LOL, "Night Of The Living Thread".
Whoever compared FWc's to C. horridus needs to seriously rethink that statement. Unless they are comparing some other detail regarding a bite that I am missing. Just how on earth does one begin to compare FWC venom and Timber venom, or the effectiveness of these VERY different delivery systems?
And whoever stated that they have read of a fatality to FWC venom, please post the link. I am very interested in learning who came up with that story.
Take Care,

This was a comparison of the relative toxicity of the venom. Which rather than making it potent, makes it relatively piss weak. Typical rattlesnake venom takes an estimated 100 mg or more to cause a fatality, obviously considerably more than an elapid. SO Hydrodynastes having venom of this relative potency, puts it on the mild end of the toxicity spectrum. This is consistent with the venom composition being made up of many of the same toxin types as vipers (kallikrein enzymes and metalloproteases being particularly rich).
In contrast, colubrids such as Boiga and Telescopus have much more potent venoms, reflective of the chemical composition being quite similar to elapid venoms (particularly rich in three-finger toxins).
This is of course only one variable in a very complex equation, in which relative efficacy of delivery and venom quantity are two other significant influences. With the exception of some colubrids such as boomslangs which have very efficient delivery systems, light gardening gloves and long sleeve shirts are sufficient protection against envenomation by rear-fanged species.

Dr. Fry, that is what I figured. It just seems so remote to me to even compare such venoms.
Maybe it is just me, but just by general toxicity, and the variation in delivery systems, it seems a very distant and irregular comparison to me.
Actually, I just noticed the boomslang in your "Favorite Species" category on your profile. I have always been a bit intrigued by the boomslangs. I owned one for a very short time (3 months maybe), but he was a very interesting critter.
I would be very interested in hearing your personal thoughts on them. I would message you on FaceBook, and have thought of doing so before. But, I have refrained from it, because I know that there are thousands of questions that I would like to ask you, LOL.
Thank you for the help with the Nerodia question.
The Colubrid venom research is very interesting to me.
Take Care,
-John Mendrola.

I think he is talking about the African water cobra, which are highly venomous. Myself and my colleague have been envenomed by false water cobras and the only effects were a mild headache, which i'm sure was psychosematic.

I believe that the original question was about the South American false water cobra, and I didn't men to exaggerate the dangerousness of these snakes, only to point out to the individual who made the original question that it's more than a short step from keeping such placid species as ball pythons or rainbow boas to Hydronastes. Rear fangs and venom aside, they are just very active and nervous snakes and quite a handful for a novice keeper.
