It is found in the northwestern Colombia (Antioquia, Chocó, Córdoba, and Risaralda Departments) and Panama, possibly also in southeastern Costa Rica.

[3] Colostethus pratti is named after Antwerp Edgar Pratt, an explorer who collected the type series.

[2][5] Colostethus pratti is a small member of its genus; both males and females grow to about 24 mm (0.94 in) snout–vent length.

They are deposited on top of leaves or within plastic hiding places, primarily during a simulated wet season.

After hatching, the female transports the tadpoles to a body of water, carrying them on her back, sometimes for several days.
