People and other animals have always adapted spider silk to their own purposes. Here's a spectacular piece of footage from Jeremy Wade's Animal Planet "River Monsters" series showing a skillful South Pacific fisherman using Nephila, or golden orb weaver, silk as an all-in-one tool. Notice the golden hue of the silk, and just how stuck into the tangled silk the fish gets. I wonder whether the aggregate silk protein glue that lies along the web's capture spiral survives its swish through the salt water and that's what the fish sticks to, or whether the fish simply gets major ampullate and flagelliform silk wound around its teeth. Thanks to Green Matter for the tip.
