Odontobuthus scorpion belongs to Buthidae family and is extensively distributed in south proviences or Iran, in this research we studied the amount of sodium(Na), potassium(K), calcium (ca) and copper(cu) electrolytes in haemlymph in different thermal ranges. The estimated amount of each electrolyte was 280.41 ,6.85 , 10.82 and 31.82 mEq/L respectively, statistical analysis considering environment temperature and sexes of scorpions showed that the changes in temperature has a significant effect (p < 0.00l)on electrolyte content of haemolymph. While sexuality has no effect on electrolyte content. The scorpion fights we increased environment temperature with increase of haemolymph osotic pressure and in this case the most important electrolytes are sodium and potassium , which have a greater shares in this adjustment. Lethal temperature and water loss rates of scorpions indicate that these arthropods are quite tolerant to hot dry desert conditions.
