I had 50 slings of these once, when they first came into the hobby and nobody was really too sure about them. It was a little nerve-wracking to feed them. Dropping crickets into their containers spooked them right up, out the vial, up my arm and occasionally into my armpits :blink: Bitey and fairly venomous little things, but I never was bitten!
That's a really great photo, not to mention a pretty typical pose
