This is the best quality I can get with a smartphone camera through dusty plastic.
Anyone got any input? I've been trying to get my hands on an exuvium, but most of the time it is too mangled to be useful.

i would guess male because of the dot.

Does anyone have any pics of male and female moots from Pink Salmon Bird Eater? I want to know what I am looking for. Also, I was told by Tarantula Canada that I would be able to determine sex until sling is at least 1.5 inches? Accurate?

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!

I'm not sure which sp. but there are MM that don't have tibial hooks, also I know not of any female T's that have hooks. I'm sure a qick google would confirm the sp. I'm referring to.

Does anyone care to take an educated guess? I'm sorry if the photo is too poor.

Recently I was looking through the boards to find photos of spermathecae for reference to help identify a species. This was no easy feat as there is so many threads of a similar topic.

I thought I would start this thread to make it easier to access photos of spermathecae all different species in the one place. I think having a thread dedicated to images of spermathecae will be beneficial to members. Hopefully they will be able to find what they need by having a quick flick through the thread.

Could members with clear images of developed or near developed spermathecae can share their images here with the species captioned to get the ball rolling.

I will post a few to start-

Monocentropus lambertoni


Chaetopelma olivaceum


Brachypelma schroederi


Ornithoctoninae sp. 'Ho Chi Minh'

 

[Flexzone]

Nhandu chromatus

 

[Tim Benzedrine]

Those are very clear shots.

@viper69 @Austin S. do you have any??

Luckily I saved above 1,000 molts of various species, just for this

LOL.

I'll be receiving some molts in the mail to sex in a few days too.
Expect a LOT of pictures.
This is actually a really good idea. Just bustin your .

Spermatheca from a few select adult females in my collection. Very interesting to see the...

 

[KezyGLA]

Yeah, if you can get any close up images that would be awesome. To be honest, I wouldnt mind drawings as long as species depicted. But photos are the best for reference

 

[viper69]

@viper69 @Austin S. do you have any??

Sorry mate, but the Orni certainly appears what could be female though, IF similar to other species.

Yeah they are. Good examples too
