Habitat & Geographic Range

Common Thin-toed Frog

Habitat

Typically found in freshwater habitats, moist forests, and wetlands.

Range

Found in Venezuela.

Laysan Duck

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and Mediterranean forests and woodlands within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Belgium, France, Netherlands, Norway, and United Kingdom. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

Laysan Duck

Laysan Duck (Anas laysanensis) is classified as Critically Endangered (CR) on the IUCN Red List. Facing an extremely high risk of extinction in the wild due to severe population decline and habitat loss.
