A member of the Chelidae family of aquatic turtles found primarily in Australia and South America, characterized by side-necked or pleurodire movement.
From Greek 'chelone' (turtle) plus the Latin suffix '-idae' used in biological taxonomy. The Greek root refers to the mythological turtle, and the suffix denotes a family classification in zoological nomenclature.
These turtles have an unusual defensive strategy—instead of pulling their heads straight in, they fold their necks sideways under their shells, which is why they're sometimes called 'side-neck' turtles. This ancient design has remained largely unchanged for over 200 million years!
