Snakes have evolved to produce and deliver some of the most toxic substances on earth. It stands to reason that they would need to develop some form of resistance or immunity to their own venom, especially so when the primary purpose of their venom is to incapacitate prey. It would be poin...
Leopard gecko (Eublepharis macularius): Credit: Adam Hargreaves The venom of advanced snakes is a mixture of dozens of different proteins and is an example of an evolutionary innovation – a novel trait that has arisen in a particular animal group and which has contributed to their success. U...

How do snakes produce venom? What is the Deadliest Snake in the United States Does sulfur or lime keep snakes away? Do mothballs help repel snakes? What is a snake’s natural diet, and how does it obtain its food? Do snakes drink water?
To determine how these venoms evolved, a team led by Noah Dowell and Sean Carroll at the University of Wisconsin–Madison analysed the genomes of the three rattlesnakes and more distantly related snakes. Comparisons of venom genes suggest that the last common ancestor of rattlesnakes, which lived...
but not all species have evolved the metabolism to produce it or the mechanism to deliver it. Those that haven't sometimes mimic the appearance and behavior of their venomous counterparts to take advantage of the benefits of a venom system without actually having one. The bullsnake (Pituophis ...
They can inject venom into their prey. They can produce silk. They have a pair of small appendages on the head, called pedipalps. Their bodies are divided into two sections, the cephalothorax and the abdomen, joined by the thin pedicel. The cephalothorax -- a fused head and thorax -...
We'll take a look at the different types of bee and how they use the substances their bodies produce in the next section. Bee Venom A bee's venom contains several substances that destroy cells. These include peptides and enzymes that break through and destroy the layer of fats lining each...
Many snakes, particularly from theElapidae,ViperidaeandAtractaspididaefamilies, deliver toxic venom from their fangs as both a protective mechanism and to help them catch their prey. Similarly, iguanas (Iguaninae) have a weak, mostly harmless, venom that can cause serious damage in the rare eve...
