Venom Costs and Optimization in Scorpions [PDF]

open access: yesFrontiers in Ecology and Evolution, 2019
Scorpions use venoms as weapons to improve prey capture and predator defense, and these benefits must be balanced against costs associated with its use. Venom costs involve direct energetic costs associated with the production and storage of toxins, and indirect fitness costs arising from reduced venom availability.

The envenomation of general physiology throughout the last century. [PDF]

open access: yes, 2017
Toxins are the poisonous products of organisms. Toxins serve vital defensive and offensive functions for those that harbor them: stinging scorpions, pesticidal plants, sanguinary snakes, fearless frogs, sliming snails, noxious newts, and smarting spiders.

Scorpion venomics: a 2019 overview

open access: yesExpert Review of Proteomics, 2019
Introduction: A few scorpions are dangerous to humans. Their medical relevance was the initial driving force for venom research. By classical biochemistry and molecular cloning, several venom peptides and their coding transcripts were characterized, mainly those related to toxins.

Spider neurotoxins targeting voltage-gated sodium channels [PDF]

open access: yes, 2005
The voltage-gated sodium (Nav) channel is a target for a number of drugs, insecticides, and neurotoxins. These bind to at least seven identified neurotoxin binding sites and either block conductance or modulate sodium channel gating and/or kinetics.

A first molecular characterization of the scorpion telson microbiota of Hadrurus arizonensis and Smeringurus mesaensis.

open access: yesPLoS ONE, 2023
Scorpions represent an ancient lineage of arachnids that have radiated across the globe and are incredibly resilient-since some thrive in harsh environments and can exist on minimal and intermittent feedings.
