Figure 27 in A salticid archetype for salticid spiders

Figure 27. Faces. We readily recognize salticids by the presence of a row of large anterior eyes (1-2), but also respond to the faces of our primate relatives (3-6). Facial expressions of primates are versatile, but salticids may also communicate through positions and movement of pedipalps and chelicerae, sometimes concealing the latter with the former.
