Cracked Coco can also be used for protection against food poisoning and venom poisoning. Drinking Cracked Coco while not afflicted with these conditions will confer Food Poisoning Protection and Venom Poisoning Protection.
Some pedantry to chew on here; poisonous and venomous animals differ. Poison refers to toxins distributed in the tissue (ie pufferfish), which can cause harm after ingestion. Venom refers to specific glands and apparatus for deliver of toxin.
Treatment is primarily supportive, but dapsone (an antibiotic known better for leprosy and PJP Pneumonia) 50-200mg/d can be considered for prevention of local effects if used within 48 hours. Analgesics are universally recommended. Signs of systemic envenomation require admission for observation. Antivenin is available in South America, but not commonly in North America.
Spitting cobras protect themselves by shooting jets of venom into the eyes of their attackers. A new study suggests that over the course of several million years, all three groups of spitters independently tailored the chemistry of their toxins in the same way to cause pain to a would-be predator. The work provides a novel example of convergent evolution that "deepens our understanding of this unique system" for delivering venom, says Timothy Jackson, an evolutionary toxinologist at the University of Melbourne.
Like other cobras, spitting cobras will bite attackers in self-defense. Spitting is their signature move, however, and the snakes are crack shots. They can direct a stream of venom into an attacker's face from more than 2 meters away, aiming for the eyes. The behavior is such a formidable defense that it evolved independently three times: in Asian cobras, African cobras, and a cobra cousin called the rinkhals (Hemachatus haemachatus) that lives in southern Africa.
To probe the effects of the extra phospholipase A2 proteins, the scientists dabbed different combinations of toxins from the snakes onto isolated mouse nerves that are sensitive to pain. The more neurons a toxin stimulates, the more pain would result. The researchers determined the three-finger toxins triggered more pain when combined with phospholipase A2 toxins than alone. For instance, when the researchers applied both kinds of toxins from rinkhals venom to mouse nerves, the mix stimulated about twice as many nerve cells as the rinkhals' three-finger toxins alone, they report today in Science.
The study's evolutionary logic makes sense, says toxinologist Stephen Mackessy of the University of Northern Colorado, Greeley, who wasn't connected to the research. Increasing the venom's agony-inducing power would help the snakes ward off predators because "one of the best learning tools is production of pain," he says. But Joe Alcock, an evolutionary medicine researcher at the University of New Mexico, Albuquerque, says it's possible that damaging an attacker's eyes was the driving force to evolve unique chemistry. "If you can blind a predator, that would prevent an attack independent of pain," he says.
Why some cobras began to spray venom rather than just deliver it through bites remains unclear. Some researchers argue the behavior protects the snakes from being stomped on by hoofed mammals. But the side-facing eyes of buffalos, zebras, and other heavy-footed mammals would be hard to hit with a single jet of venom, Casewell notes. Instead, he and his colleagues postulate that early humans motivated the origin of spitting behavior. Our ancestors would have been a menace to the snakes, and they conveniently had forward-facing eyes that would make good targets for a stream of noxious venom.
When you are first exploring your new land in Ancestors: The Humankind Odyssey, the biggest pain can be dealing with the venom and after effects of snake bites. While just drinking water can heal most ailments, there is a quicker, more efficient way solve this problem.
In the wild, cone snails harpoon their prey as it swims by. In the lab, the cone snail has learned to exchange venom for dinner. Here, a snail extends its proboscis and discharges a shot of venom into a latex-topped tube. To see more photos, please view the full photo essay.
In its native state, cone snail venom would obviously not make a great treatment for human ailments. But by unpacking it bit by bit and measuring each component on the molecular level, Marí and his team aim to understand and catalog how each aspect of this poison does its job.
For another study published recently in the Journal of Proteomics, Marí and his team worked on the isolation and characterization of an enzyme in the cone snail venom called Conohyal-P1. They used an ultrahigh-resolution mass spectrometer, one of the most powerful tools available to identify and count proteins in a sample. A similar enzyme is found in both lionfish and bee venoms. Surprisingly, it is also found in many kinds of mammalian sperm, where it helps to weaken cell walls of ovaries and facilitate entry of the sperm and successful reproduction.
In a third paper, published recently in the journal Neuropharmacology, Marí and his team evaluated toxins in the cone snail venom by testing them on the central nervous systems of fruit flies. Although the fruit fly is very different from humans in many ways, its central nervous system can provide a great model for a wide variety of medical studies because the basic structure of cells in fruit fly brains is similar to the structure of cells in human brains. So, if a fruit fly brain cell reacts one way, scientists know a human cell will, too.

The Venom Dart Trap is a trap that fires a venomous dart when triggered via wire. It is a direct upgrade to the Dart Trap, functioning identically except for its increased damage and infliction of Acid Venom rather than Poisoned. It can be crafted with a Dart Trap and Spider Fangs.
Scorpions are arthropods, they have eight legs, two pedipalps, and a tail with a venom-injecting barb. Scorpions have two venom glands that produce venom used in hunting and self defense. Scorpions do not have bones instead they have an exoskeleton made of chitin, which is similar to the shell of a shrimp.
Scorpions are highly effective predators because they possess a unique combination of characteristics that enable them to detect prey (eyes), move quickly and agilely over any terrain in pursuit of prey (4 pairs of clawed legs), and then catch and hold prey (pedipalps and chelae) while injecting venom into the prey (telson) to immobilize or kill it before using the pedipalps and chelae to bring the meal to its mouth.
Scorpion venom is used in moderation, it takes the scorpion a lot of energy to produce. It is used for subduing prey, in self defense and in some species mating. The venom is comprised of a groups of complex molecules called a neurotoxin, these contain proteins consisting of 60-70 crossed linked amino acids. When injected the neurotoxin attacks the nerve cells of the victim causing paralysis and death.
There are more than 45 species of scorpions found in Arizona. Most common in the Phoenix area is the Bark Scorpion (Centruroides exilicauda) which also happens to be the most venomous and only lethal scorpion in Arizona.
Hosted by the Centre for Snakebite Research & Interventions at the Liverpool School of Tropical Medicine, this free online meeting will discuss the the current snake venom lethality murine model, and potential improvements or a new model.
