Adenomera martinezi is a type of frog that belongs to the Leptodactylidae family. This frog is special because it is found only in Brazil. Specifically, it lives in a place called Cachimbo, in the southwestern part of Pará state.
For a long time, scientists thought this frog lived in many places. But in 2013, new research showed that many of those frogs were actually a different species. That new species is now known as Adenomera saci.

What's in a Name?
The scientific name martinezi was given to honor Antonio Martínez. He was an entomologist (someone who studies insects) from Argentina. Because of this, people sometimes call this frog Martinez's tropical bullfrog.

These frogs are quite small. Adult males are about 22 to 24 millimeters long. That's less than an inch! Adult females are a bit bigger, around 26 millimeters long.
Their snout (nose area) is pointy when you look from above. From the side, it looks sharp. Male frogs have a special shovel-like ridge on the tip of their snout.
They have a visible eardrum, called a tympanum. There's also a fold of skin above it. Their finger and toe tips are rounded, but they don't have webbing like some frogs.
Colors and Sounds
The frog's back has dark spots arranged in rows. Males are moss green, and females are grayish brown. They also have a cream-colored stripe down their back. Their belly is a bright yellow color.
Male frogs have a special pouch under their throat called a vocal sac. They use this sac to make calls. Their calls are long, lasting from about 63 to 151 milliseconds. You can even hear the individual pulses in their call!
Where They Live and How We Protect Them
Adenomera martinezi lives in grassy fields. These fields are often found near rocky areas with sandy or muddy soil. Their home in Cachimbo is a mix of two different types of environments: the Cerrado and the Amazon.
Male frogs usually call after the sun goes down. They might call from inside small underground spaces. Or, they might call from out in the open, often hidden among clumps of grass.
The International Union for Conservation of Nature (IUCN) checks on how many of these frogs are left. Because this frog is only found in a very small area, it is considered a "near threatened" species. This means it could become endangered if we don't protect its home.
