Comments P.16 3rd paragraph: "Largest eyes—Net-casting spiders, family Deinopidae. Net-casting spiders in the genus Deinopis possess extraordinary enlarged posterior median eyes (Blest & Land, 1977), possibly the largest eyes of a spider (up to 1.4 mm in diameter, primary source). These eyes all possess large photoreceptors (20 μm wide, 110 μm long, BNID 116181), which are crucial for gathering light for nocturnal vision (see “Best nocturnal eyesight”) (Fig. 3C)."
