Venomous snakes are distinguished from non-venomous species by the presence of a pair of cephalic glands, which produce venom and enlarged Maxillary teeth called fangs. The snake bite venom contains powerful tissue destroying agents and toxins which are mainly directed against nerve and vascular tissue.Tharaka Deshapriya Peirishttp://www.blogger.com/profile/00151023859124050259noreply@blogger.com2tag:blogger.com,1999:blog-2006110583175430914.post-58866332938050862972010-06-10T03:20:00.000-07:002010-06-10T03:22:16.350-07:00Classification of snakes on their venom toxicity<span style="font-weight: bold;">Highly venomous</span><br />Makes the person severely ill(systemic effects), Deadly.<br />Fangs are on the front of the upper jaw<br />Eg:All sea snakes in SL coastal waters, 2 Kraits(Common krait/Magamaruwa/Thel Karawala & Sri Lanka krait/Mudu Karawala), Cobra(Naya), Russell’s viper(Thith Polanga), Saw scaled viper(Weli Polanga) & Hump nosed viper(Polon Thelissa/Kunakatuwa).<br /><br /><span style="font-weight: bold;">Moderately venomous</span><br />Moderate systemic effects, rarely leads to death.<br />Fangs are on the front of the upper jaw<br />Eg: Four species of pit vipers including Green Pit viper (Pala Polanga)<br /><br /><span style="font-weight: bold;">Mildly venomous</span><br />No systemic effects may cause local adverse effects (wound), not deaths.<br />Fangs are on the back of the upper jaw<br />Eg: 12species of Colubridae family snakes. group includes two Ahaetulla species(Vine snake), 5 Boiga species (Mapila in Sinhala/Cat snakes), Dog faced water snake (Kunu diya kaluwa), Blossem krait(Nihaluwa), Ornate flying snake(Malsara), Sri lanka flying snake(Dagara danda) and Glossy marsh snake(Prevostage Diyabariya)<br /><br /><span style="font-weight: bold;">Non venomous</span><br />Majority in Sri Lanka falls in to this category<br />Do not have fangs<br />Eg: Rat snake(Geradiya), Ceylon Wolf snakeTharaka Deshapriya Peirishttp://www.blogger.com/profile/00151023859124050259noreply@blogger.com0
