My son would like to ask if anyone could “sex” his tarantulas.

Thank you in advance for helping

Brilliant pictures.
My guess would be top - female and bottom - possible male

I agree with @Enn49 I also think the top is a T. stirmi and the bottom is a pamphobeteus @Casey K. Would you agree?

 

[Casey K.]

Theraphosa stirmi and Avicularia purpurea? Hehehehe Both female!

 

[NorseDad]

Lrege size and brown coloration? Must be a female T. sturmi.

Those vibrant purples must be a freshly molted Pamphobeteus male.
