Hogna wolf spider (family Lycosidae) showing the enlarged posterior median eyes typical of the family. The eyes of spiders vary significantly in their structure, arrangement, and function. They usually have eight, each being a simple eye with a single lens rather than multiple units as in the compound eyes of insects. The specific arrangement ...
The main pair of eyes in jumping spiders even sees in color. [9] Net-casting spiders of genus Deinopis have their posterior median eyes enlarged into large forward-facing compound lenses. These eyes have a wide field of view and are able to gather available light more efficiently than the eyes of cats and owls.
The many genera of wolf spiders range in body size (legs not included) from less than 10 to 35 mm (0.4 to 1.38 in). [1] [2] They have eight eyes arranged in three rows. The bottom row consists of four small eyes, the middle row has two very large eyes (which distinguishes them from the Pisauridae), and the top row has two medium-sized eyes ...

It has eight eyes, eight legs covered in “golden” hair and “long” “fringe” on its face. Photos show the new species. It has a dark brown body and almost looks like it’s wearing ...
The time-counted tarantula can reach about 1.2 inches in length, researchers said. It has eight eyes, eight legs and is covered with “bright golden,” “long” hairs. Photos show the new species.
This spider can be identified by its large size and distinctive markings. It has eight eyes with good vision, and its body is grey to brown. They have a white to a pale cream colored stripe running down each side of the cephalothorax. The abdomen has many light colored spots and also has light colored lines running down the sides of the abdomen.
In web-building spiders, all these mechanical and chemical sensors are more important than the eyes, while the eyes are most important to spiders that hunt actively. [ 13 ] Like most arthropods, spiders lack balance and acceleration sensors and rely on their eyes to tell them which way is up.
