Most spiders possess eight (yes, 8!) eyes, though the majority cannot see very well with them. Web-spinning spiders are nearly blind, navigating their world mostly by touch and smell. Some spiders, such as those in the family Sicariidae, have only six eyes. Cave-dwelling species, and those which live their entire lives in the soil, may have no eyes at all. There are also some spiders that fall between these extremes, but always with an even number of eyes. Those spiders which hunt their prey “on foot” can have very keen eyesight. Among those sharp-eyed hunters are the jumping spiders (family Salticidae) and the wolf spiders (family Lycosidae), both of which have at least one pair of very large, forward-facing eyes.
