I may have misunderstood, i thought ATS was looking at good pics. But if it is differences, then ther is none, because this lowland/highland thing is a salestrick. 3 of the best poecilotheria guys in europe has been to where they live, and lowland are as big as ornata, and is darker than highland. I have never seen such lowland in the hobby. In their book they have pictures of highland and lowland, and detailed differences. That is why i say sales trick. I allways sell my subfusca, as subfusca, period;)
I highly doubt lowland are in the hobby, because if they were, these guys would have taken them home, bred them, and earned a lot of money;) Germany is maybe the market where most different kind of T´s are available.
