Emperor scorpions are one of the largest scorpions in the world and live in the savannahs and rainforests of West Africa. Like all other scorpions they glow under ultraviolet light and navigate by starlight. I saw this one in the Atewa Forest in Ghana.
The general rule to assess whether a scorpion poses a danger to humans is if it has a bigger sting compared to its pincers. Emperors, although big, are not venomous enough to kill a person unlike some of the others that live in the same forests and grasslands.
