A creature noted in Biblical scripture and in several medieval bestiaries. It had the foreparts of a lion and the hindquarters of an ant, and its sexual organs faced the wrong way. It is described as so in a medieval text (translated by T.H. White):

It had the face (or fore-part) of a lion and the hinder parts of an ant. If then they engender the ant-lion, they engender a thing of two natures, such that it cannot eat flesh because of the nature of its mother, nor grains because of the nature of its father. It perishes, therefore, because it has no nutriment.
