It seemed possible that this surprising deviation from a general character of the Arachnida might be related to the contrast between the length of the limbs and the shortness

Bacterial Adaptation to Venom in Snakes and Arachnida [PDF]

open access: yesMicrobiology Spectrum, 2022
Notwithstanding their 3 to 5% mortality, the 2.7 million envenomation-related injuries occurring annually—predominantly across Africa, Asia, and Latin America—are also major causes of morbidity. Venom toxin-damaged tissue will develop infections in some 75% of envenomation victims, with E.

A Bio-Inspired Method for Mathematical Optimization Inspired by Arachnida Salticidade

open access: yesMathematics, 2021
This paper proposes a new meta-heuristic called Jumping Spider Optimization Algorithm (JSOA), inspired by Arachnida Salticidae hunting habits. The proposed algorithm mimics the behavior of spiders in nature and mathematically models its hunting ...

On the life expectancy of a male Chilean rose tarantula, Grammostola rosea (Walckenaer, 1837) (Araneae: Theraphosidae) reared in captivity

open access: yesRevista Chilena de Entomología, 2022
Here we present the case of a male Chilean rose tarantula Grammostola rosea (Walckenaer,1837) (Araneae: Theraphosidae) reared in captivity, whose life expectancy has been dated at 8.5 years. The specimen spent the last three as an adult. Both records are
