Magdalena River Turtle
Podocnemis lewyanaAlso known as Rio Magdalena River Turtle, Magdalena Sideneck Turtle
Magdalena River turtles spend most of their lives basking on sandbars and swimming through deep, slow-moving river currents across northern Colombia. Females undertake seasonal migrations during low-water periods to lay clutches of parchment-shelled eggs in sunny bank deposits. Severe habitat alteration from hydroelectric dams and intense pressure from harvesting have caused dramatic population declines throughout their range.

Interaction riskLow
- Low
- Moderate
- High
- Very high
- Why interaction risk is low
- Capable of delivering a painful bite with powerful jaws; observe safely from the riverbank without handling.
- Why it is dangerous
- Strong, sharp jaw margins designed for tough vegetation can inflict severe bites if the animal is restrained.
- How to recognize a risky encounter
- Look for a broad, smooth brownish shell and a side-folding neck characteristic of Podocnemididae.
- What to do
- Do not attempt to touch or catch wild river turtles; view them from a respectful distance.
- What to notice
- Recognizable by its olive to brown shell and endemic presence in Colombian lowland river basins.
- Support conservation
- Maintain a quiet distance along riverbanks and never disturb sandy nesting grounds.
Responsible observation
- Spotting Basking Sites: Scan exposed sandbars and fallen logs during sunny morning hours.
- Nesting Etiquette: Avoid sandbars during dry-season nesting periods to prevent nest damage.
- Boat Caution: Keep riverboat speeds slow in known habitats to avoid propeller strikes.
