The selection pressure on snake venom is thought to be selecting for functional diversity within the proteins in venom, both within a given species, and across species. [54] In addition to prey physiology, evidence exists that snake venom has evolved in response to the physiology of predators. [13]
Vipera berus - Venom delivery apparatus. Snake venom is a highly toxic saliva [1] containing zootoxins that facilitates in the immobilization and digestion of prey. This also provides defense against threats. Snake venom is usually injected by unique fangs during a bite, though some species are also able to spit venom. [2]

Due to demand for other venoms, it also mass rears and breeds snakes from the Altai, Far East and Central Asian regions, including Halys viper, the short-tailed viper, the Brown mamushi, Vipera libetina turanika and Vipera raddei. Snakes ...
Evidence of early interest in snake venom was prevalent throughout the early 20th century with one of the first big breakthroughs being in the mid-1960s. For example, Halbert Raudonat was one of the first researchers to fractionate Cobra ( Naja nivea ) venom using a sophisticated dialysis and paper chromatography techniques. [ 14 ]
Further study claimed nearly all "non-venomous" snakes produce venom to a certain extent, suggesting a single, and thus far more ancient origin for venom in Serpentes than had been considered until then. [11] [12] As a practical matter, Fry cautioned: [13] Some non-venomous snakes have been previously thought to have only mild 'toxic saliva ...
Rattlesnake venom is a mixture of five to fifteen enzymes, various metal ions, biogenic amines, lipids, free amino acids, proteins, and polypeptides. More specifically, there are three main families of toxins in rattlesnakes: phospholipases A2 (PLA2s), snake venom metalloproteinases (SVMPs), and snake venom serine proteinases (SVSPs). [47]
San Diego toddler Brigland Pfeffer ended up in the pediatric intensive care unit following a rattlesnake bite on his right hand. His parents were hit with a nearly $300,000 bill for his treatment ...
The alcohol helps the venom to dissolve and become non poisonous. [3] Some brands of habushu come with the snake still inside the bottle which is mixed with honey and herbs. [4] [5] There are two methods of inserting the snake into the alcohol. The maker may choose to simply submerge the snake in the alcohol and seal the bottle, thus drowning ...
