Microhylidae is a family of small, terrestrial frogs found in many diverse habitats across the world. They are commonly referred to as narrow-mouthed frogs or micro-frogs due to their small mouths and diminutive size. Other synonyms for Microhylidae include micro frog, pigmy frog, and tiny frog. These amphibians have adapted to living in a wide range of environments such as forests, grasslands, and even deserts. They are known for their distinctive calls - chirps, whistles, and trills, which are often heard during the breeding season. Despite their size, many species of Microhylidae are important predators of insects and other small invertebrates, making them an important part of many ecosystems.
