Jumping spiders do sometimes bite, but their venom is not considered to be dangerous (unless youâre allergic to spider bites). They are sometimes mistaken for black widow spiders, but they are far less dangerous. Jumping spiders donât hunt using webs, but they do build a web-like nest called a retreat.
The jumping spider family (Salticidae) contains more than 500 described genera and about 5,000 described species, making it the largest family of spiders with about 13% of all species.Jumping spiders have some of the best vision among arthropods and use it in courtship, hunting, and navigation.Although they normally move unobtrusively and fairly slowly, most species are capable of very agile jumps, notably when hunting, but sometimes in response to sudden threats or crossing long gaps.hen a jumping spider is moving from place to place, and especially just before it jumps, it tethers a filament of silk (or 'dragline') to whatever it is standing on to protect itself if the jump should fail.
