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 ...
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.

Like other jumping spiders, T. planiceps relies on their very acute eyesight for hunting. The anterior median eyes are the primary eyes used for capture of stationary prey while the anterior lateral eyes are the main eyes used in chasing Both sets of eyes can be coordinated to enable switching from one hunting type to the other.
