Overview:
Geoffroy’s Side-Neck Turtle (Phrynops geoffroanus) is a unique and slender freshwater turtle native to South America, particularly found in Brazil, Paraguay, and Argentina. Named after French naturalist Étienne Geoffroy Saint-Hilaire, this species is known for its long, flexible neck that tucks sideways under its shell. With its smooth oval shell and expressive features, Geoffroy’s Side-Neck is a fascinating addition to any aquatic turtle collection and does well in a warm, well-filtered tank with plenty of swimming space.
