Cyclanorbis elegans (Nubian Flapshell Turtle)

Cyclanorbis elegans, commonly known as the Nubian Flapshell Turtle, is a unique species of softshell turtle native to Africa. This species is known for its elegant, flattened carapace and distinctive behavior, making it a fascinating subject of study for herpetologists and turtle enthusiasts alike.

Scientific Classification

• Kingdom: Animalia
• Phylum: Chordata
• Class: Reptilia
• Order: Testudines
• Family: Trionychidae
• Genus: Cyclanorbis
• Species: Cyclanorbis elegans

Common Names

• Nubian Flapshell Turtle

Identification

Description:
Cyclanorbis elegans has a flattened, soft carapace with a leathery texture, which is characteristic of softshell turtles. The carapace is typically olive to brown in color, with a lighter underbelly. The edges of the carapace are flared, creating a “flap” appearance, which is where the common name “flapshell” originates. The turtle has a pointed snout and small, beady eyes, adapted for its aquatic lifestyle.

Sexual Dimorphism:
Females of this species are generally larger than males, with a broader and rounder carapace. Males, on the other hand, have longer tails, which is typical in many turtle species.

Native Origin and Distribution

Geographical Range:
Cyclanorbis elegans is primarily found in the northeastern regions of Africa, particularly in Sudan and South Sudan. It is also reported in parts of Ethiopia and possibly Chad, inhabiting the Nile River system and its tributaries.

Preferred Habitat

Cyclanorbis elegans prefers slow-moving freshwater habitats such as rivers, lakes, and ponds. They are often found buried in the mud or sand at the bottom of these water bodies, where they can easily ambush prey.

Behavior

Feeding Habits:
This species is carnivorous, feeding on a diet of fish, amphibians, aquatic invertebrates, and occasionally carrion. It is an ambush predator, relying on its ability to blend into its environment to capture prey.

Predators:
Natural predators of Cyclanorbis elegans include large fish, birds of prey, and occasionally mammals. However, its softshell and flaps can help it evade capture by slipping away quickly or burying itself in the substrate.

Reproduction

Breeding Season:
The breeding season typically occurs during the rainy season, which varies depending on the region but usually spans from June to September.

Reproductive Method:
Females lay clutches of eggs in sandy banks or other suitable nesting sites near water. The eggs incubate for several months before hatching, and the hatchlings make their way to the water immediately after emerging.

Conservation

Extinction Status:
Cyclanorbis elegans is currently listed as Near Threatened by the IUCN Red List, primarily due to habitat loss and degradation.

Threats:
Major threats to this species include water pollution, habitat destruction due to agriculture and development, and capture for the pet trade.

Conservation Measures:
Conservation efforts for Cyclanorbis elegans include habitat protection, enforcement of trade regulations, and raising awareness about the species’ ecological importance. Some regions have established protected areas where this turtle is known to inhabit.

Economic Importance

Cyclanorbis elegans has limited economic importance but is sometimes captured for the pet trade, which poses a threat to wild populations. It also holds cultural significance in some African communities.

Interesting Facts

• Cyclanorbis elegans is one of the few softshell turtles that can bury itself completely in the mud with only its eyes and nostrils exposed, allowing it to breathe and observe its surroundings while remaining hidden.
• The species’ ability to remain submerged for long periods makes it an excellent ambush predator in its aquatic environment.
