Yellow-bellied poison frog - size reference, Uraba, Colombia
After a very rocky road we arrived in the Cotton-top Tamarin reserve, Uraba, Colombia. One of the most beautiful and pristine forests we've yet seen, but very hard to navigate as the terrain is extremely muddy and steep, and progress is slow.
One highlight we did find is this small yet beautiful poison frog, most commonly named the yellow-bellied poison frog. It's only about 0.5 inch in size, here's a macro from the side:

The yellow-bellied poison frog, yellow-bellied poison-arrow frog, or yellowbelly poison frog (Andinobates fulguritus) is a species of frog in the family Dendrobatidae. It is found in northwestern Colombia (Chocó Department and the westernmost Antioquia and Risaralda) and east-central Panama.
