and over 6000 described species,making it the largest family of spiders at 13%
of all species. –Wikipedia
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. Both their book lungs and tracheal system are
well-developed, and they use both systems (bimodal breathing). Jumping spiders
are generally recognized by their eye pattern. All jumping spiders have four pairs
of eyes, with the anterior median pair being particularly large.
Although jumping spiders are generally carnivorous, many
species have been known to include nectar in their diets. Jumping spiders
conduct complex, visual courtship displays using both movements and physical
bodily attributes. Unlike females, males possess plumose hairs, colored or iridescent
hairs, front leg fringes, structures on other legs, and other, often bizarre,
modifications. These characteristics are used in a courtship "dance"
in which the colored or iridescent parts of the body are displayed. In addition
to the display of colors, jumping spiders perform complex sliding, vibrational,
or zigzag movements to attract females.
