Advertisement Now maybe this can be interesting for you guys too. These pictures are taken from sibling poecilotheria Metallica. I am not sure if they are of different sex, since both are still very young ( maybe 2inch LS, same molt count ). However the coloration of their genital area is vastly different. It may be a good way of sexing Metallica early? I believe this one might be female (also a rectangle but lighter coloration) This one to be male (notice very dark rectangle) True connaisseurs are welcome to confirm it is possible to sex Metallica early like this and if these are of different gender? Maybe the difference in color is because of an imminent molt? Sorry for my English.
