More info: Centruroides exilicauda is a destert area species that spends most time in trees and plants. Substrate is not important, just climbing space. Communities can be dense with as many as 2 adults per gallon of space. (at the time of this writing, I have 17 in a 10gallon tank.

This species is one of the most venomous in North America. An antivenin was created 40+ years ago and no one has died from a sting from this species since its creation. However, it has killed more people in the US than the Black Widow Spider.

Males can be easily identified by their enlongated metasoma (such as picture above).

Arizona Bark Scorpions also have a "morph" that looks slightly different than "normal" Arizona Barks. It is known as the "Gertschi morph" and for many years, the two were considered separate species. Photos of the Gertschi morph can be found in the C. exilicauda photo gallery
