A Cocktail of Neurotoxins
The venom contains many small peptides that act on sodium and potassium channels in nerves, causing intense pain and in severe cases heart and respiratory failure, mostly in children and the elderly. Antivenom is available.
Chlorotoxin and Tumor Paint
A venom peptide called chlorotoxin binds to cells of glioma, a deadly brain cancer. A fluorescent version of the peptide, called tumor paint, has been tested to make tumors glow during surgery. See Cancer.
Desert Dweller
The scorpion lives in deserts and scrub and glows under ultraviolet light. See Arizona Bark Scorpion.
