Survey Question	Current Survey Question Should hobbyists ever free handle venomous reptiles with their hands? Recent Surveys Most venomous/toxic Naja species in the world? I have read that the Philippine cobra is the most venomous (mice, 0.2 mg/kg SC with the lowest reported value being 0.14 mg/kg SC) (Brown, 1973). I have recently, come across something in the Indian Journal of Experimental Biology (Vol. 30, (issue 12), pages: 1158-1162, 1992) which stated that the LD50 for Naja oxiana was the most toxic/venomous (mice, 0.18 mg/kg SC and lowest reported value was 0.10 mg/kg). Along with that, the mortality rate for untreated Naja oxiana bites are the highest among all Naja species (70-80%). N.oxiana also produced the lowest known lethal dose (LCLo) of 0.005 mg/kg, the lowest among all cobra species ever recorded, derived from an individual case of poisoning by intracerebroventricular injection. Following N. oxiana and N. philippinensis are N. melanoleuca at 0.225 mg/kg SC and then N. samarensis at 0.23 mg/kg. The water cobras (N. annulata and N. christyi also have very toxic venoms, but no SC values are listed. Only intraperitoneal (IP) values of 0.143 mg/kg for N. annulata and 0.12 mg/kg for N. christyi. IP values tend to be generally lower (more toxic than subcutaneous values, so it would be unfair to compare their IP results to the subcutaneous (SC) results of other Naja species. Then I have heard that (without solid evidence) that Naja nivea is the most venomous, although their murine SC LD50 range anywhere from 0.4 mg/kg (Toxicon, Vol. 5, issue 1, page 47, 1967) to 0.72 mg/kg (Australian venoms and toxins Databse). So which is the most venomous? To me it seems obvious that it is the Caspian or Oxus cobra (Naja oxiana), followed by the Philippine cobra (Naja philippinensis). What do you think or know? I've noticed that the Australian venom and toxin Database seems to have higher LD50 values for all snakes across the board. For example, for the black mamba IP value of 0.01 mg/kg is listed (http://www.sciencedirect.com/science/article/pii/004101018890219X) and Ernst and Zug et al 1996, list a SC value of 0.05 mg/kg for the black mamba. While the Australian venom and toxin Database listed much less toxic LD50's. So there seems to be a lot of variation. 2014-01-23 What's Your Favorite Venomous Snake? 2013-11-13 Deadliest Bite? 2013-09-16 IF the science of self-immunization for a snake envenomation was proven/perfected what is the least benefit(percentage) you would accept before practicing it on yourself? 2013-06-06 how did you learn to keep venomous reptiles? 2013-03-02 View All Survey Questions Have a good idea for a VenomousReptiles.org Survey question?

colletts and rinkhals Posted by Hemachatus94 on May 3, 2010 new new servay please Posted by pictigaster1 on November 5, 2009 Potency Actually vipers it is in the top rankings, but its behind the golden poison arrow frog and the box jelly fish and a few others in potency. Not trying to burst your bubble just a tiny interjection. Posted by varivenom on November 5, 2009 Ethiopian mountain adder, please..... Posted by WilderDude on October 16, 2009 my preferance would be a gaboon viper. i am currently attempting to obtain one myself. Posted by vixx on September 30, 2009 Pseudohaje goldii/nigra top the list of my favorite snakes. I would love to own some one day. Posted by najasuphan on September 27, 2009 cobras if you voted "other" for an australian snake then if you didn't know this all venomous snakes in australia are related to cobras. Posted by vipers on September 26, 2009 Fea's It would be nice to have a fea's viper. I'm a kid and i'm new to this site. But I know alot about snakes. My dream is to own a venomous sea krait. I think it would be really cool,after all it has the most potent venom found in nature! Posted by vipers on September 26, 2009 Not so well known... Mangs are incredible and feas are a one of a kind, but one of my favorites that is not well known and is just amazing is Parias Sumatranus. Check it out if you have never seen them they are screamers! Posted by varivenom on September 21, 2009 Chapel island tiger snake Posted by squigy on September 20, 2009 solid lime green eyelash Tom Crutchfield had a litter of SOLID lime green eyelash tree vipers for sale in 1990 for $80 each. I have never seen any since. They were incredible looking but it was before I had a permit. Nobody else I've talked to has ever seen one. Posted by SHANE on September 19, 2009 Acanthophis pyrrhus Always wanted desert death adders and am unable to find them here in the states. Posted by polystictus on September 18, 2009 :( I am adding a 30 thousand dollar addition to my house. When it is finished, I can resume my hot collection. In the mean time,every hot seems like a treasure to me. Posted by Crotalusssp on September 17, 2009 I'd like to give the Fea's viper a chance. They are a montane species with similar husbandry requirements to Mandarin Ratsnakes; which I've been fortunate enough to do well with with wc specimens.

Posted by reptaquatic on September 16, 2009 Mofugly First, you have a great first name, and your profile is rather spurious. C'mon dude, make this serious, also, change your profile and tell the truth for once. Posted by lanceheads on September 15, 2009 Bitis Parviocula The Ethiopian Mt vipers should be on this list. Posted by Mofugly on September 15, 2009 to own a snake i would never do this! i have a small dog at home... Posted by liliana on September 14, 2009 Jared, You are thinking of A. russeolus.Those and Howardgloydi are in the states. I know 3 people that have them in their collection. Posted by lanceheads on September 14, 2009 Belize Cantil (cant remember ssp right off the top) and A.b.howardgloydi, because there are pretty much none of those guys in the country. That would complete my " I have produced every ssp of agkistrodon" statement. Though I have kept howardgloydi, they never made it to produce. So many snakes, what about Miklos Vipers? Certain VERY rare crotalus (as I recall certain species only have 1 or 2 specimens ever being found). Posted by jared on September 13, 2009 I remember when Tom had captive colletts and no one wanted them they dropped to 125 to sell also captive born coastal tiapans for 125 no one wanted them .I had ugalophis in the early 80s paid nothing for them got bored and gave them away I know exactly what you are saying about prices Randal. Posted by pictigaster1 on September 12, 2009 Something about a mang. Posted by pictigaster1 on September 12, 2009 I picked the taipan of the Fea's simply because I've pretty sure I could keep the taipan alive. I'm a lot less certain about the Fea's and I'd have to shoot myself if I got one and it died... Posted by LarryDFishel on September 12, 2009 Parias mcgregori Posted by FlaSnakeHunter on September 12, 2009 Totally OT, but since I have your attention, did you get my e-mail about bringing my science club to the zoo? If you responded I never got it. Shoot me an e-mail to najak82@hotmail.com. Thanks! Posted by Chance on September 12, 2009 Probably Chance! I DO regret selling off a lot of snakes I should have kept! I just got bored with them though.... Nowadays when I see some of the ridiculous prices on snakes I just shake my head.... Posted by lanceheads on September 12, 2009 Ah Randal you know you just make all us youngins jealous with your trips down memory lane! You've probably traded off or sold snakes I would nearly give my left nut....well nm. Posted by Chance on September 12, 2009 I voted Mang Mt. as I already have a male, I need a female! Collets are neat, I had 2 pairs back in the 90's and traded them for Bushmasters, I liked the Bushmasters better though. Posted by lanceheads on September 12, 2009 I voted 'other' because red bellied blacksnakes aren't on the list. To me, a large, very thick-bodied, live bearing elapid that looks somewhat similar to our eastern indigos would just be phenomenal. Aussie copperheads and collett's snakes would be pretty high on the list as well. Posted by Chance on September 12, 2009 To post a comment, you must be logged in.
