Daboia is a monotypic genus[8] created for a venomous viper species, D. russelii, which is found in Asia throughout the Indian subcontinent, much of Southeast Asia, southern China and Taiwan.[1] Within much of its range, this species is easily the most dangerous viperid snake and a major cause of snakebite injury and mortality.[2] It is a member of the big four venomous snakes in India, which are together responsible for nearly all Indian snakebite fatalities.[9] The species was named in honor of Dr. Patrick Russell (1726 - 1805), who had earlier described this animal, and the genus after the Hindi name for it, which means "that lies hid", or "the lurker."[10] Two subspecies are currently recognized, including the nominate subspecies described here.[11]
[edit] Description
Bu yılanlar maksimum 166 cm'ye kadar büyüyebilir. Anakaradaki ortalama uzunluk 120 cm civarındadır, adakilerin ortalaması ise bu ortalamay ulaşamaz.[2] Diğer engerek cinslerine oranla daha ince bir yapısı vardır.[12]
The body is stout, the cross-section of which is rounded to cylindrical. The dorsal scales are strongly keeled; only the lower row is smooth. Mid-body, the dorsal scales number 27-33. The ventral scales number 153-180. The anal plate is not divided. The tail is short -- about 14% of the total body length -- with the paired subcaudals numbering 41-68.[2]
The color pattern consists of a deep yellow, tan or brown ground color, with three series of dark brown spots that run the length of its body. Each of these spots has a black ring around it, the outer border of which is intensified with a rim of white or yellow. The dorsal spots, which usually number 23-30, may grow together, while the side spots may break apart. The head has a pair of distinct dark patches, one on each temple, together with a pinkish, salmon or brownish V or X pattern that forms an apex towards the snout. Behind the eye, there is a dark streak, outlined in white, pink or buff. The venter is white, whitish, yellowish or pinkish, often with an irregular scattering of dark spots.[2]
