Though most of the posts I've read say that blondi and stirmi are identical except for hair on the patellas and a few other none obvious features, a few web pages have indicated that the maximum size of blondi is greater than that of stirmi. One page said that stirmi max out at 10" for blondi it's 11". Searching pictures here just about all of the really large Theraphosa are stirmi. Does anyone know for certain whether there is any size/growth difference between the two species?
