Etymology: Salticidae is the scientific name for the family of jumping spiders, and it was coined in the 19th century from a Latin-based root rather than by any ancient writer. The core is "saltus," Latin for "a leap" or "a jump," which also gives English "saltation" and "somersault" (via Old Provençal "sobresalt"). The family name was built by adding the standard zoological suffix "-idae," which marks taxonomic families, to the genus "Salticus," itself a Latinized form of "saltus." The name therefore describes the spiders' most visible habit, leaping, and the same logic produced the names of many other animal families. Because scientists in that period drew on classical Latin to create names that anyone studying animals could read, a Greek or Roman naturalist would not have recognized the term, even though the root meaning was familiar to them.
