Rapid prey manipulation and bite location preferences in three species of wandering spiders.

Predator-prey interactions are the interspecific relationships of greatest interest in ecology. Spiders are among the most diverse and ubiquitous terrestrial predators on the planet. Their large dietary breadth is often linked with the development of specific predatory behaviors and morphological adaptations.

Pinching or stinging? Comparing prey capture among scorpions with contrasting morphologies.

Background: Scorpions can use their pincers and/or stingers to subdue and immobilize their prey. A scorpion can thus choose between strategies involving force or venom, or both, depending on what is required to subdue its prey. Scorpions vary greatly in the size and strength of their pincers, and in the efficacy of their venom.

Prey and Venom Efficacy of Male and Female Wandering Spider, (Araneae: Ctenidae).

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 which different toxins seem to target different types of prey. In this study, we focused on the trophic ecology and venom toxicity of F.

A new species in the troglomorphic scorpion genus from Colombia, representing the northernmost known record for the genus (Scorpiones, Troglotayosicidae).

We describe a new scorpion species in the troglomorphic genus Troglotayosicus Lourenço, 1981 from Colombia. Troglotayosicus meijdeni sp. nov.
