About the Sarayacu Robber Frog

What Does It Look Like?

Adult male Sarayacu robber frogs are quite small, measuring about 13 to 18 millimeters (that's about half an inch to three-quarters of an inch) from their nose to their bottom. Female frogs are a bit larger, measuring 18 to 22 millimeters (about three-quarters of an inch to almost an inch).

Their back is covered in small bumps, like warts. Even their eyelids have these tiny bumps! There's a clear, curved ridge that runs from their snout (nose) to their eyes.

When scientists first studied a preserved frog of this species, they noted it had a brownish-pink color. It also had tiny black dots and thin dark brown or black lines. These lines ran over the ridge near its snout and across its eardrum (called the tympanum). There was also a faint line between its eyes. The frog's belly and lower parts were mostly plain, with only a few light speckles on its throat and jaws.

Where It Lives and How It's Protected

Habitat and Lifestyle

The Sarayacu robber frog lives in both old, untouched forests (called primary forests) and forests that are growing back after being cut down (secondary forests). It also lives in forests that sometimes get flooded. These frogs are found at elevations between 330 and 570 meters (about 1,080 to 1,870 feet) above sea level.

These frogs are mostly active at night. They can be found among fallen leaves on the ground or in low plants. Sometimes, they even live in plants that grow on other plants, like certain ferns or orchids, which are called epiphytes.

Reproduction

Unlike many frogs that lay eggs that hatch into tadpoles, the Sarayacu robber frog likely has a "direct" way of reproducing. This means that instead of having a free-swimming tadpole stage, the eggs probably hatch directly into tiny froglets that look like miniature versions of the adults.

Conservation Efforts

Even though this frog is not very common, it is found across a wide area. Its main threat is the loss of its home, or habitat. This happens because of things like cutting down forests (deforestation) and developing land for farming.

Good news! The Sarayacu robber frog lives in several protected areas. These include the La Payas Nature Reserve in Colombia. In Ecuador, its home overlaps with the Limoncocha National Biological Reserve and the famous Yasuni National Park, which helps keep these frogs safe.
