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?

Expos I can't visit any expos cause I have never come upon one in South Africa.(I hate it) Posted by acjcool on August 4, 2002 Herp Shows I have attended the National Reptile Breeders Expo for the last three years. I also go to a smaller local herp show once a year. The Easter show is kind of difficult for me to attend, family time you know. I really enjoy herp shows (as do all of you) I have yet to go to a show that permits venomous animals, but here in Florida, its not likely to happen any time soon. I work for Mark and Kim Bell, so I may be a vender at the Datona show this year...we will see. :-) Darren Posted by newggtongs on August 3, 2002 kinda partial I go to two Reptile Expos a year, the two San Diego IRBA shows. I think there great, however I guess im a little partial due to the fact that I work for IRBA. Posted by liveprey on August 2, 2002 Expos I am pretty sure to attend Daytona (FL) and Columbia (SC) each year. I have made the last two Jacksonville (FL)(Easter time-frame) Shows. It's a great opportunity to meet and greet the people with whom you converse online. The dinner/meeting of the SHHS at Columbia is a blast.
