Common Thin-toed Frog

<em>Leptodactylus leptodactyloides</em>, the common thin-toed frog, is an amphibian in the family Leptodactylidae, primarily recorded from Venezuela and surrounding lowland regions of northern South America. It is classified as Least Concern on the IUCN Red List. This terrestrial frog typically inhabits savanna grasslands, gallery forests, and disturbed areas adjacent to wetlands, where it breeds in temporary pools and flooded grasslands during the rainy season. Like other leptodactylid frogs, males call from the water's edge to attract females, and the species produces foam nests for eggs. Diet typically consists of invertebrates including insects, spiders, and worms. The species is part of a diverse and taxonomically complex genus, and population status across its range is not precisely quantified. Biological traits such as adult body length, weight, lifespan, and clutch size remain poorly documented in comprehensive standardized scientific assessments for this species specifically. Conservation efforts benefit from broader amphibian monitoring programs across Venezuela and the surrounding region.
