But the most extreme version of such a tongue is that evolved by the placentalmammals including the pangolins (Order Pholidota) the aardvarks (Order Tubulidentata) and South Americanant-eaters (Edentata). In Africa and Asia, there are seven different species of pangolin including the local species called the Cape PangolinManis temminckii a medium-sized creatures 850 mm long with short legs and long stout prehensile tails. The Giant Pangolin (Manis gigantea) is 1,5 metre in length and has a tongue that can extend 400 mm beyond its mouth. The sheath that houses it extends right down the front of the animal's chest and is actually connected with its pelvis. The pangolin has lost all of its teeth and its lower jaw is reduced to two slivers of bone. The ants and termites collected by the mucus on the tongue are swallowed and then mashed by the muscular movements of the stomach which is horny and sometimes contains pebbles to assist in the grinding process.
