Jumping spiders, also known as Salticidae, also called Charlies, Salties or Herbies, actually do more of a dance than a jump, according to scientists. Plus, the name “Salticidae” is Latin for “dancing with pantomimic gestures.” These guys are active during the daytime, unlike most of its cousins, and they like to warm themselves in the sun. They’re usually black in color and have thick, short legs. Jumping spiders are known to have the best vision of any arachnid. They like to build their web retreats under furniture, in floor cracks and around windows and doors.
