they grow VERY VERY slow. John Hoke showed me a g. rosea that was 3 years old and it was still a sling! I didn't believe him at first but I said to myself why would john lie about something like this. LOLWell, actually those pictures are *very small.* You might not have noticed. However, I'd throw an ax at female, as well. As for age, that is pretty much impossible to tell. Rosies tend to be pretty slow growers, but I've ne'er raised one from a s'ling so I'm not entirely sure how slow.
How d'ya figure? I don't see much of a bald spot.
scratching head, HUHLooks like a female to me. If they have 3 or more inch leg span and it still doesn't have the spermhooks at the end of each pedipalps it's probably a female, which yours seem likely to be. And their appear to be no web making organ, which looks like little hair, in the area right above the epigastric furrow, so it's female in my opinion, but the picture is kindda on the small side.
i never heard of sperm hooks lolDo a search on Rick West. His website will pop up and go the part about sexing spider. It show exactly what I mean about the silk making organs the male use to build a sperm web. And on Stan Schultz website the part about G. rosea caresheet it will tell you that a rosie with three inch or more leg span is a female if it hasn't develop the spermhooks at the end of each pedipalps.
you should order some from Ryan , he has the best prices right now i know of . Of course he had over 2000 slings too...That's what I mean...tibial hooks. Sorry, I haven't posted on about tarantula for such a long time. I have been busy and more involve with my green iguana and other reptiles. I am now just beginning to get into T once again, and I'm hoping someone will ship me a female B. smithi soon.
