He points to examples in W. S. Bristowe's 1976 The World of Spiders detailing how spiders respond adaptively to novel conditions. For instance, a spider can eat a fly held in front of it by an experimenter, bypassing the usual step of moving toward an insect caught on its web.
Bolas: Bolas spiders are unusual orb-weaver spiders that do not spin the webs. Instead, they hunt by using a sticky 'capture blob' of silk on the end of a line, known as a ' bolas '. By swinging the bolas at flying male moths or moth flies nearby, the spider may snag its prey rather like a fisherman snagging a fish on a hook.
Desert Spider, Stegodyphus lineatus, one of the best-described species that participates in matriphagy Matriphagy is the consumption of the mother by her offspring. [1] [2] The behavior generally takes place within the first few weeks of life and has been documented in some species of insects, nematode worms, pseudoscorpions, and other arachnids as well as in caecilian amphibians.

Spiders that spin webs typically have three claws, the middle one being small; hunting spiders typically have only two claws. Since they do not have antennae, spiders use specialised and sensitive setae on their legs to pick up scent, sounds, vibrations and air currents. [6] Some spiders, such as the Australian crab spider, do not have claws.
