H. lepturus has mainly been studied to discover the components and effects of its venom, which is highly lethal and is responsible for most deaths due to scorpion sting in the Iran area.

[4] Finally, H. lepturus' phylum is Arthropoda, shared with other organisms such as insects and crustaceans, and its Kingdom is Animalia.

The next body segment included the pectines, which are a pair of comb-like structures on the ventral surface of the scorpion near the genital area.

[6] Hemiscorpius lepturus are pulmonate, utilizing book lungs, a shared characteristic among some Arachnids, including spiders.

[7] These are small hair-like structures that occur along the fixed fingers of Arachnida that detect airborne vibrations and currents, as well as electrical charges.

The telson vesicles of mature H. lepturus males are elongated compared to adult females and other species, and have two distal lobes at the base of the stinger.

[citation needed] The venom of H. lepturus is highly cytotoxic and hemolytic, meaning it is especially destructive to living blood cells.

[6] General symptoms after being stung include dry mouth, thirst, dizziness, confusion, nausea, fever, vomiting, and convulsions.

[2] Recent studies on H. lepturus venom have shown that it has inhibitory effects on the growth and reproduction of human immunodeficiency virus 1 (HIV-1).

After shedding, the scorpion's body appears colorless on the abdomen, legs, chelicerae, pedipalps, and tail.

During this time the scorpion's movement is slow and limited, and it does not drive its telson to sting at prey because of the soft state of the body.

Melanization, or re-coloration of the body, takes between ten and thirty days, and the new cuticle formed is again a yellowish/brown color.

During delivery, the space between the carapace and the abdomen is contracted so the genital opening and pectines are in position to give birth.

[citation needed] Hemiscorpius lepturus is found in warm, humid climates, typically in the Middle East.

[3] H. lepturus live in tight rock crevices and cracks to protect them from predators like centipedes, emerging to ambush prey like spiders and other insects.
