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, Land & Nilsson, 2012), which are crucial for gathering light for nocturnal vision (see “Best nocturnal eyesight”) (Fig. 3C)."
