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.

Just how nuch time and money do our elected represenatives plan to spend on the issue of pythons in the Everglades? Don't the morons understand that we have more pressing problems we need to address?
Is pythons in the Everglades a more serious problem than crime in the streets?
According to one article I read recently, there are more "pet" tigers in the U.S. than in all the wilds of southeast Asia.
Don't our politicians have better things to do with their time than worry about snakes in the Everglades?

This is nothing new.They don't come for your freedoms all at once,they take it a little bit at a time. You can bet that a federal ban on venomous snakes is coming soon. My opinion of politics and politicians has always been low,so this doesn't change my opinion.This proposed ban will do nothing to adress the problem in the everglades. This is just big government at its finist,and this is just the tip of the iceburg,I'm sure there is more to come.

i don't have much of a say in the oppinion (I'm a cunuck)(canuck+ canadian you know the cold place right above you) but i think it is almost a good thing because off all the irrisponsible keepers who buy them as a neonate and flush em one they grow.

Same as it ever was...

Nope, nothing new about fear-mongering activists, politicians jumping on the band wagon or citizens willing to ban anything that doesn't interest them personally.

Politicians will do whatever they think will keep them in office.If enough people would let them know that reptile bans/regulations would cost them their seat, they'd never pass. As long as the majority of the voters think that these bans are for the good of the people, it makes it look like the politicians "care" about them. The blind leading the blind. In answer to the question, no, it hasn't changed my opinion of politics. Same old, same old.
