Members of the family acquired the name "spider-crab" due to the manner of movement: they do not walk head first, but sideways. Like crabs, they can move sideways and backward.
They are found mainly in North America, but sometimes in the southern part of Europe and Asia.
They do not weave cobwebs, but usually hunt on the ground, hiding among vegetation, such as flowers.
Spiders have a flat body, they live under stones and on walls. Spiders are pretty agile and not easy to catch. Their disguise helps them not to be evident, therefore it is rather difficult to notice them on walls or stones.
