Magdalena River Turtle

Overview

A large side-necked turtle endemic to the Magdalena river basin of Colombia, with a dark, flattened shell and a broad head. It is largely herbivorous, feeding on aquatic plants and fallen fruit. It is critically endangered from egg harvesting, hunting, and river modification.

Classification

The Magdalena River Turtle belongs to the suborder Pleurodira (side-neck turtles) and the family Podocnemididae. It is a family of large South American side-neck river turtles, the only pleurodires native to the Americas. Its scientific name is Podocnemis lewyana.

Appearance & Distinguishing Features

They have broad, smooth shells and robust limbs, with the giant South American river turtle among the largest freshwater turtles in the world.

Habitat & Distribution

They inhabit the major river basins of South America — especially the Amazon and Orinoco — in rivers, floodplains, and lakes.

Diet & Feeding

Most are omnivorous or herbivorous as adults, taking fruits, seeds, and aquatic vegetation along with some animal matter.

Behavior & Conservation

Females gather in large nesting aggregations on sandy riverbanks, a behaviour long targeted by harvesters. Several species are listed under CITES and are conservation priorities.

Popularity & Recognition

The giant river turtle is a cultural and ecological keystone of the Amazon, central to both local tradition and conservation efforts.
