Fig. 3

Embryonic comparison between two nocturnal gekkonids: potentially heliothermic, cryptic Gekko kuhli and thigmothermic, non-cryptic Lepidodactylus lugubris. Note the early accumulation of dorsal and craniofacial pigment in G. kuhli while none is visible in L. lugubris. Row a Lateral view of whole G. kuhli embryos, stages 29–36. Row b Lateral view of G. kuhli embryos craniofacial region, stages 29–33. Row c Lateral view of G. kuhli embryos craniofacial region, stages 34–36. Row d Lateral view of whole L. lugubris embryos, stages 29–36. Row e Lateral view of L. lugubris embryos craniofacial region, stages 29–33. Row f Lateral view of L. lugubris embryos craniofacial region, stages 34–36. White arrows indicate area of pigment accumulation. Scale bars = 2 mm
