Reason for choosing the topic Scorpions are one of the oldest groups of arthropoda in both genetics and morphology. Currently more than 2 000 species of scorpions have been recorded distributed on most continents except Antarctica New Zealand northern Patagonia and the Antarctic islands. Scorpions are carnivores food in nature consisting of insects and small animals such as cockroaches grasshoppers locusts mantis many other invertebrates. Scorpions are often found under layers of soil rocks and rotten wood they can burrow in shallow sandy layers. Scorpion plays an important role in human life in the fields of economics agriculture forestry medicine the environment and has a major role in establishing biological balance in nature. In nature scorpions reproduce a lot but are poorly developed and the survival in the offspring is not high. In addition today the habitat is destroyed along with the mass exploitation for food and medicine so the number of scorpions is decreasing. The habitat of scorpions is
