Male or female ?

the first picture is on an awkward angle, so it is hard for me to make a confident guess.
That P. metallica I believe i'm seeing an epigastric furrow, but i'd wait for someone to second that. I'd like a closer picture if possible.
B. boehmei female.

The 3rd looks female to me, your best off looking at the shed skin tho. Not always accurate looking underneath...

 

[Skeri]

JoeMean is correct. Although I find it accurate enough in most cases. Honestly, the P. metallica looking at the coloration of it, what I said is a guess. Mine I have only guessed at the sex due to it being so small, and considering mine is about to molt due to suddenly visible yellow markings and having an over all darkened appearace (P. metallicas have a cremeish translucency to them in the younger stages that becomes very dark when in premolt. I find them one of the easiest to tell the signs of premolt out of all my slings.) Its going to need a few molts for a more accurate ventral sexing.

The B. boehmei on the other hand very clearly displays and epigastric furrow. Of course its always best to confirm this by molt, but I can say pretty confidently that is a female. After you own enough Ts and have become pretty familiar with what male and female ventrals look like its not hard to give a pretty accurate ventral sexing. I find it particularly easiest in NW terrestrial species.

I'm not doing this to be a pain, more just as an FYI. There's a sub forum for sexing questions:

Just a small criticsm: It would have helped a lot to separate each photo+caption from the next with a couple of carriage returns. The "presentation" would have been prettier.

80% probability of being female. The epigynal plate is wider than it is long, and there's no sign of epiandrous fusillae.

70% probability of it being male. The epigynal plate is longer than wide. The flare from your flash is obscuring the presence or absence of epiandrous fusillae, so I can't tell whether it possesses them or not.

These are just guesses, hence the probabilities. What you really need to do is look at the inside of their exuviae.


Enjoy your little 8-legged sex-pots!

All tarantulas, males, females, babies, spiderlings, and adults, possess an epigastric furrow. Can you clarify your statement, please?

Thanks for your reply guys. As you can see I just joined this forum so I appologize for posting it here. These pictures was actually sent to me by Paul from Petcenterusa. I yet still have to decide if i want the P.Metallica and B.Boehmei. I purchased the Brazillian Black 2 weeks ago. I did however ended up with a 1.5" P.Regalis and a 3" Theraposa Stirmi (female). Cant wait for them to arrive. I now have 6 T's in total. Will be posting pics soon. Guys thanks again

Its hard to explain. The way I always was told to look is if there is a visible slit, its a female. If there isn't its a male. Thats been pretty accurate for me thus far when I have confirmed by molt. If there are other ways people don't mention them quite as frequently and i'm therefore not as practiced in looking for other things.

The epigastric furrow is the region you look at to ventrally sex a T, not a sexual organ itself. All Ts have an epigastric furrow.

I'm gonna take a shot lol. I'll say male male female.

 

[Skeri]

I'm aware, sometimes I just have difficulty explaining what I mean. What I was trying to say is the male and female parts look different. The female's appear more visible, sometimes somewhat raised, where as the males is much less visible. I'm admittedly often bad at explaining what i'm trying to say, and ontop of that when I wrote that I was running on zero sleep. My apologies, I should have better explained what I was trying to say. When I said clearly displays, I was trying to get across it was open and visible where as males it is straight across without that visible, noticeable opening.

While I know what you mean (I have a couple females who are very "obviously" female ventrally, confirmed via molt of course), this is not always true. Some females will surprise you, looking male ventrally but then proving female once the molt is inspected. Vice versa there have been plenty of cases of ventrally sexed females hooking out into MMs. Ventral sexing is handy for the ones that very obviously look male or female, but unfortunately that is not all of them (even same species can fool you).

(I can't help myself!)

Shell, I think the word you're actually looking for is "stupefy!"
