6 amphibians that you can find in the Amazon jungle


Welcome to another of our posts about the Amazon jungle, known as the green lung of the planet, an amazing ecosystem full of life. Did you know that among the rich biodiversity it houses, amphibians occupy a prominent place? That's right, these fascinating beings adapted to life both on land and in water, display an incredible variety of shapes and colors.

From striking poison dart frogs to curious tree frogs, the Amazon rainforest is home to a wide range of unique species with their extraordinary adaptations and important role in ecological balance.

Join us on this adventure and learn more about these fascinating animals and species.

Allobates femoralis

We begin this tour talking about The Allobates femoralis commonly known as the yellow-legged poison dart frog located further towards the Napo, Sucumbíos, Orellana and Pastaza basins in Ecuador.

Description of Allobates femoralis

It is a species of poisonous frog that is found in South America, specifically in the Ecuadorian Amazon region and presents a striking and distinctive physical appearance with a relatively small and compact body, its length varies between 2.5 and 3.5 centimeters. Its fur is smooth and shiny and it can display a variety of colors and patterns although it is known for having bright yellow feet.

It is worth mentioning that these frogs are found in rainforest habitats where they prefer to live in areas near bodies of water such as streams and streams. They are especially common in the leaf litter and undergrowth of the forest, where they camouflage themselves and protect themselves from predators.

A distinctive feature of the Allobates femoralis is its toxicity as part of its defense system, these frogs secrete toxic chemicals through their skin and these toxins are used to deter predators and warn them of their danger. Importantly, these poison dart frogs gain their toxicity through their diet and environment, so captive-bred populations fed a different diet cannot be poisonous.

Feeding and diet of Allobates femoralis

On the other hand, The Allobates femoralis is mainly insectivorous and feeds on a variety of small invertebrates and its diet consists of spiders, beetles, ants, termites and other small invertebrates present in its environment.

Allobates marchesianus | Nanny Del Vaupes Toad
