Elapids or snakes with neurotoxic venom can be found in Asia, Australia, Africa, and North and South America. Gaboon Vipers have very large venom glands and have the highest venom yield and can inject anywhere from 200-1000mg in a single bite. When neurotoxic venom is introduced into the body, it quickly causes problems. As long as a venomous snake breaks the skin, it is able to inject venom if it wants to. Fry thinks that both the effectiveness of antivenoms and our ability to care for patients will be greatly improved if we get a better understanding of the idiosyncracies of venom in local snakes. The X-ray crystal structure of RSL, in complex with lactose and thiodigalactoside, at 2.2 and 2.3 A resolution, respectively, reveals a decameric protein composed of two 5-fold symmetric pentamers arranged in a staggered, back-to-back orientation. Most snakes with hemotoxic venom are vipers and are in the family Viperidae. In one, you’ll find a rattler with purely haemotoxic (blood-destroying) venom.

Rattlesnake venom can be characterized by the presence (Type A) or absence (Type B) of a type of neurotoxic phospholipase A 2 (PLA 2 ), such as Mojave toxin, that increases venom toxicity. Some venomous snakes are viviparous and actually give live birth. There are a few reports of recreational use of snake venom to experience a “high” – don’t try this at home.
