least dangerous venomous snake?

This is a tough question to answer. It turns out that most snakes are venomous in some way or another to humans, but their effects are often so mild that it is generally unnoticeable. Thus, there is a gradient between non-dangerous and dangerous, depending on how you define "dangerous." Does dangerous mean always life-threatening, or potential for tissue damage?

Willingness to bite is also another factor contributing to the dangerousness of snakes. For example, sea snakes have extremely potent venom, however they are generally not as aggressive as other venomous snakes. Probability of an encounter is yet another factor.

If you want a specific example, we could discuss species of snakes in the United States. Of snakes that are classically considered venomous (vipers, cobras and relatives), I would say the copperhead has the least potent venom, though bites often result in extensive tissue damage. However, there are other species considered mildly venomous to humans, such as the black striped snake (Coniophanes imperialis), the cat-eyed snake (Leptodeira septentrionalis) the lyre snake (Trimorphodon biscutatus) and the western hognose snake (Heterodon nasicus). Bites from these species can have some effect, but I have never heard of any permanent damage as a result.

it is difficult to say. There are some people who are allergic to the secretions of some snakes that are considered harmless by most people, yet the allergic response can mimic symptoms of envenomation, leading some people to claim that these snakes are in fact venomous. Kenneth Kardong of Washington State University rightfully pointed out that even though the Duvernony's gland found in most harmless snakes may have secretions that are toxic to humans if these chemicals are injected, their toxic properties may by an incidental byproduct to the actual function of these secretions, which may be digestion and/or lubrication of the prey for swallowing by the snakes that have these secretions. Since these chemicals are not used in self defense or for subduing prey, these secretions cannot be considered venom.

Excluding these harmless colubrid snakes, we are left with some rear fanged colubrid snakes such as the boomslang, which is deadly, and the vipers and elapids as true venomous snakes. Among vipers, the copperhead and cottonmouth appear to be the least dangerous, with the copperhead even less dangerous than the cottonmouth.

Nevertheless, the copperhead's venom can damage tissue and leave permanent scars and disfigurement, even if the bite is almost never fatal. A few known deaths have also been reported, and these include bites from multiple snakes.

IF you MUST handle a hot snake - start by getting trained. Plenty of zoos have herpetology groups . and after months of good training one can open that door of opportunity. Follow ALL safety protocols to the letter, do NOT deviate at all, regardless of your instinct, and if you're ever in doubt, WAIT ... DON'T.

After you've been well trained ,supervised, milked enough snakes venom and have the source to purchase CroFab then your trainer will give you a book. This is NOT a book available on Amazon, it's passed from handler to handler. Read every letter of that book - memorize it - and follow it to the letter.

Now that had to be said ....

To answer the question ...... the hognose is part of the viper family, but the poison is relatively mild to humans, but they do tend to have strong jaws (think eastern water snake strong) . Copperhead poison is a bit more necrotizing to the skin, but the big problem with copperheads is that they make repeated bites, and young ones have less control of their venom muscle, so envenomization is common on multiple bites i.e. each site you'll see swelling after about 6-10 min and each one has the intensity of 4 yellow-jacket stings.

Cottonmouths dish out a bit more hemotoxic venom, but they tend to only bite once. Can't say I've ever been bit, but I've had two friends get a wet bite, and I must say the swelling looks like something from a horror movie. Timber rattlers are almost identical poison but they are reclusive and tend to avoid contact ( advise .... JUST DON'T HANDLE THEM - they want to be left alone - so please oblige)

Eastern diamondback is the strongest venom of the vipers found in NAmerica - their size, hollow fang cavity, and disposition generally one wont get a "dry" bite from them (i.e. no venom).

Now I should mention there is one Elapid in North America. In all my life I've seen only one in the wild. It's called a coral snake (remember the rhyme "Red Touch Yellow") is often confused with the scarlet king-snake or milksnakes . Their poison is very different. They are usually nocturnal , they flee from activity, and are reclusive and hard to find. Story has it their bite is more of a "chewing/grinding" bite, as the venom comes out slowly through the fangs. The fangs are small and short so a bite penetrating through denim or leather is extremely

unlikely.

If they were to get a bite into bare skin, the bite laceration will not hurt as much as normal bites. The neurotoxin in cobra bites aren't nearly as painful as vipers (so so I'm told, i've never been bit). Problem is ... the right dose of neurotoxin gets to muscles and induces a comatose phase (i.e. stop breathing, heartbeat) which takes 6-18 hours to wear off. Problem is ... the Pfizer company doesn't find it profitable to make Coralmyn (the elapid venom antidote) so .... unless you're near an ER in Dade co FL or Cameron Co TX it's unlikely the local hospital will actually have that in their pharmacy. Might consider calling the local zoo while in route to the hospital.

In fact ..... there's only about 20 coral snake bites per year in America, so if you are lucky enough to see one, stay 3 feet away and use a camera to capture the moment .... not your hand.

Garter Snakes are pretty harmless Rough Green Snakes tend to be a little more mild tempered though. Racers are also not dangerous, but they are likely a little too spunky and ill tempered for your tastes.
