and oval-shaped, displaying a distinctive pattern of dark brown to black hues with yellow or cream markings. Its limbs are well-adapted for swimming, featuring webbed feet, and its head is relatively small with a pointed snout. Notably, this species possesses a retractable neck, allowing it to hide from predators effectively.

Behavior:

This species exhibits both aquatic and semi-aquatic behaviors. Cyclemys gemeli is primarily diurnal, spending much of its time basking on logs or rocks during daylight hours. It is known for its timid nature, often retreating into the water at the approach of potential threats. Social interactions usually involve basking together and are less frequent during foraging, which occurs more alone. Additionally, it displays a unique ability to navigate through murky waters, which aids significantly in escape from predators.

Diet:

Cyclemys gemeli is predominantly herbivorous, with its diet consisting mainly of aquatic plants, algae, and fruits that fall into the water from surrounding vegetation. Occasionally, it may consume small invertebrates, indicating an opportunistic feeding behavior. The species primarily forages in the shallows, utilizing its keen sense of sight to locate food sources effectively.

Reproduction:

The reproductive habits of Cyclemys gemeli involve seasonal nesting behavior, typically occurring during the rainy season, which provides optimal conditions for the survival of eggs. The female lays clutches of 5 to 15 eggs in sandy or soft detritus areas, with incubation lasting approximately 80 to 90 days. Hatchlings are independent from birth, and there have been observations of maternal care, an interesting behavior in chelonian species.

Conservation Status:

According to the International Union for Conservation of Nature (IUCN), Cyclemys gemeli is currently classified as vulnerable. This status reflects the pressures it faces from habitat loss, pollution, and hunting for the pet trade. Conservation efforts are critical for maintaining the population and protecting their natural habitats.

Interesting Facts:

Cyclemys gemeli is often referred to as the “twin-shell turtle” due to its unique two-toned carapace pattern that varies widely among individuals. This species also plays a pivotal role in its local ecosystem by helping to maintain underwater plant communities through its herbivorous feeding habits.

Role in Ecosystem:

Cyclemys gemeli plays an important role in its ecosystem by contributing to the biological control of aquatic vegetation and acting as prey for larger predators in the food web. Its presence helps to maintain the health of freshwater habitats, supporting various other species that share its environment.
