Amphisbaena
The amphisbaena (/ˌæmfɪsˈbɛɪnə/, /ˌæmfɪsˈbaɪnə/, or /ˌæmfɪsˈbiːnə/, plural: amphisbaenae; Ancient Greek: ἀμφίσβαινα) is a mythological, ant-eating serpent with a head at each end. The name of the creature is alternatively written amphisbaina, amphisbene, amphisboena, amphisbona, amphista, amfivena, amphivena, or anphivena, and is also known as the "Mother of Ants". Its name comes from the Greek words amphis, meaning "both ways", and bainein, meaning "to go".
