Basic arrangement of spider eyes, viewed from above. Most spiders have eight eyes, which tend to be arranged into two rows of four eyes on the head region. The eyes can be categorised by their location and are divided into the anterior median eyes (AME), anterior lateral eyes (ALE), posterior median eyes (PME), and posterior lateral eyes (PLE).
"Squared-off" cephalothorax and eye pattern of jumping spiders. Although other spiders can also jump, salticids including Portia fimbriata have significantly better vision than other spiders, [12]: 521 [13] and their main eyes are more acute in daylight than a cat's and 10 times more acute than a dragonfly's.

Eye pattern of jumping spiders on "squared-off" cephalothorax. Jumping spiders have eight eyes, the two large ones in the centre-and-front position (the anterior-median eyes, also called "principal eyes" [6]: 51 ) providing acute vision and housed in tubes in the head. The other six are secondary eyes, positioned along the sides of the carapace ...
Jumping spider. What they look like: There are more than 300 species of these, and they all look a little different. “Their colors can vary from solid black with distinctive markings, to striped ...
Lyssomanes is a spider genus of the family Salticidae (jumping spiders), ranging from South and Central America, up to the southern United States. [1]There have been described 94 extant and two fossil species [2] [3] from the Neotropical Region.
Chalcoscirtus lepidus is a small spider. [9] The male has a brown carapace that is typically 1.06 mm (0.04 in) long and 0.69 mm (0.03 in) wide. It has a pattern of black veins and has a sparse covering of light elongated scales. The eye field is dark brown with the area around the eyes is black. The spider's face, clypeus, is yellow-brown and ...
The jumping spiders, unlike the other families, have faces that are roughly rectangular surfaces perpendicular to their direction of motion. In effect this means that their forward-looking, anterior eyes are on "flat faces", as shown in the photographs. Their eye pattern is the clearest single identifying characteristic.
Most species in the genus Maevia follow the mating behavior of the gray morph of the M inclemens species. [5] This courtship behavior pattern is standard for all jumping spiders which involves three phases [6] In the first phase, males will utilize a mating display to attract a female's attention for the latter to identify if the male is of her species.
