Advertisement No im not going by Manny Rubio's book, Im going by the sting reports of each species. They are not overly dangerous, All scorpions can be fatal. It depends on a lot of things. If your allergic, how much venom injected, the size of the scorpion. I don't see C. vittatus and C. hentzi as dangerous, medically significant scorpions. If you use common sense its almost impossible to get stung such as always using forceps and never sticking your hand in the cage and I'm getting tired of hearing they are "aggressive" but I dont think I lucked out with 6 specimens.
