Common Names

• Myanmar brown leaf turtle

Identification

Description:
Cyclemys fusca has a medium-sized, slightly domed carapace that ranges in color from dark brown to reddish-brown, resembling a leaf, which provides camouflage in its natural habitat. The plastron is yellowish to light brown, often with dark blotches or streaks. This species has a relatively small head with a sharp beak and distinct yellow to orange stripes on the sides of its neck.

Sexual Dimorphism:
Males tend to have a longer and thicker tail compared to females, which helps in distinguishing the sexes. Females usually have a more rounded carapace, while males might have a slightly concave plastron to aid in mating.

Native Origin and Distribution

Geographical Range:
Cyclemys fusca is primarily found in Myanmar (Burma), Thailand, and parts of Laos. Its distribution is closely associated with slow-moving rivers, streams, and wetlands within these regions.

Preferred Habitat

This species prefers slow-moving freshwater environments such as rivers, streams, and marshes with abundant vegetation. They are often found in shaded areas with access to both land and water, which allows them to bask and forage.

Behavior

Feeding Habits:
Cyclemys fusca is omnivorous, feeding on a variety of aquatic vegetation, fruits, insects, and small invertebrates. They are primarily opportunistic feeders and may also scavenge on carrion.

Predators:
Predators of Cyclemys fusca include larger mammals, birds, and humans. Young turtles and eggs are particularly vulnerable to predation by birds and small mammals.

Reproduction

Breeding Season:
Breeding usually occurs during the rainy season when the water levels are higher, providing more suitable conditions for nesting.

Reproductive Method:
Cyclemys fusca lays eggs in sandy or muddy soil near water bodies. A female typically lays a clutch of 2-4 eggs, which incubate for several months before hatching. Hatchlings are independent from birth and must fend for themselves.

Conservation

Extinction Status:
Cyclemys fusca is currently listed as Near Threatened on the IUCN Red List due to habitat loss and exploitation for the pet trade.

Threats:
Major threats include habitat destruction from agricultural expansion, deforestation, and pollution. Additionally, they are captured for the pet trade and for local consumption.

Conservation Measures:
Efforts to conserve Cyclemys fusca include habitat protection, stricter regulations on trade, and breeding programs in captivity. Conservationists also work on raising awareness among local communities about the importance of preserving this species.

Economic Importance

Cyclemys fusca holds limited economic importance but is sometimes traded in the pet market. Additionally, in some regions, they are harvested for food, which contributes to local economies.

Interesting Facts

• Cyclemys fusca is sometimes referred to as the “leaf turtle” because its carapace’s color and shape mimic a dry leaf, providing excellent camouflage.
• These turtles are known to be quite shy and will quickly retreat into water when disturbed.
• Unlike some other turtles, Cyclemys fusca does not retract its head completely into its shell but rather to the side, a characteristic feature of the genus Cyclemys.
