Direct examination and field studies of feeding in amphis-baenians are almost nonexistent, since these animals are so secretive. Therefore, we must rely mainly on indirect studies and on studies of captive animals. Laboratory studies based on dissections of wild-caught animals and examination of stomach contents indicate that bipedids feed primarily on small invertebrates such as termites, beetle larvae, and ants. Bipes biporus fits the pattern of a generalist predator that exploits prey items found both under the soil and on the soil surface covered by objects such as fallen bark or debris.
For bipedids, chemical cues are the most important means used in locating prey. The forked tongue and the Jacobson's organ allow the detection of chemical odors.
