Colombian Swamp Frog

<em>Pseudopaludicola pusilla</em>, the Colombian swamp frog, is a small anuran amphibian in the family Leptodactylidae, distributed across Colombia and Venezuela. This species inhabits freshwater ecosystems including marshes, flooded grasslands, seasonally inundated forests, and the margins of streams and ponds within moist forest biomes. Frogs of the genus <em>Pseudopaludicola</em> are characteristically tiny and highly active, often difficult to observe directly despite their occasionally conspicuous advertisement calls during the breeding season. <em>Pseudopaludicola pusilla</em> is assessed as Least Concern by the IUCN, indicating that its populations are not currently considered at significant risk of decline across its range. As a small insectivore, this species feeds primarily on ants, mites, and other minute invertebrates, and serves as prey for a range of predatory vertebrates inhabiting its wetland and forest edge habitats. Seasonal flooding patterns strongly influence its reproductive activity and habitat availability. Biological traits of this species remain poorly documented in the scientific literature.

Polar bear
