|This family consists of 6 genera and 21 species (until 1998). They are
distributed in western North America, South America, Asia
(Turkey) and Europe (Greece). A common characteristic of the
genera in this family is the presence of a large darkened
tooth on the internal margin of the cheliceral movable finger.
This characteristic is unknown in other scorpions. Many of the
scorpions in this family inhabit arid and semi-arid habitats.
Some of them also experience "winter conditions" during the
Several species in this family are popular in captivity,
and are easily obtained through suppliers. Especially popular
are the scorpions in the genus Hadrurus because they
are large, long-lived, and easy to keep in captivity.
The scorpions in this family can deliver painful stings,
but are not of medical importance. They will sting if
disturbed or provoked.
