Gibba Turtle

Overview

A medium-sized side-necked turtle with a high, rounded ('gibbus') dark shell and a broad head. It is an aquatic ambush forager of slow Amazonian waters, feeding on fish and invertebrates as well as fruit. It is relatively widespread but poorly studied.

Classification

The Gibba Turtle belongs to the suborder Pleurodira (side-neck turtles) and the family Chelidae. It is a largely southern-hemisphere family of side-neck turtles that bend the neck sideways rather than retracting it straight back. Its scientific name is Mesoclemmys gibba.

Appearance & Distinguishing Features

They are highly diverse in form, from long-necked snake-necked turtles to short-necked river species, generally with streamlined shells suited to freshwater life.

Habitat & Distribution

They occur across Australia, New Guinea, and South America in rivers, lakes, swamps, and temporary wetlands.

Diet & Feeding

Most are carnivorous or omnivorous, taking insects, fish, crustaceans, and plant matter depending on the species.

Behavior & Conservation

Many lay flexible-shelled eggs and show strong site fidelity to waterways. Several Australian species appear in the pet trade, while some are threatened by habitat loss and introduced predators.

Popularity & Recognition

The long-necked 'snake-neck' turtles are especially recognisable in Australian waterways and aquaria.
