The Amphisbaena is a two-headed creature. One of it's heads holds the other at the neck, bending the creature into a circle. It moves by rolling itself like a hoop, and can go in any direction in this way. The Amphisbaena is the first creature to come out of hibernation in the spring. It has very poor eyesight and likes to eat ants.
According to the Roman writer Pliny, the skin of the Amphisbaena can be taken as a remedy for cold shivers.
The word Amphisbaena means "to go both ways" in Greek.
