ABOUT POISONOUS SNAKES IN THE WORLD

1. DIGITAL ALBUM Submitted By RAKHI R NATURAL SCIENCE CSI COLLEGE OF EDUCATION

2. INTRODUCTION Venomous snakes, the deadliest are species of the suborder Serpentes that are capable of producing venom, which they use for killing prey, for defense, and to assist with digestion of their prey. The poison is typically delivered by injection using hollow or grooved fangs, although some poisonous snakes lack well-developed fangs. Common venomous snakes include the families  Elapidae, Viperidae, Atractaspididae , and some of the   Colubridae . The toxicity of venom is mainly indicated by murine LD 50 , while multiple factors are considered to judge the potential danger to humans. Other important factors for risk assessment include the likelihood that a snake will bite, the quantity of poison delivered with the bite, the efficiency of the delivery mechanism, and the location of a bite on the body of the victim. Snake poison may have both neurotoxic and hemotoxic or cytotoxic  properties. There are about 600 venomous snake species in the world .
