The Fluffy Hackled Orb-web Spider (Uloborus walckenaerius) is a unique, completely non-venomous cribellate spider belonging to the family Uloboridae. Named in honour of French entomologist Charles Athanase Walckenaer, this species is famous for lacking venom glands entirely. Instead, it relies on complex silk-wrapping strategies to crush and immobilise its prey.
