Is it possible for an animal to use nerve gas as a defense mechanism?

I'm making a book, journal thingy and I may decide to make an animal that uses nerve gas as a "defense mechanism" and by nerve gas I mean like Tabun, Sarin, Soman, or Cyclosarin.

You could possibly use the bombardier beetle as a reference.

Please make it seem atleast a-bit realistic.

  • $\begingroup$ Why do you want/require the gas to affect the nerves specifically rather than some other body-system? $\endgroup$ Sep 18 at 21:57
  • $\begingroup$ @ARogueAnt. You can call me Jello or Jelli or whatever you like, but I would be fine with an aerosolized nerve agent. $\endgroup$

  • $\begingroup$ @I-Stand-With-Palestine im not sure, i just thought it would be a cool idea to add into an organsim. And nerve gas seems quite dangerous considering world powers such as the U.S. and Russia signed a thingy to ban it in war. $\endgroup$

Spitting cobras can shoot liquid neurotoxins.

Cobra venom contains neurotoxins as well as other toxins. It is a defensive mechanism, evolved to hurt the things it hits.

Neurotoxic snake venoms hit many of the same targets as nerve gases. Sarin for example hits acetylcholinesterases.

Multifunctional Toxins in Snake Venoms and Therapeutic Implications: From Pain to Hemorrhage and Necrosis

Three-Finger Toxins (3FTXs) Three-fingers toxins (3FTXs) are non-enzymatic neurotoxins ranging from 58 to 81 residues that contain a three-finger fold structure stabilized by disulfide bridges... For example, α-neurotoxins inhibit muscle acetylcholine receptors (nAChR) (Changeux, 1990), κ-neurotoxins inhibits neuronal AChR (Grant and Chiappinelli, 1985), muscarinic toxins inhibit muscarinic receptors (Marquer et al., 2011), fasciculins inhibit acetylcholinesterase (AChE) (Marchot et al., 1998),...

Snake venom is of course a liquid though it can be sprayed. Usually nerve gases also start as a sprayed liquid that either continues as tiny droplets or volatilizes.

Snake venoms will probably all be proteins and none of the nerve gases listed are. But snake venoms can do a lot of what nerve gases do and additional things besides (check out fasciculins!). So the answer is yes.
