DURING last year I noticed that Harvestmen (Opiliones) do not regenerate lost legs when they moult, and this summer I have determined that they do not regenerate pedipalpi either. 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

Current status of structural studies of proteins originating from Arachnida

open access: yesSystematic and Applied Acarology, 2023
Arthropods from class Arachnida constitute a large and diverse group with over 100,000 described species, and they are sources of many proteins that have a direct impact on human health.

Exploring species diversity and abundance of scorpions (Arachnida: Scorpiones) in certain regions of Khyber Pakhtunkhwa, Pakistan

open access: yesBrazilian Journal of Biology, 2022
Despite scorpion diversity has long been acknowledged, the mystery of how it develops remains unresolved. The geographical distribution, species abundance and biodiversity of scorpions fauna in Khyber Pakhtunkhwa is poorly explored with many aspects like

Bacterial Adaptation to Venom in Snakes and Arachnida

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.
