Is this the first two-tailed scorpion?



Other accounts of two-tailed scorpions exist and several museums and universities have preserved specimens in their collections. (For a list of other species that have been noted with two tails, see the list below) In fact, two-tailed scorpions were once thought to be in their own group, apart from scorpions with one tail!

Do both tails move?



Here at the Sonoran Arthropod Studies Institute,we have observed that both telsons (tails) are capable of movement and are held either crossed over one another or arched side-by-side. Pepe exhibits behaviors similar to other bark scorpions such as walking upside down beneath objects and holding the body very flat on the ground.

Is one tail dominant over the other?

In one observation of Pepe using her tails to subdue a cricket, the right tail appeared to be the tool of choice. Upon approaching the cricket, Pepe grabbed its abdomen with the left claw and pierced the cricket with her right tail. About ten minutes later, Pepe stung the cricket again with the right tail. More observations are needed to study tail usage and behavior.
