Morphologically this species can be identified easily in most of the parts of range (for most of the parts its the only species of blind Snake) by checking glossy and cylindrical body of brown to black color, rounded snout which bears four vertical sutures, very short tail with a single spine.
Indotyphlops braminus is distinguished from all other members of the Typhlopidae by the combination of: 1) the inferior nasal suture in contact with the preocular shield 2) the superior nasal suture extending to the dorsal of snout to contact the rostral and 3) greater than 270 middorsal scales. Alternatively, it is separable from all Serpentes in being a unisexual, obligate parthenogen and having point contact of the ventral scales, each of which has a black spot anteriorly.
Length: Smallest known length- 3.5mm. Sexually matured minimum known size- 95mm. Average length- 120 mm (12cm.). Maximum length- Approximately 200 mm (20cm.). Weight: The lightest and heaviest recorded specimens of Ramphotyphlops braminus are from Thailand, 0.05 gm and 1.87 gm respectively. In a study mean body weight for 355 live or freshly killed specimens was 0.23 gm for juveniles while 0.74 gm for adults.
Body thin (not thicker than a gel pen refill in general comparison), small, cylindrical and covered with very small and subequal scales. Head short, very slightly or not broader than neck, very slightly depressed but can be best observed from lateral view; snout rounded. Eyes very small and in the form of black dot on slightly lower side of the top of head. Tongue color white, with a pair of lateral papillae near base of bifurcation. In light and moderately dark specimens each scale is marked with triangular apical spot on front which occupies ¼-1/2th part of respective scale. Color ranges from uniform glossy black, wide range of brown color, reddish-brown etc. on upper side which usually become more or less faint underside; new born individuals always have jet black or glossy black color including snout and other parts. In dark specimens this difference of underside lighter than upper may not be noticed. In deserts, semi-deserts of its range color is much lighter (pinkish) while in regions having low temperature range or during winters it shows majority of dark coloration. Snout color lighter with whitish sutures, in dark individuals head sutures produce contrast and can be clearly seen. Lower of snout, chin, cloacal region, tip of tail (which ends with a spine) usually much lighter and often of white color.
