The front legs of the male bears thick brushes of hairs on the metatarsi and white hairs on some other segments. The cephalothorax is brightly coloured and is ornamented with a crest of hair.

Jumping Spiders display an unusual prowess in springing on their prey and leaping away from danger. Most do not spin webs.

They can be easily recognised by their unique eye arrangement. Viewed from above, the eyes are arrranged in three rows: two pairs in front, a pair of usually tiny ones in the middle, and another pair further back: an arrangement which allows them to enjoy an almost 360 degree field of vision. Two of the four eyes in the front row (the anterior median eyes) are typically enlarged and have certain anatomical features which give the spiders a telephoto system. The lateral eyes, on the other hand, function as stereoscopic wide-angle lenses. Together, the eyes allow the spider to detect movement, recognise their prey, and judge distance accurately before they pounce for the kill.
