Desert scorpions are the most common scorpions in the world. Of all the species, the desert scorpions are the most deadly to humans. Desert scorpions are found primarily in the arid regions of North Africa and Asia, as well as the southwestern U.S.
Desert scorpions are mostly light tan to yellow in color. This is to blend into their sandy surroundings. One member of this group, the deathstalker, or yellow scorpion, is extremely dangerous, producing the deadliest venom. Children and the elderly are known to be the main victims of this species of scorpion. Symptoms of this scorpion's sting can include high blood pressure, increased heart rate, fever, coma and even, death.
However, the deathstalker may have healing powers, as well. The neurotoxins in a deathstalker's venom have been tested medicinally, and have shown some potential in combating brain tumors in humans.
Another desert scorpion found in the U.S. is the giant desert hairy scorpion. This scorpion is light brown in color and can grow fairly large, up to 6 inches in length. It derives its name from the hairs found all over its body. These hairs sense prey through vibrations across the sand.
The desert hairy scorpion can be aggressive and will sting, but the sting of this scorpion is very mild and cannot hurt humans, unless a person has an allergic reaction to stings.
Desert scorpions are nocturnal and will seek shelter during the day to remain cool and retain moisture. They will hunt at night, seeking mostly insects as their prey. Desert scorpions feed on crickets and other insects.
As with most scorpions, desert scorpions can be very dangerous, and if you are bitten, seek medical attention immediately. Also, try to note the characteristics of the scorpion that stung you. The toxicity of the scorpion's sting can vary greatly depending on the species of desert scorpion.
