The mystery of how spiders extract food without masticating prey
Standard accounts of how spiders obtain food without masticating their prey are probably largely wrong. Species in the families Uloboridae, Thomisidae, Araneidae and Theridiidae do not inject digestive fluid into the prey’s ...
Feeding by Philoponella vicina (Araneae, Uloboridae) and how uloborid spiders lost their venom glands
Feeding by uloborid spiders is unusual in several respects: cheliceral venom glands are absent; prey wrapping is extensive (up to several hundred metres of silk line) and severely compresses the prey; the spider’s mouthparts ...
Tie them up tight: wrapping by Philoponella vicinaspiders breaks, compresses and sometimes kills their prey
We show that uloborid spiders, which lack the poison glands typical of nearly all other spiders, employ thousands of wrapping movements with their hind legs and up to hundreds of meters of silk line to make a shroud that ...
Snake venomics of Bothrops punctatus, a semi-arboreal pitviper species from Antioquia, Colombia
(PeerJ 2:e246, 2014-01-22)
Bothrops punctatus is an endangered, semi-arboreal pitviper species distributed in Panam´a, Colombia, and Ecuador, whose venom is poorly characterized. In the present work, the protein composition of this venom was ...
Novel catalytically-inactive PII metalloproteinases from a viperid snake venom with substitutions in the canonical zinc-binding motif
Snake venom metalloproteinases (SVMPs) play key biological roles in prey immobilization and digestion. The majority of these activities depend on the hydrolysis of relevant protein substrates in the tissues. Hereby, we ...
Amino acid sequence and biological characterization of BlatPLA2, a non-toxic acidic phospholipase A2 from the venom of the arboreal snake Bothriechis lateralis from Costa Rica
Bothriechis is considered a monophyletic, basal genus of arboreal Neotropical pitvipers distributed across Middle America. The four species found in Costa Rica (B. lateralis, B. schlegeli, B. nigroviridis, B. supraciliaris) ...
