Funnel-Web Spiders (Agelenidae)
摘要
Funnel-web spiders are a family of medium to large (up to 18 mm) spiders, with almost 1400 species in 100 genera worldwide. They are web-building animals, and their web form also gives them their English name. Their web consists of a retreat open on both sides, with its edge widening on one side to form a catching sheet, so that the whole structure resembles an open-cut funnel (Fig. 5.1). Often, the catching sheet is anchored to the side and above with hanging threads or threads in tension, depending on the possibilities offered by the surroundings.
