Lumberjacks suffering from cold weather on the job could nail its carcass or skin to a tree to keep warm, while in the process allowing the tree to be felled more easily.

These creatures are found in the Mediterranean countries where many of these legends originated. The Códice Casanatense (), a Portuguese book describing the areas the Portuguese had visited, includes an illustration of the flora and fauna of India. One of the animals shown is a two-headed snake, with one head on each end, much like an amphisbaena. The image is captioned, "two headed snakes of India are harmless". It is possible a sighting of an animal like this was the origin of the amphisbaena.
