So I've been looking for the rattlesnake T lately. I keep coming across its scientific name as being Selenocosmia crassipes but dont see it being the same? If anyone has a site or breeder that's selling them lmk!

They get that moniker from the fact that they are known to stridulate, which a lot of species have the capability of doing. If you're getting it solely based on that trait, it isn't as if they do it all the time. They need to be in a defensive mode and the only time I've seen it happen is because they've been antagonized into doing it.
If not antagonized, you can have one and never have it stridulate it's entire life.

Right! Dont want it solely for that purpose or to antagonize it but never have heard a T stridulate like that before! Any information on its scientific name would be helpful. Thanks

Have you cared for tarantula's before?
Have about 9 or 10 atm!

They are a fast, fairly defensive, old world species from Australia with medically significant venom. I would not recommend this species, or any from that genus at all, for someone without some pretty significant experience under their belts. I think that this is the genus that has been reported as killing dogs with their venom. Australian species are sometimes difficult to find as Australia has very strict rules on export and not all species are being bred outside of Australia. If you search this forum using the scientific name, you will surely find all the care information that you require.
This species is also referred to as the barking spider and whistling spider.

Ah, so it's the Selenocosmia crassipes. I feel like theres a good chance it's not the whistling spider. Read many people saying they cant wait for the rattlesnake T to come to the hobby years ago. But like you said. Australia has strict rules for exporting. Already had the S. crassipes in checkout on palpfriction. Will grab her(hopefully) and see! Thanks guys

That name can be given to any tarantula who can stridulate - that is why common names are garbage and should never be used.

The rattlesnake tarantula in the video you posted is not Selenocosmia crassipes and is not available in the American tarantula hobby. The rattlesnake tarantula is something completely different and has not been classified at this time. Unfortunately, the link the newsletter of the Australian Tarantula Association that has more information on this tarantula has gone offline. A Google search of "australian tarantula association rattlesnake tarantula" brings up a link to the newsletter I'm referring to, but I can not vouch for the site it is hosted on and thus won't link to it here.

Yes, I remember a discussion one of our Australian members (can't remember which one) was having about this species. I do remember he couldn't even get one in Australia yet, so good luck to anyone looking anywhere else in the world.

@jigalojey had mentioned them a while back with some good footage.

@VanessaS while it is stridulation, its pretty unique, Ive never heard any t like it, it really does sound like a rattler and its loud.

Theyre discussed as part of a documentary, accordingly, the scientists who discovered them deliberately delayed their naming and locations to prevent predation from collectors. It’s neat, but they live in burrows, ie pet holes

That could just be that individual, though. That video doesn't show it making a different sound than others - just a louder one. That could be due to a number of different factors.

I didn't watch this vid....I am going by the vids and descriptions posted by an Aussie years ago.

edit, just watched this one....what was posted years ago didn't sound like that one....but its still really unique iMO.

It comes down to just one factor that makes the rattlesnake tarantula's stridulation unique. The stridulating organ of these rattlesnake tarantulas is massive! The prolateral maxillae consists of large lyra and a large thick brush of setae above it. While most selenocosmiine species have this, it is especially enlarged in the rattlesnake tarantula. Unfortunately, there are no images of the strikers on the retrolateral chelicerae. I guess it needs to stay a secret until someone publishes the description paper. I really wish the original link to the Australian Tarantula Association newsletter that has a picture of this was still active. You can find it through Google search though.

Look into Haplocosmia Himalayana. They also have a unique stridulation sound.

Greetings OP. It's already been touched on a few times, but yes this tarantula is Australian and therefore we can already (unfortunately) rule out it's availability anywhere else.
Secondly, it's NOT confirmed to be in Phlogius/Selenocosmia, I speculate it's more closely related to Selenotholus given how readily Selenotholus sp. will hiss and how easy it triggers (even non defensive fang movement -like catching food and intense grooming- from S.Kotzman, will produce a very audible hissing sound).

The sound made by rattlers is alleged to be quite distinct from the average hissing most other T's can make, in both the noise itself and volume they produce it at, but having only seen videos and never encountered one I can't really vouch for that. The videos sound alot different to regular T's IMO.

They can pop up for sale very rarely by some people who catch them in the wild, but as also stated I don't think they're officially classified yet. Often times collectors make a rough guess on what genus the specimen is and just name the species after wherever they found it. Because of this, in sure many Aussies probably have rattlers in their collections that are mislabeled and they have no idea.

It's just one of a large number of documented but unofficially named T's we have here Down Under, I'm sure sooner or later we will get some better info on them

Sorry to bring up an old thread Just doing a but of research. Are you saying that Australian Ts are no longer available for sale in the US as they were around 6 years ago or so?

Assuie Ts are available! I just grabbed a s. Crassipes a couple weeks ago. Just THIS T isnt available yet. I forgot to check this thread again and many people are correct as I just researched on my own. They're protecting this T (rattlesnake tarantula) and it will be hard to export it. I've been hoping to find it for so long now and people were relating it to the Selenocosmia species but they are not the same.
