The deathstalker scorpion catches its food by taking its prey by surprise. It hides under rocks in wait for an unsuspecting cricket or other small insect, then springs out and grabs it.

Within moments of being stung, the cricket is paralyzed or dead, giving the scorpion plenty of time to enjoy its meal.

About scorpion venom

Accidents caused by scorpion stings are a relatively common event in subtropical and tropical countries and can cause lethal envenomation in humans, especially in children. The signs of the scorpion envenomation are determined by the following: (a) scorpion species, (b) venom composition, and (c) the victim’s physiological reaction to the venom.About scorpion venom The symptoms of the sting start immediately with a few minutes after the sting and usually progress to a maximum severity within 5 hours. At this period the massive release of neurotransmitters results in sweating, nausea, and vomiting. The victims usually have the major signs, with the most common being mydriasis, nystagmus, hypersalivation, dysphagia, and restlessness.

The victims of scorpion envenoming that presented multi-system-organ failure characterized by changes in hormonal environment with a massive release of counter-regulatory hormones, such as catecholamine, glucagon, cortisol, angiotensin-II, and with decreased levels of insulin and an increase blood glucose level. The grading of these scorpions envenomation depends on local signs and whether or not neurological signs predominant.

About scorpion venom

scorpions use their sting for a variety of purposes. The most obvious use of the sting is in prey capture.

Prey that cannot be killed by simply crushing with the pincers is usually stung one or more times.

Scorpion uses its venom for both prey capture and defense. The venom is constituted by mucopolysaccharides, hyaluronidase, phospholipase, serotonin, histamine, enzyme inhibitors, and proteins namely neurotoxic peptid The signs of the scorpion envenomation are determined by the symptoms presented by victims of scorpion envenomation are usually complex in nature and can be attributed mainly to hyperactivity of the autonomic nervous system . The venom contain neurotoxic peptides which are responsible for the symptoms that present during envenomation by interacting with ion channels and have the potential to cause massive damage to nervous system of both vertebrates and invertebrates.

Some components in scorpion venom appear to have no other function than to cause localized pain or discomfort in the victim. By analogy with bees, which use their venom defensively,About scorpion venom these components are hypothesized to have evolved as defensive secretions. Like honey bees, the venom of some scorpions has been found to contain phospholipase A, an enzyme, and histamine, which dilates blood vessels. Related image Serotonin, which causes constriction of blood vessels in mammals, is also produced by some scorpions and has been suggested as a pain-producing compound (seratonin in insects increases muscle excitation). Other researchers have found that serotonin in the scorpion’s venom induces uterine contractions and causes spontaneous abortions in rats. They suggest that serotonin is responsible for spontaneous abortions in women who are stung by scorpions in their first trimester.
