Does a tarantula spider have more than 2 eyes?

Tarantulas have 8 eyes. A pair of 'main' eyes

looks forward. It has 3 more pairs, all smaller than the main pair,

spaced around its 'head.' Most tarantulas have pretty much full

coverage all around them; some seem to have a small blind spot

directly down the back center line. It takes very little movement

of the head to cover that spot, when it exists. They have compound

eyes, making them very good at detecting motion and using light

sources for finding directions (navigating). It seems they have

good binocular vision (direct depth perception) in front, quite a

bit weaker on the sides and back.
