Identification

Description
The Durango Mud Turtle has a compact, oval-shaped carapace that ranges from dark brown to olive, often with subtle patterning. Its plastron is yellowish, featuring a hinge that allows partial closure. Adults typically measure 10–15 cm in shell length.

Sexual Dimorphism
Males are smaller but have longer tails and a concave plastron to facilitate mating, while females have flatter plastrons and larger body sizes for egg carrying.

Native Origin and Distribution

Geographical Range
This species is endemic to Mexico, primarily found in the states of Durango and Chihuahua. It inhabits freshwater systems, including ponds, streams, and temporary pools.

Preferred Habitat

The Durango Mud Turtle prefers slow-moving or stagnant waters with soft, muddy substrates and abundant aquatic vegetation. It is well-adapted to seasonal water fluctuations, often utilizing temporary water bodies.

Behavior

Feeding Habits
Omnivorous by nature, it feeds on small invertebrates, aquatic plants, and carrion. Opportunistic, it adjusts its diet based on availability.

Predators
Predators include larger birds, mammals, and predatory fish. Juveniles are particularly vulnerable due to their smaller size and softer shells.

Reproduction

Breeding Season
Breeding occurs during the rainy season, usually between late spring and early summer, coinciding with increased water availability.

Reproductive Method
Females lay 2–6 eggs in shallow nests near water bodies. The incubation period varies depending on environmental conditions, typically lasting around 90 days.

Conservation

Extinction Status
The Durango Mud Turtle is classified as Data Deficient.

Threats
Major threats include habitat destruction, pollution, and the draining of temporary water bodies for agriculture.

Conservation Measures
Local conservation efforts focus on protecting wetland habitats and raising awareness about the species. Captive breeding programs have also been initiated to support population stability.

Economic Importance

This species plays a role in controlling insect populations and maintaining ecosystem balance. It also attracts interest in the pet trade, though its collection is regulated to prevent overexploitation.

Interesting Facts

The Durango Mud Turtle can survive in ephemeral pools by burying itself in mud during dry periods. Its ability to thrive in challenging environments makes it a fascinating example of adaptation among freshwater turtles.
