Sexing for Dummies

[Snipes]

I think perhaps the best way to help people learn to sex would be just to show photos of each gender. I will get the ball rolling. This is a female B. smithi.

http://i2.photobucket.com/albums/y31/Snipes05/Tarantulas/Sexing%20Pics/snithianalysis.jpg
Note the flap on the molt. Its the give-away for females. Absense of some sort of flap indicates a male, but remember to look closely! Some are tricky.

1. Males, especially more mature males may have a patch of somewhat thick hairs here.
2. More of a lip (this is where males deposit sperm). Males sometimes appear to have a "hole".
3. In comparison, females have a farther distance between the second book lungs.
4. Males sometimes appear to have a "half circle" patch. It is absent here. Sorry, its asymetrical.
The other two things have no significance, i just couldnt help myself :8o

great thread much appriciated, but errr what exactly am i looking for?

[Snipes]

thanks for the pics becca. With the females you are looking for the flap on the molt. Look at all the female pics and you will find it on all the molt pics. I still have trouble with ventral shots, but with these shots i hope to get better and learn.

can we get some good definite vental shots?

Here's a molt from a fasciatus I have at my work...and since I own a female as you can see from my previous post, I'll be buying him for breeding once he matures...

[surena]

Does anyone have a ventral shot of a confirmed female or male Ephebopus cyanognathus (Bluefang) ?
Also at what size do they usually mature ? I know that they don't get very big, would you say that they get about an OBT size when matured ?

[zLOST]

i think, that this is pretty self-explanatory. i've used the males final molt in this setup.

[smof]

I'm curious as to if anyone has some ventral shots of male/female B. smithi, or similar looking T's? My T is too small to seriously determine the sex, but it'd be interesting to have a guess.

Well, this is all peachy, however, all of you are forgetting one little MAJOR thing, not all tarantulas are female AND it's just as important for those new to the hobby to also be able to know and detect the epiandrous fusillae as well.

Well, think of it this way. How can you tell what sex a baby human is? If there were a thread on that, there would be pics on males because they are the most obvious. So a lack of the ahem, distinctive factor would suggest a female. It is exactly the opposite here, with females having the "thingy" and males not. So what you need to look for is the absense of any of the different female flaps.
edit: Oh, i forgot to mention, DO NOT post pics of naked babies here :), or anywhere for that matter. Twas just an example that everyone would be able to understand.

You are absolutely correct, in part. To use your example with human babies (no pix posted:D ) the male organs may be obvious, however, that is not always the case, as there are many times (with humans) that upon birth, it is not so easy to determine gender if the external orgains are not either fully developed or descended. It is just as easy or difficult to identify a human female as it is a male by the same method.
Since this thread is, by it's title, for "dummies" then, don't you think, for the sake of having a well rounded knowledge and understanding, that a novice should be aquainted with both aspects of sexing tarantulas, thus, covering the whole spectrum?
Going by the presence or absence of spermacathacae can and has been proven to be misleading in its own right, especially with smaller spiderlings and with those not familiar with sexing and who do not know the differences in appearence from species to species. Unlike humans, who's genitals all look the same (generally speaking), a female tarantula's spermacathcae can look very different from one species to the next, whereas the epiandrous fusillae of the males look basically the same from species to species.
In addition, the spermacathacae can be very difficult to see in a small spiderling due to development level or lack thereof, whereas the fusillae of a male is more clearly visible at a much earlier instar.
Just because there doesn't appear to be a "pouch" or "flap" does not always mean it's a male and just because there does appear to be such does not always mean it's a female, especially when the person doing the sexing isn't 100% certain what they are even looking at or for.
So, my point is, if we're going to teach how to prooperly sex tarantulas, we need to be showing how to and what to look for with regard to male tarantulas as well as female.

Hi i'm getting a B.smithi soon and I was wondering if it's posible to tell
if it's male or female by build a molt befor maturity?

Same spider as above, male smithi.
http://tangeroo.nome.ca/pictures/tarantulas/smithers-040406-vent2.jpg/smithers-040406-vent2.jpg

I think the different-textured patch of hair that is a sign of maleness is pretty clear in all these shots. Somebody correct me if I think I'm seeing something that I'm not ;)
Note that the 2 photos of the Chaco were taken of an exuvium which has dried out, which I think contributes to the clarity. It was nowhere near that clear when he was still wearing it. The smithi shots are from a live spider tho.

This is a fabulous thread. I'm trying to give myself a crash course on sexing T's based on all the "sex my . . . " threads in this forum. The trouble is that there is alot of dissagreement on most of them.

It would be great if more people would post pictures of their confirmed sex tarantulas to give us newbies a chance to learn the differences.

(yes, I'm being greedy, I know this thread already has a bunch of great pictures - i just want more!)

Thanks!

Note: Avic molts are usually really twisted up and this one was no exeption. Pluse it was a day old and hard. Here is the trick, take a small cup of water mixed with dish soap, and dunk the exuvia. Avic molts usually are in a way that the legs are all pointed up and so the body is at the bottom, so just dunk the bottom. Then it is all too easy to open the molt up.

