    Arizona Bark Scorpion with Scorplings – Centuroides sculpturatus

    These small bodied scorpions are most typically identified by their light brown – tan coloration, skinny metasoma (commonly called its tail) and small pedipalps (commonly called pincers). Unlike their spider cousins, they give live birth most commonly in batches of 20-30 scorplings. Although small in stature, these are the only scorpions considered to be dangerous to humans and can slide through cracks as small as 1/16 inch.

    The venom from the sting of a bark scorpion is most dangerous for children under 5 years old with the neurotoxin in their venom triggering nerves to fire without brain signaling. Clinical trials organized by the VIPER Institute showed the antivenom Anascorp to be an effective neutralizer of bark scorpion venom. (Read more at

Ingrid Peterson is a Research Technician who received her Master of Science in Applied Biosciences Professional Master’s program in the Diagnostic Laboratory Sciences track at the University of Arizona; she joined the IDRC in May 2018.  Her work has focused on human fibroblast culturing and the development of a wound assay model used to simulate the damaged dermal environment of a diabetic foot ulcer.  Using this model, and working in conjunction with another University lab, she conducts cytotoxicity studies using the antimicrobial peptide LL37 and a biomatrix gel to ascertain the morphologic and chemical impacts they might have on human fibroblast cells.
She is a born and raised Tucsonan and has always had a love for our desert plants and animals, when not in lab she can be found out hiking and taking pictures of wildlife. Her previous work includes working at Biosphere 2 in the rainforest measuring photosynthesis and CO2 uptake, as well as working in a plant sciences lab cultivating plants for pest studies. Her most recent work consisted of qualifying the toxic effects of dibutyl phthalates on the female murine reproductive system, as well as studying the toxic effects of specific bioengineered proteins on fibroblast cells in conjunction with another university laboratory.
Ingrid will be starting her PhD program Fall 2020 at the University of Arizona in Pharmacology & Toxicology under the ABBS program, she plans to go on to a job in industry post program.
