The Fiercer Sex: Why Female Scorpions Sting More Quickly

Female scorpions may sting more quickly to compensate for their slower running speed, new research shows.

And that sluggish running, and extra female fierceness, may be a result of the extra weight they carry from pregnancy, the researchers said.

"The females are heavier, and they can't sprint as fast," said study co-author Bradley Carlson, an ecologist at The Pennsylvania State University. "Heavier ones have to compensate for that by stinging more."

Past studies had suggested that female scorpions tended to be extra aggressive, wielding their venom-packed stingers more quickly in comparison to males.
