It is known 77 genera and about 600 species of Scorpions, who live in all parts of the world with warm climate. According to morphological characteristics they are divided into two families: Buthidae and Chactidae. Many generations of SEM. Buthidae live along the borders of deserts from the Atlantic ocean to India; in the fauna of India there are more than 80 species. In the Palearctic is about 100 species, of which about 15 species in the fauna of the USSR. Scorpions SEM. Chactidae common in the southern part of Europe, in
Asia minor and North Africa. On the black sea coast of the Caucasus meet Italian (Eupeus italicus), in Western Transcaucasia - Mingrelian (Eu. mingrelicus), on the southern coast of Crimea - the Crimean (Eu. tauricus) Scorpions, But a. eupeus and But. caucasicus live on the territory of Central Asia, Kazakhstan, Transcaucasia, Lower Volga region.
The body of Scorpio comprises three departments. On the shield of cephalothorax - a pair of large, and on each side up to 5 pairs of small eyes. Solid cuticle formed flaps of the trunk and extremities segments. This broad division - peregrebnoye. Narrow cylindrical rear Department - sanabresa; metasoma, or tail, ends swollen tail segment, where are placed gland that produces poison and duct opening on the end of the curve sharp sting. Golovogrud with a pair of small upper jaw in the form of small claw, servants-grinding production. Under the golovogrud - big novoshepelichi ending with big claws, serving to capture prey. The "tail" jointed, flexible, curves up ahead and to the side, which gives the Scorpion able to sting in any position. Production Scorpions grab claws of palp, leading it to the chelicerae, knead and absorb, when resistance - sting, paralyzing the victim poison, and then eat it. ; Color But. caucasicus varies from light yellow to orange, dark-ochre, sometimes to black-brown. From But. eupeus is less length of the 5th segment Sanabria, larger and more irregular grains that make up the keel on this segment (P. I. Marikovsky, 1954).

In Nakhichevan Autonomous Republic and in the adjacent part of Armenia there is very poisonous large tropical appearance But. crassicauda. This "Tolstoy" Scorpio black, up to 10 cm; meet and larger specimens (Fig. 7). The species is distributed from the Eastern shores of the Mediterranean to India.
Live Scorpions in the foothills, canyons, gullies, various deserts, more rocky, where many insects, centipedes and spiders. They are not able to endure high temperature and corrosive dryness. With the onset of cold weather hibernate, lying outwards in the crevices of the rocks under the big stones, deep in the ground, sometimes in the houses of man (in Nakhichevan ASSR from the middle of October, in Almaty region since the end of September - beginning of October).
Multiply by Scorpions mating preceded by a "marriage walk": male and female, locking their claws, vertically raise "tails" and walk together 1-3 days; copulation occurs in the shelter. Most Scorpios viviparous, some asciiword; embryonic development occurs in the body of the mother from a few months to 1 year or more. Embryos from 5-6 to several dozens. The birth of a juvenile occurs in early August. Newborn 7-10 days cling to your mother's back, eat inactive; after the first molt reset mother, and lead an independent life. Scorpions can permanently to starve. Most species do without water. Lifetime Scorpions 5 years (P. I. Marikovsky, 1954).
