Haplopelma longipies venom question

[JAFUENTES]

What would haplopelma longipies venom be classified as? Is it a neurotoxin, cytotoxic, all I know is that it isn't hemotoxic.

 

[14pokies]

Crickotoxic?

 

[Toxoderidae]

May I ask why you're asking all these venom questions? just kind of odd.

My guess is the light blew in his T room.. He decided to be a cowboy, worked on his Ts in complete darkness( like a beast) got tagged and is now narrowing down what bit him by our description of various venoms...

Im 100% confident that this is what happened...

Very good theory. Best way to avoid needing to know about tarantula venom is to only keep species that are within your skill level, have secure caging, to use forceps/tongs for all cage maintenance, and not to handle or touch your spiders. People that do this don't seem to ask questions about venom.

Ludicrous, none of that will keep a light bulb from blowing...

What would haplopelma minax venom be classified as? Is it a neurotoxin, cytotoxic, all I know is that it isn't hemotoxic.

All you need to know is they are hands off, very bad tempered T. But if you have to know i do have some information. My wifes family lives where haplopelma longipes exist, and i have been collecting them many times.
I have talked to a few of the local guys who actually have been bitten by them, they all say the same thing, they hurt like he.. at first and you get sick for 2 weeks with all kind of unpleasants problems to your body. They have great respect for them. But not enough respect i guess, because they do eat them also....
I think that should be enough info about venom for you.

I assume all Haplopelma genus carry that protein. Some, like Haplopelma hainanum, deliver more venom with the bite, so that's IMO the reason why those last in particular are viewed as more "hot" among the genus.
Haplopelma genus motto is: "all the venom you want". Their venom isn't worst than a Stromatopelma calceatum or a Pterinochilus murinus... actually, the one of those (Baboons i mean) IMO is a bit stronger; just that the venom quantity given with a bite by "Haplos" is more than the average, plus those OW's are famous for more than one bite in a row. Expect two bites, or more, within seconds.

T's carry a neurotoxic venom, "necro" or a "cyto" one belongs to true spiders like Sicarius hahni, Loxosceles laeta etc and thank God.

Now i tell you about a Theraphosidae with a powerful venom that is a bit underestimated (because there's very very bite reports) and that can even cause heart problems in the long run if you are very unlucky: Chilobrachys fimbriatus.

Toxic Avenger? This is a deja-vu or i'm crazy like "In the mouth of madness" perhaps?

Some people don't understand why so many of us are against handling, or beginners getting advanced species.

It is allways a better idea to start small and work forward to a bigger goal!

Absolutely. It takes everyone a while to get a feel for tarantulas: their speed, temperaments, needs, etc. I don't want anyone having their spider race out of it's cage and across the room, when they had no idea that could happen. You can be sloppier in techniques with the calmer NW terrestrials. Things need to tighten up when you get into tropicals, OW's and arboreals. When you acquire species in stages, you have time to adapt your techniques. Stan Schultz was able to get away with things with his Brachys and Aphonos that I'd never dream of doing with my lunatics.

- Their venom isn't worse than a Stromatopelma calceatum or a Pterinochilus murinus... actually, the one of those (Baboons i mean) IMO is a bit stronger; just that the venom quantity given with a bite by "Haplos" is more than the average, plus those OW's are famous for more than one bite in a row. Expect two bites, or more, within seconds.

- a Theraphosidae with a powerful venom that is a bit underestimated (because there's very very bite reports) and that can even cause heart problems in the long run if you are very unlucky: Chilobrachys fimbriatus.

- Not only fast multiple bites, but some will hang on and either pump more venom in, or chew and tear up tissue. When you think about all the animals that eat tarantulas, spiders look at intruders as something that may eat them, that they could be dead in seconds. I'd be feisty too.

- Stromatopelma bites have been reported to cause heart arrhythmia, which is serious business. I'd suspect this may not be rare in OW's. Lacking the passive defense of flinging hairs from a distance, OW's usually take a more pro-active approach to self defense. 'Hands on' as it were.

hey jafuentes
goto a science journal website or similar place where you get search , such as pubmed

type your spider genus + venom

then research on your own. I really hope you do not make another post with another species of Tarantula and venom questions.

you cant even pick the right one. you wrote longipes then you ask about minax venom. what the hell is going on?

It helps to know physiology. Many white papers won't come out and ID as stoat toxin or whatever. Only describe the physiological effects which categorize how the venom works.

Stan worked with calm NW as you know, so no wonder why he got away with a few bites only, i would not have even guessed how many he would have had if it was with poecilotheria he worked with in such manner! But he have never handled any T with the purpose of "see how brave i am".
So for once we are not in disagreement, gotta count for something

It does not matter if haplo are worse or not than any other ow, what matters is that they all can ruin you day, or ruin many days after. I know a taxonomist that have taken a bite from a chilobrachy, and he cried like a baby the following hour, it hurt i can tell you! My point is simple, if getting into old worlds T´s people have to be more responsible, there are vastly different results when they tag you, so regardless of wich OW you get you have to be more careful.
The true spiders you name there i already have at my home, but they really dont belong in this discussion, they have the potential to kil you and should only be acquired with the same safety concerns as hot snakes!

I mentioned true spiders only because JAFUENTES talked about cytotoxic venom, and, as far as i know only those (when it comes to spiders i mean) possess that type of venom, not Theraphosidae.
I agree with you but reality, sadly, say another thing. Lately here in Europe those true spiders are sold to people without the necessary experience for "handle" them (the internet in this case isn't exactly helpful but a damage).

Yes, unfortunately most people turn on youtube for advice how to act ariound T´s, that is very unfortunate....

I could tell you about several persons who are not qualified to own a cat, and much less a much more delicate animal as a T...
