Big-headed Amazon River Turtle

Overview

A large side-necked turtle with a very broad, heavy head and a dark, domed shell. It inhabits slow rivers and flooded forests of the Amazon basin and is omnivorous, including carrion. It is threatened by hunting and habitat loss.

Classification

The Big-headed Amazon 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 Peltocephalus dumerilianus.

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.
