Eryx jaculus, the Sand Boa

Geographic range[edit]

Eryx jaculus is found in eastern and south eastern Europe, the Caucasus, the Middle East, and Africa.

Description[edit]

The javelin sand boa may grow to 80 cm (31½ inches) in total length. 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.[3] 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.[4]
