Also known as "Zimmermann's Poison Frog", ''Ranitomeya variabilis'' is a semi-arboreal species endemic to Brazil, Colombia, Ecuador, French Guiana, and Peru.<ref>Frost, Darrel R. (2015).

(17.1-18.1 mm). Adult frogs display coloration on a gradient from the snout to rear, going from yellow-green to blue-green. ''R. variabilis'' have a single nose spot with large, oval spots on their back. Their limbs are blue-green with small black spots.<ref>AmphibiaWeb 2023 Ranitomeya variabilis: Variable Poison Frog <https://amphibiaweb.org/species/6117> University of California, Berkeley, CA, USA.

The female will deposit 3-6 eggs in the axils of bromeliads. The tadpoles are transported by males to other axils where they can feed, often on eggs and tadpoles of other ''R. variabilis'', and ''Ranitomeya'' species.<ref>Brown, J. L., Twomey, E., Amezquita, A., de Souza, M. B., Caldwell, J. P., Lotters, S., von May, R., Melo-Sampaio, P. R., Mejia-Vargas, D., Perez-Pena, P., Pepper, M., Poelman, E.
