Cerastes
Cerastes
Large and extremely flexible serpent with horns
is a creature of Greek legend, a serpent that is incredibly flexible—so much so that it is said to have no spine. Cerastae can have either two large ram-like horns or four pairs of smaller horns.
The Cerastes, “horned”, is one of the many snakes born from the blood of Medusa in the Libyan desert. It receives a passing mention in Lucan’s catalogue of snakes. Another cerastes mentioned by Theophrastus and Pliny, in the form of a two-horned herbivorous worm, is obviously a caterpillar.
No more than 2 cubits (about a meter) long, the cerastes is sandy-colored and white, with red streaks across its back. The skin is very soft and stretchable. On the head are two, four, or eight horns, described as worm-like or ram-like. The fangs are like those of a viper and are not crooked. Instead of a backbone, a cerastes has a cartilaginous spine, making it the most flexible of all snakes.
The horns of a cerastes have two documented functions. They are used as lures to attract birds, with the snake buried under the sand with only the horns protruding.
