Just a brief lite tone here.
Ananova presented a quirky some days ago about a Texan King Snake which ate its own tail. I am astonished.
As some of you know, the tail-eating Serpent is an archetypical symbol for different things in many spiritual and religious traditions. All the while, no such behaviour has been observed among reptiles in real life. Self-cannibalism is obviously quite rare in the animal kingdom.
