Malagasy Blonde Hognose (Leioheterodon modestus)

Neotropical Hognose Group or False Yarara (Lystrophis dorbignyi) [4 subspecies]

Tri color Hognose (Lystrophis semicinctus)
Matogrossen Hognose (Lystrophis matogrossensis)
False Coral Hognose (Lystrophis pulcher)
False Coral Snake (Lystrophis histricus)
False Coral Snake (Lystrophis nattereri)

Southern Hognose (Heterodon simus)

May I ask why you have Hyrdodynastes gigas on there?

Also where/how are you classifying them?

Ring necked snakes are also rear fanged as well as the coral snake

EDIT

I meant to ask why they were listed in the Dangerous section

I think all rear fanged snakes are considered venomous. However, not all are considered medically relevant in their effect on humans. Is that correct?

I believe a lot of snakes are considered venomous, like you said, which is relevant to humans is a different story.

I have been looking for links to research done that compares the venom of said species up top.

If your looking for research on venomous.... go to one of the leading researches in the field.

Check out www.venomdoc.com Dr. Fry is very good at what he does.

may i know the reason that mangrove snake is consider dangerous??

so far the list is very sketchy to me where and how have you come to the conclution that fwc are dangerous. false water cobras arnt dangerous and ive seen a southern hog bite jack someone up way worse than a fwc bite so all of that list is kinda screwy to me and the mangroves arnt dangerous eather as for more species that are rear fanged one that comes to mind that isnt on the list is the cribo species yellow tail black tail etc.

Can I also point out that 'dangerous' implies a level of study we have not yet achieved. Any rear-fang can be deadly if you happen to be allergic to the venom. Different people react differently to different venoms. Quite a few species may actually have venom that is adverse to humans, but the snake is so small it is almost impossible for them to inject something as large as a human and the amount of venom in a bite from a tiny species can be fairly irrelevant (such as in the hypisglena species). Thus the problems in enacting reasonable legislation......

I'm curious as well..

I'm with the other guys on the mangroves and false waters.

but don't forget the cat eyed snakes, and kraits, a lot of sea snakes are rear fanged, the entire Boiga genus, not just the mangroves. there are tons of rear fanged I can't even think of now.

Coral's are full on HOTs not a rear-fanger.

As with all venoumous species the true level of how dangerous they are is more dependent on the person then the snake.

Coral's are full on HOTs not a rear-fanger.


I think she meant the false corals, kinda like the false water cobras. not the actual corals. those are elapids I think.

Yes true corals are in the Elapid family.

Never heard of false Corals.....have heard of false Garters though, they are pretty sweet too! :wamma:

ya, i agree with janeo bro. diff ppl have diff reaction towards the venom...
i kept 4 mangrove snake, 2 teenager and 2 baby. one of the teenager give me a bite b4... but i think it is "dry bite".... it din inject the venom to me (so lucky).... if not my hand sure swollen... but those snake quite ok to handle with.... my opinion, i think that the mangrove snake is the fundamental for keeping venom snake.

my thoughts....i have no list and don't study these animals.....but if the snake eats frogs and toads, and it's "fangs" produce no venom...then wouldn't these "fangs" just be popper teeth....toads and frogs will swell with air and i've seen snakes pop them and eat em...some of these toads even had eggs pour out of the holes and the snakes sucked down the eggs also....toads are venomous and a snakes eats one, and you get bite soon after?.... i know a guy who got bit by an eastern garter snake and his hand swelled up....i asked if the snake had a lump and he said it regurged a toad soon after he secured it in a pillow case....

so my question? has anyone ever milked a hognose or other snake like these

Coral's are full on HOTs not a rear-fanger.

Yes they are "full on hots", but they are also rear-fanged. To the best of my knowledge, they are the only "full on hot" rear fang in the US. Let's make sure we know the correct use of terms. Rear-fanged describes the placement of the "fangs", and does include several highly venemous species, such as the coral snake and the boomslang. It also refers to harmless animals such as hognose and ring necks.

Corals are not rear-fanged. They are front fanged Elapids.

My apologies.....you are quite correct. I always thought they were rear fanged, and thus the reason I have always heard that they had to really chew on you to envenomate you. Teach me to open my mouth without double checking what I thought were facts.

No biggy. I am an ex-venomous keeper, had to sell out do to moving into a different city that is a no HOT zone. Corals are a lot less likely to bite then most other Elapids, however they can cause some damage if they do. Again, it all depends on the person as well.

There are a lot of rear fanged snakes out there that most have never known about. Most have no clue that ring-necks are rear-fanged. There is still so much to be learned about these cool snakes. I loved watching my Giant Hogs feed.....it was interesting just how quick the venom worked on rodents.

I hear things like that, but my experiences with easterns lead me to think no venom. I once got a panicked call from my sister about a snake in the yard. By the time I got there her husband had already captured it. He was standing there holding it at arms length by the neck. I take the poor thing from him and it immediately regurges a toad. The toad is still alive and hops off. I grab the toad and rinse it off, and it lives. Couldn't refeed it after that, felt like it diserved to live. So obviously, it had not been envenomated. Just a curious thing to me in the whole venom debate concerning hoggies.

my thoughts....i have no list and don't study these animals.....but if the snake eats frogs and toads, and it's "fangs" produce no venom...then wouldn't these "fangs" just be popper teeth....

so my question? has anyone ever milked a hognose or other snake like these

they do produce venom. the fangs are basically altered teeth, not technically fangs for rear fanged snakes. they're shorter teeth that have grooves which the venom travels down, somewhat like a rain gutter. they have to actually break the skin, and then the venom works its way in and seeps in through wounds, not technically injected like front fanged hots. that's where the debate is. the toxicity isn't really studied, but they do produce true venom. the delivery method isn't very reliable for a "hot" bite. but still, not something to toy around with when there's minimal information.

it would be interesting to see if I could milk the false water cobras. I have looked at the rear fangs on my male when he was younger but wouldn't bother to now. seems like an awful lot of stress for an animal that already distrusts me.

I didn't see any from the Ahaetulla Genus. They are some of the most remarkable snakes on the planet. They are the only snake to have binocular vision.

Ahaetulla Prasina regularly shows up in the pet trade but due to their wild caught status and preference for lizard prey they make a tough, if not impossible captive.

Where did the information come regarding the Farancia abacura? to my knowledge, they were a nonvenomous colubrid.
