Snake venom is a highly toxic saliva containing zootoxins that facilitates in the immobilization and digestion of prey. This also provides defense against threats. Snake venom is injected by unique fangs during a bite, whereas some species are also able to spit venom.
Venom in snakes and some lizards is a form of saliva that has been modified into venom over its evolutionary history. In snakes, venom has evolved to kill or subdue prey, as well as to perform other diet-related functions.
Venom is known to be a very poisonous mixture, consisting of a variety of molecules, such as carbohydrates, nucleosides, amino acids, lipids, proteins and peptides.
But researchers have found that humans might someday possess venomous saliva like snakes. Researchers from Okinawa Institute of Science and Technology Graduate University and the Australian... However, that doesn't mean it will never be venomous.
In such texts, venom is defined as a substance produced in glands of snakes, spiders, scorpions, centipedes, wasps, bees, etc., and endowed of means of injecting toxic substances into the aggressor or prey through stings or teeth, which can be solid, grooved or canaliculated (Figure 1).
Venoms kill through the action of at least four major classes of toxin, namely necrotoxins and cytotoxins, which kill cells; neurotoxins, which affect nervous systems; myotoxins, which damage muscles; and haemotoxins, which disrupt blood clotting.
Snake venom is made by organs that evolved from salivary glands. Ordinary saliva contains enzymes to help digest food as you chew it and natural selection has favoured snakes that include ever more toxic enzymes in their saliva.
It's a Natural Painkiller
Did you know your saliva contains a potent painkiller? Human saliva is six times more powerful than morphine thanks to the pain-inhibiting compound opiorphin. Opiorphin is one of the few naturally produced compounds in the human body that extends the body's self-defense mechanism against pain.
Not flammable or combustible.

Whether due to the intensity of the memories returning or the weight of this reunion truly being realized, the symbiote does something it's never done before: It cries tears of joy.
When originally drawn, Eddie was a very big guy compared to Peter Parker. He looked like a pro wrester who took it a bit too far. When he bonded with the symbiote, he was just as big. As different artists took over, Venom got even more huge and cut to emphasize the threat he posed.
Venom and Eddie Brock have one of the biggest "redemption arcs" at Marvel Comics, with both characters operating as full-fledged, brutally violent villains when first introduced, bonding with each other physically and mentally over their shared hatred of Spider-Man.
This results in an animal that can withstand venom with little or no side effect. So far scientists fully understand venom resistance in only four mammals - mongooses, honey badgers, hedgehogs and pigs - as well as several snakes.
DNA exists in venom primarily as a result of cellular content deposition in the lumen of the venom gland following cell death. This cell debris may be ejected along with venom during prey envenomation or during venom extraction [40,41].
Comparisons between CT scans of the fossil and modern reptiles suggest that snakes lost their legs when their ancestors evolved to live and hunt in burrows, habitats in which many snakes still live today. The findings disprove previous theories that snakes lost their legs in order to live in water.
Without saliva, the person is at a very high risk for choking, cavities, and other problems. Therefore, a person without salivary glands will have to use an artificial form of saliva when eating.
In general, gleeking comes from "built up watery saliva" in your sublingual glands, Steven Morgano, DMD, chair of the Department of Restorative Dentistry at the Rutgers School of Dental Medicine, told Health. Then, "pressure on the glands from the tongue [...] causes the saliva to squirt out," added Dr. Morgano.
Saliva contains special enzymes that help digest the starches in your food. An enzyme called amylase breaks down starches (complex carbohydrates) into sugars, which your body can more easily absorb. Saliva also contains an enzyme called lingual lipase, which breaks down fats.
Saliva is 99% water and 1% protein and salts. The normal daily production of saliva varies between 0.5 and 1.5 liters. The whole unstimulated saliva flow rate is approximately 0.3-0.4 ml / min.
The salivary glands produce saliva to lubricate the mouth and throat, begin the process of breaking down food, and make swallowing easier. People normally swallow saliva unconsciously throughout the day. Sometimes, however, a person can accidentally inhale saliva.
The average human produces 25,000 quarts of saliva or spit in a lifetime. That's enough saliva to fill 2 swimming pools!
Venom is a character appearing in American comic books published by Marvel Comics. The character is a sentient alien symbiote with an amorphous, liquid-like form, who survives by bonding with a host, usually human. This dual-life form receives enhanced powers and usually refers to itself as "Venom".
Without a doubt, "The Nativity" arc (by Mike Costa and Mark Bagley) is among Venom's most unusual stories, featuring the alien symbiote becoming "pregnant" (while Eddie Brock was his host) and giving birth to the Sleeper symbiote.
Evolving past Peter Parker, Eddie Brock has become an antihero in mainstream comics. Before he was a phenomenon, Venom was conceived by David Michelinie and Todd MacFarlane in The Amazing Spider-Man #300 (1988).