[NixHexDude]

Is there anyway we can get a few pics of the procedure you guys use to stretch out the opisthosoma of the exuviums? This is the part I have problems with.

I don't have any pics and there's really not enough involved in opening an exuvium for sexing to justify taking them. Sorry. :D Moisten the exuvium with water, a mix of water + dish soap, window cleaner, or whatever you want to use and use a couple straight pins, needles, fine-tipped tweezers, or whatever to open the abdomen of the exuvium. Pretty simple. Just give the water time to soften it up and work slowly and carefully.

This is all very informative. I'm doing my best to sex my 5" Avic sp Peru Purple molt but i'm kind of confused. I haven't developed an eye for these things yet so any more avicularia pictures would be really helpful! You guys are great!

Huahini 1 looks undeniably male to me, and #2 appears female. I am no huahini expert though, so second opinions would be splendiferous.

[SuperRad]

It seems like this would be a much easier sure fire way to tell a male from a female.

Are there species that don't have tibial hooks on the males? Are there females that might have weird legs that have hook like parts? It just seems that most ppl prefer to ventrally sex or check out molts to tell. I would think hooks were the way to go every time.

Hooks and palpal bulbs only appear on mature males, meaning when they've had their ultimate molt. Up until then, pre-ultimate male tarantulas can look just like a juvenile/sub-adult female tarantula. Some have said that pre-ultimate males look "leggier" than females, but that isn't any sort of guarantee. Ultimately, the best way to discern pre-ultimate male from female is via exuvium.
Additionally, I have heard of a couple of species of tarantula where even the mature males do not develop the tibial hooks. I'm not sure which species these are (or how many exist), but perhaps someone else can enlighten us? :)
I have not heard of a single individual tarantula, or even any species, where the female develops anything even close to a hook. Perhaps some sort of deformity could occur rarely, but even then it would have to be on both legs which would be even more rare.
Hope this answered your question!

[SuperRad]

That helped a lot. Great info on that. Now that means I've got an unmolted sexless Aviculara aviculara with no name.

Damn, I'm too impatient to wait for that either. Just guess I'll name it Kelly and if it's a male I'll just have to say he's Irish or something.

[Talkenlate04]

how about the other huahini?? those are two huahini's i posted.. Thanks for your reply..

I missed one....... Crap lol I did not see the Rosea slipped in there above the curly.

Haha! That's cute :)
Don't feel bad for having a nameless tarantula...I have a c.fasciatum female that I am stumped with, I haven't come up with a name for her yet. I don't want to name her something generic like Tigger or Stripey McSpider...
Anyhow, back to sexing:
Could you possibly get a ventral shot of your avic? A little blurriness is ok (though not preferred hehe), but we could at least inspect it and hope for the best! {D
What size is your avic? If it's still kind of small, a molt may happen sooner than you think, which would be great!

[SuperRad]

Kelly is 3.5 " and I just got it a week before x-mas or something.

I just got a tight point and shoot with awesome zoom and macro capabilities, so I planned to figure it out over the New Years break and post some stuff in the sexing threads for Kelly and my Rosie which I think is female.

Thanks for being so helpful!

I think male. Yes?

[Talkenlate04]

Yes you have a male.

[TalonAWD]

Help me cause I'm in doubt. Male or female. Its a B. boehmei.

i say female

[Talkenlate04]

i say female

Can you please explain why you think that? I am curious.

[thedude]

im prolyl wrong lol, but to me it looks like there is a wide space between the first set of booklungs.. that the best way i could explain it lol

[Talkenlate04]

Do you see dense patch of black hairs above the epigastric furrow? Those are only there for males. I'd take a picture of my female, but I am not in the mood for a round of itching! :(

[TalonAWD]

i say female

Ah man, you are playing with my feelings! Is there a comparison of male boehmei and female to compare mine to?

This is my all time favorite tarantula. Very very docile and NEVER EVER hides. And the best part is that it stridulates when annoyed with its front small legs!

Edit: Talkinlate04, thanks for explaining it. Now I see what I'm supposed to look for.

[TalonAWD]

Chromatopelma cyaneopubescens

Ok Got another one. I say female but want another opinion. Its my GBB molt at around 3 inches. It has a kind of extra flap. At first I thought male but found that flap. I can move it with the pointy stick.

Finally.

Congratulations, you got a Female. :) The flap defenitely makes it a female to me.

2. More of a lip (this is where males deposit sperm). Males sometimes appear to have a "hole".


Can anybody post a clear pic this "hole" that appears on males? I'm guessing its that white dot?

[Kris-wIth-a-K]

Hole????? :? Are you talking about ventral sexing??? Males have the Arks of hair on the furrow if that is what you are talking about.

[TalonAWD]

Can anybody post a clear pic this "hole" that appears on males? I'm guessing its that white dot?

Yes the white dot is a male trait.
