Unlike their web-spinning counterparts, ground spiders’ silk glands cannot produce the specific threads needed to anchor a web to surfaces. But they are able to shoot at high volume tough and stretchy silk that can ensnare prey, even those larger than themselves. This ability allows ground spiders to actively hunt and capture prey, as opposed to waiting for their meals to get caught in a web.
