Scorpion Species Alacran tartarus

The scorpion species Alacran tartarus, from the family Typhlochactidae, has been found at the greatest depth of all scorpions--750 to 920 meters below the surface in the Sistema Huautla, Oaxaco, Mexico. The family Typhlochactidae, which includes nine species of scorpions endemic to the karstic regions of eastern Mexico, have adapted to the dark with features such as loss of eyes and reduced pigmentation. Included in the family are one of the world's smallest scorpions, Typhlochactas mitchelli, and the scorpion found at the greatest depth (nearly 1 kilometer below the surface), Alacran tartarus.
