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 .
Eryx jaculus is found in Eastern Europe and Balkans, [5] [6] the Caucasus, the Middle East, and North-Africa. In September 2014 the snake was rediscovered in Romania near the Danube after being extinct in the nation since 1937, when the last specimen was seen near Cochirleni. [7] 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.
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. [8] 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. [9]
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. [10]
The Boidae, commonly known as boas or boids, are a family of nonvenomous snakes primarily found in the Americas, as well as Africa, Europe, Asia, and some Pacific islands. Boas include some of the world's largest snakes, with the green anaconda of South America being the heaviest and second-longest snake known; in general, adults are medium to large in size, with females usually larger than the males. Six subfamilies comprising 15 genera and 54 species are currently recognized.

The amethystine python, also known as the scrub python or sanca permata in Indonesian, is a species of non-venomous snake in the family Pythonidae. The species is found in Indonesia and Papua New Guinea. Popular among reptile enthusiasts, and noted for its coloration and size, it is one of the largest snakes in the world, as measured either by length or weight, and is the largest native snake in Papua New Guinea. Until 2000, the larger S. kinghorni was generally considered a subspecies of S. amethistina, and this change of classification has still not been universally reflected in literature. Because of this issue, S. amethistina has often been described as the largest snake in Australia, but this is not accurate since under the current classification, this species does not occur in Australia.
