“The Frog with the Ruby Eyes”

This close-up was taken by Jaime Culebra of Spain. It features a female Mindo glass frog that Culebra felt compelled to photograph due to her strikingly ruby eyes. These frogs are native only to the South American country of Ecuador. And though they were recently rediscovered and spotted in the wild for the first time in decades, they’re still thought to be endangered.
