What back-fanged snakes pack serious venom?

Question

Ok, we all know that Elapids are the most toxic, followed by Viperidae.

What most people do not know is that back fanged colubrids can be deadly. This is a primitive venom injection system that usually requires knawing on a prey item to inject.

I know that Boomslangs, African Twig Snakes, and Mangrove snakes are dangerous. The Boomslang and African Twig Snake have been known to cause human fatality if the bite is not treated. Most people do not consider a bite from a back-fanged colubrid dangerous and those who do not pay for it.

I was bitten by a Mangrove and can testify that I did not feel very well for awhile.

What are the other back-fanged colubrids that pack a potent venom whallop? I am talking about colubrids that can harm or even kill an adult human in good health?

Coral snakes are elapidae. I think they are the only American elapidae. I have read that they are front fanged like all elapidae.

Here is a quick and easy googling on them that verifies front fangs:

I know that most Colubrids are, indeed, harmless. Most of the back fanged colubrids (not the majority of Colubrids) that DO have venom do not have anything potent enough to harm a human.

I am just wondering which ARE actually dangerous to humans. The only ones I know of are the two I listed.

Oh that was just a quick google. I know there are much better sites out there about Corals.

Answer 1

Sorry this is just a jumble of types but I left the links for further research :

Montpellier snake
US Hognosed snake and Lyre snakes are rear fanged and venomous
However, if such a snake can chew the fingers or skin of a human being for couple of times the amount of venom that will be poured in the process might be fatal. Example of such snakes in Bangladesh are sutanali sap Ahaetula species; Phanimanosha, Boiga species; Dog-faced Water Snake (jol boda), Cerberus rhynchops; kalnagini Chrysopelea ornata; pani sap, Enhydris species; White-bellied Mangrove Snake (sundari sap), Fordonia leucobalia; Glossy Marsh Snake Gerardia prevostiana; and Red-necked Keelback (lal dora sap), Rhabdophis subminiata.Many colubrids have oral glands, Duvernoy’s glands and others that contain toxic compounds. Most do not have the means to deliver these secretions, but toad-eaters, especially Heterodon species (American hognoses), have long teeth that can.
There have been unpleasant symptoms recorded from bites from Heterodon, Leioheterodon (Madagascan hognoses, especially L. modestus, the brown hognose), Hydrodynastes (false water cobra) and others (even Thamnophis garter snakes in some sensitive souls). Most reactions are limited to localized pain and swelling but should not be ignored.

Answer 2

Not all snakes of the family Colubridae are poisonous. This is a huge family that includes harmless snakes like the king snakes and some garter snakes. It also includes Elapinae. This subfamily contains some of the most poisonous snakes, such as the American coral snakes, cobras, and mambas. The American coral snakes are back-fanged elapines. They are deadly. They usually have color patterns that can confuse them with scarlet snakes or king snakes, which are harmless.

Answer 3

The opposite of deadly, the venom stealthy trouser snake can actually cause the creation of additional human beings.

Answer 4

the biggest danger from back fanged snakes is the bacteria and other germs and viruses you can get from them not the venom.

Answer 5

The coral snake.
