Thank you very much, b. Malin! Yes, it is fascinating that dangerous venoms can also have medicinal uses. New analytical advances in the fields of venomics, proteomics and transcriptomics have led to the discovery of many new conotoxin sequences in recent years. Seek immediate help if you are experiencing a medical emergency. :), First utrastructural study of the formation of the hypodermic. (2019, November 4). Prialt (or Zoconitide) is a non-narcotic synthetic form of a naturally occurring venom (neurotoxin) found in the Conus Magus snail. Thanks for the education. Faith Reaper from southern USA on January 06, 2014: I always look forward to what you will teach me with your fascinating hubs, and here is another one where I learned a lot. The chemicals are still being explored by researchers and are not yet available as medications. The exception to this rule is their equipment for catching prey, which moves impressively fast. This sounds like an excellent idea, Deb! Cone snails have evolved many 1000s of small, structurally stable venom peptides (conopeptides) for prey capture and defense. Some fish-eating cone snails expand a hood-like structure from their proboscis in order to engulf their prey, as can be seen in the video below. Researchers who are studying conantokins have discovered that they can block seizures in mice. Linda Crampton (author) from British Columbia, Canada on January 05, 2014: Hi, Cynthia. Thanks for sharing. At least some conopeptides are able to relieve pain, which they sometimes do very effectively. Venom used to paralyse their prey: The carnivorous tropical marine cone snail. More than 600 different species of cone snails exist. In addition, researchers are using the neurotoxins in the venom to learn about the functioning of our nervous system. Cone snails have the ability to make hundreds of toxins and deliver a cocktail or mixture of toxins when injecting its venom. Cone snails are now much more popular among scientists than ever before. I especially loved the images of those gorgeous shells. In its native state, cone snail venom would obviously not make a great treatment for human ailments. Linda Crampton (author) from British Columbia, Canada on January 11, 2014: I suspect that I know what type of snail you're talking about, Dianna, since I've written a hub about it! As always I have learned a lot in your corner. Thank you, Alicia :). This is important because ziconotide sometimes produces significant side effects. Derived from cone snail venom, it's used to treat chronic pain. The barbed tooth travels through the proboscis at high speed while still maintaining an attachment to the radular sac. Nature is amazing. The tooth stabs the prey and acts like a hypodermic needle. In addition, anyone taking the medication must be under a doctor’s care. Ziconotide can sometimes be very effective at relieving pain, but its effects are variable.

The shells are so beautiful. Linda Crampton (author) from British Columbia, Canada on February 16, 2018: I have been on Prialt for years! It's great to hear from you again. In addition, this insulin can bind to the human insulin receptor on the membrane of cells. It's interesting that a snail that is so attractive can be both dangerous and useful. How ironic that venom would have medicinal uses! I appreciate your comment and votes. What is especially worrying is that there are almost no conservation efforts for cone snails. Have any problems using the site? To make matters worse, there's no anti-venom for the cone snail's sting. This unique medication is created from a toxin naturally made by the Cone snail (a ω-conotoxin peptide). Craik identified the way small cone snail venom proteins inhibit pain sensors in the Journal of Neuroscience in 2008. The artificial chemical, called ziconotide, has some useful properties. To date, more than 10,000 conotoxin sequences have been discovered. I agree with you - I think we probably have only touched the surface with respect to the health benefits that other creatures can provide. The synthesis and pharmacological characterisation, however, is comparatively more time-consuming. The information below is given for general interest. Conotoxins are bioactive peptides found in the venom that marine cone snails produce for prey capture and defense. Reportedly, ziconotide is not addictive.
