Jumping spiders are a group of spiders that constitute the family Salticidae. As of 2025, this family contained almost 700 described genera and over 6,000 described species, making it the largest family of spiders – comprising 13% of spider species. Jumping spiders have some of the best vision among arthropods — being capable of stereoptic color vision — and use sight 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 (the two front middle eyes) being particularly large.
