  Insights into the distribution and ecology of the funnelweb spider Macrothele calpeiana in Portugal Abstract Biodiversity surveys are critical to prevent decline and extinction of ill-/unknown species through timely conservation action. This is particularly relevant when the species are neither iconic nor flagships, therefore lessening the potential for accessing conservation means, such as in the case of the mygalomorph spider Macrothele calpeiana. The species is endemic to southern Iberia but its distribution and ecology is barely documented in Portugal. Therefore, we made a comprehensive survey throughout its estimated range in the south of the country. The species is spread unevenly and patchily throughout low mountainous terrain in south/southwest Portugal, preferably along shale/ greywacke/clay roadside banks. It seems rare in the surrounding limestone area to the south and absent from the peneplain to the north. The webs were found in groups averaging 10.0±15.2 webs/site a...

Beyond Snakes: Exploring Zootoxins in Invertebrates and Lower Vertebrates

Abstract

This review explores the diversity, biochemical mechanisms, and toxicological effects of venoms and toxins secreted by lower vertebrates and invertebrates, emphasizing their ecological roles and potential therapeutic applications. While snake venoms dominate toxicology research, ancient Ayurvedic texts have documented the medicinal uses of toxins from other animals in formulations like Agadas. This study examines the relevance of Jangam Visha (animate poison) in modern toxicology, highlighting envenomation cases in rural communities, where traditional household remedies often precede hospital visits. The review discusses neurotoxins like batrachotoxin, hemolytic toxins such as tetralysin, and insect-derived compounds like cantharidin and mastoparan. Additionally, species such as blister beetles (Mylabris spp.), scorpions (Hottentotta spp.), and wasps (Vespula spp.) are explored for their toxic components and therapeutic potential. The study also addresses ongoing challenges in toxin detection, neutralization, and antidote development. By bridging historical wisdom with contemporary scientific advancements, this review offers valuable insights for forensic, ecological, and biomedical research.
