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 …

Scorpions possess two systems of weapons: the pincers (chelae) and the stinger (telson).
These are placed on anatomically and developmentally well separated parts of the body …

Scorpionism is a global health concern, with an estimation of over one million annual
envenomation cases. Despite this, little is known regarding the drivers of scorpion venom …

Scorpions are a group of arachnids with great evolutionary success that comprise more than
2,000 described species. Mitochondrial genomes have been little studied in this clade. We …

Spiders rely on venom to catch prey and few species are even capable of capturing
vertebrates. The majority of spiders are generalist predators, possessing complex venom, in …

Predators, such as spiders, may modulate their predatory behavior according to the
defensive mechanisms of their prey. This study analyzed the prey capture behavior of …
