Cyclemys gemeli (Assam leaf turtle)

Cyclemys gemeli is a lesser-known species of Assam leaf turtle, often recognized for its brownish, heavily patterned carapace and distinctive shell shape. This semi-aquatic turtle is primarily found in certain regions of Southeast Asia, where it inhabits freshwater bodies surrounded by dense vegetation.

Scientific Classification

• Kingdom: Animalia
• Phylum: Chordata
• Class: Reptilia
• Order: Testudines
• Family: Geoemydidae
• Genus: Cyclemys
• Species: Cyclemys gemeli

Common Names

• Assam Leaf Turtle

Identification

Description:
Cyclemys gemeli has a slightly domed carapace with a serrated rear edge and a distinctive keel running along the center. The carapace color ranges from dark brown to olive, with darker streaks or patterns, providing excellent camouflage among leaf litter. The plastron is often pale with dark blotches.

Sexual Dimorphism:
Males tend to have a more elongated tail and concave plastron, while females have a flatter plastron and shorter tail.

Native Origin and Distribution

Geographical Range:
This species is predominantly found in Northeast India, particularly in Assam, as well as parts of Myanmar and possibly adjacent regions.

Preferred Habitat

Cyclemys gemeli prefers slow-moving freshwater environments such as ponds, streams, and marshes, often in areas with abundant vegetation where it can forage and find shelter.

Behavior

Feeding Habits:
This omnivorous species feeds on a diet of aquatic plants, small invertebrates, and occasionally fruits that fall into the water. It is primarily crepuscular, being most active during dawn and dusk.

Predators:
Natural predators include birds of prey, large fish, and mammals. Juveniles are particularly vulnerable due to their smaller size.

Reproduction

Breeding Season:
The breeding season typically occurs during the monsoon period, with increased activity as water levels rise.

Reproductive Method:
Females lay small clutches of eggs in sandy or muddy areas near water. The eggs incubate for several months before hatching.

Conservation

Extinction Status:
Cyclemys gemeli is currently listed as ‘Vulnerable’ on the IUCN Red List due to habitat loss and illegal collection for the pet trade.

Threats:
Major threats include habitat destruction from deforestation and water pollution, as well as over-exploitation for the pet trade.

Conservation Measures:
Conservation efforts include habitat protection, stricter enforcement of trade regulations, and breeding programs in captivity.

Economic Importance

While not widely recognized in the global pet trade, Cyclemys gemeli is occasionally sought after by collectors, which has contributed to its declining wild populations.

Interesting Facts

• Cyclemys gemeli has a unique ability to close its shell tightly, which helps protect it from predators.
• The species is named in honor of Dr. Uwe Fritz, a German herpetologist who significantly contributed to the study of turtles.
