The family Atypidae, commonly known as purse-web spiders, belongs to the order Araneae. These spiders are primitive mygalomorphs, closely related to tarantulas, and are characterized by their stout bodies and long, downward-pointing fangs. Atypids are known for constructing distinctive tubular silk webs, often attached to the ground or tree trunks, which they use to ambush prey. They feed primarily on insects and other small arthropods, detecting vibrations on the web before piercing it to capture their victims. Found in parts of North America, Europe, and Asia, Atypidae are secretive, slow-moving spiders that spend most of their lives within or near their webs, making them an intriguing but rarely seen component of their ecosystems.
