jumping spider

Description:

This is a jumping spider from the Salticidae, a family that is comprised by "...more than 500 described genera and about 5,000 described species, making it the largest family of spiders. Jumping spiders have some of the best vision among invertebrates and use it in courtship, hunting, and navigation. Though they normally move quietly and fairly slowly, most species are capable of very agile jumps, notably when hunting, but sometimes in response to sudden threats. Both their book lungs and the 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 very large anterior median eyes." http://en.wikipedia.org/wiki/Jumping_spi...
