Darko Cotoras An island spider decides which of its three kinds of webs to make depending on location and perhaps individual preferences. Spiders usually make only one kind of web, but the Wendilgarda galapagensis spider – which lives exclusively on Cocos Island, about 550 kilometres off the western coast of Central America – can make three different webs. Advertisement High above ground it makes “aerial” webs attached to nearby stems and leaves. Nearer to the ground it makes “land” webs with long horizontal strands secured between branches and with a series of vertical strands anchored to the ground. Finally, over pools it makes “water” webs that are a bit like the land webs, but with the vertical strands attached to the water surface itself.
