Distinct spinning patterns gain differentiated loading tolerance of silk thread anchorages in spiders with different ecology

摘要: Building behaviour in animals extends biological functions beyond bodies. Many studies have emphasized the role of behavioural programmes, physiology and extrinsic factors for structure function buildings. Structure attachments associated with animal constructions offer yet unrealized research opportunities. Spiders build a variety one- to three-dimensional structures from silk fibres. The evolution economic web shapes as key ecological success spiders has been related emergence high performance silks thread coating glues. However, anchorages widely neglected those models. Here, we show that orb-web (Araneidae) hunting (Sparassidae) use different application patterns determine robustness joint anchorages. Silk greater against loading situations, whereas their highest pull-off resistance when loaded parallel substrate along direction dragline spinning. This suggests 'printing' into attachment discs spinneret morphology was prerequisite extended space. highlights architectures.
