Eryx jaculus, known commonly as the javelin sand boa, is a species of snake in the Boidae family. [3] [4] It is the type species of the genus Eryx .
Scientists from Razi university write describe it as “brownish-green or gray, with darker blotches, belly white or yellowish, uniform or speckled darker” (Rhadi,Pouyani et al.)
The species is rather uniform in body thinkness, a trait commonly seen in the Eryx genus.
Eryx jaculus is found in Eastern Europe and Balkans, [5] [6] the Caucasus, the Middle East, and North-Africa [7] . In September 2014 the snake was rediscovered in Romania near the Danube after being extinct in the country since 1937, when the last specimen was seen near Cochirleni. [8] In late 2015 the snake was rediscovered near Licata on the south coast of Sicily after not having been officially recorded in Italy for eighty years[ citation needed ]. The snake has also been found in India, Sri Lanka and Mongolia [ citation needed ]. The Mongolian name of the snake is “batra” which can be translated to "father"[ citation needed ]. Their diet consists of lizards, small mammals and other snake species[ citation needed ].
The javelin sand boa may grow to 80 cm (31+1⁄2 in) in total length (including tail). Coloring varies greatly. Dorsally, it may be grayish, tan, brownish, or reddish, with darker blotches or bars in an irregular network. It usually has a dark streak from the eye to the corner of the mouth. Ventrally it is whitish or yellowish. It is heavy-bodied and has a short blunt tail. The ventrals are very narrow, less than ⅓ of the width of the body. [9] The rostral is large and broad with an angular horizontal edge. The eye is separated from the labials by one or two rows of small scales. There are 10-14 upper labials. The dorsal scales are in 40-50 rows, smooth anteriorly, but weakly keeled posteriorly. There are 165-200 ventrals, and 15-34 subcaudals. [10] They are relatively built simple with small scales just like other snakes in their family. The snake has been very unstudied. In May and September 2014 scientists in Iraq with the help of locals were locating the snake. Schleich and Szyndlar write, “We want to know more about these snakes to find out about their past distribution of these snakes in the west” (Schleich, Szyndlar 234). All snakes under the Eryx Genus have the same 3 scales pointed in different directions just like a star. You can identify it by its small eyes and neck. The whole head is covered with small scales. A very good description comes from the scientist at the university in Iran, “A green brown, or gray snake dorsally with darker blotches, and with a spotted yellowish or white belly; no neck, a stumpy tail, small plates on the head, a vertical pupil, posterior dorsals slightly keeled, ventrals narrow” (Rhadi,Pouyani et al.).
The javelin sand boa was one of a number species of snake used by ancient Greeks as projectiles during naval battles in order to cause fear and confusion on enemy vessels. Its habitat spread from its original location to the areas conquered and settled by the Greeks. [11]
