       Sahonachelys is a genus of side-necked turtle that lived in Madagascar during the late Cretaceous.‭ ‬The name Sahonachelys‭ ‬means‭ ‘‬frog turtle‭’‬,‭ ‬a reference to the frog-like appearance of the face.‭ ‬Sahonachelys is thought to have been a specialised suction feeder.‭ ‬This is evidenced by upper and lower jaw surfaces that face each other,‭ ‬a lack of teeth and an enlarged hyoid bone that would allow for wider mouth opening and swallowing.‭ ‬How the suction feeding would work is that the mouth would open very wide,‭ ‬and extremely quickly,‭ ‬resulting in a pressure vacuum within the mouth.‭ ‬If a Sahonachelys did this while a small fish was swimming nearby,‭ ‬that fish would be sucked into its mouth and swallowed whole.
