I think Blue is a she

Blue is the lab mascot, a Chromatopelma cyaneopubescens, and after their last molt, they’ve acquired the dark blue and blue-green colors of a mature greenbottle blue tarantula, and maybe reached sexual maturity. I’ve been checking out those palps, and they look very feminine to me.

Let me know what you think.

Fortunately, Blue is a perfectly good name for a female. Or male. Or immature juvenile.
