Habitat & Geographic Range

Canadian beaver

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

Range

Found in Venezuela.

Canadian beaver

The largest rodent in North America, Canadian beavers weigh up to 32 kg and are master ecosystem engineers inhabiting rivers, lakes, and wetlands across Canada and the northern United States. By felling trees and constructing dams up to hundreds of meters long, beavers create ponds that provide habitat for hundreds of species. Their lodges and canals transform entire watersheds. Once nearly hunted to extinction for their fur, beaver populations have recovered strongly.

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.
