An unusually complex venom system in araneophagous palp-footed spiders (Palpimanidae)

  An unusually complex venom system in araneophagous palp-footed spiders (Palpimanidae) Venoms are key adaptive traits in many animal lineages, yet their structural and functional diversity in spiders remains poorly investigated. Here, we present an initial characterization of the venom system of palp-footed spiders (Palpimanidae), a family specialized in hunting other spiders. Using micro-computed tomography, we found that the venom glands of the single species examined, Palpimanus gibbulus , exhibit a complex, multi-lobed morphology that is unusual among araneomorph spiders. Proteo-transcriptomic analyses of two Palpimanus venoms ( P. gibbulus and P. cyprius ) revealed highly diverse putative toxin repertoires comprising hundreds of peptides and proteins, including numerous novel putative neurotoxins, cytotoxins, enzymes, and allergens. Five major families of cysteine-rich palpitoxins were identified as the dominant putative neurotoxic components in both species, displaying con...

The Zoological Survey of India (ZSI) was established on 1st July, 1916 to promote survey, exploration and research leading to the advancement in our knowledge of various aspects of exceptionally rich life of the erstwhile ´British Indian Empire´. The survey has its genesis in the establishment of the Zoological Section of the Indian Museum at Calcutta in 1875. By gradually strengthening its staff and expanding its research programme, the Survey has met the challenge of the past and is on its way to meet the demands of the future. It has maintained its primary objectives unchanged from its inception.
