Frog Eyes I
One of the coolest things in nature are frog eyes, with their big bright corneas of varied colors and patterns and dark pupils. The eyes of the Green Frog (aka the "edible frog," Pelophylax esculentus or Rana esculenta) have a wonderful gold/ black mottling oval cornea. Frogs see best at distances, though pick up motion extremetly well, an obvious benefit for hunting insects. The prominent positioning of their eyes gives frogs a 180 degree view around them, useful for finding prey and detecting predators (like people who relish frog legs (cuisses de grenouille).
This wonderful specimen was in a small pond in the Jardin des Plantes, near the Muséum national d'Histoire naturelle in Paris.
