Observing Amphibians and Microfauna
Peru's rich biodiversity comprises organisms that inhabit in the soil, the so-called the soil fauna. These species are predominantly invertebrates, who thrive thanks to the soil's composition, dampness and temperature. Depending on their size, these organisms can be categorized as microfauna (measuring less than 0.2 mm), mesofauna (measuring between 0.2 - 2 mm) and macrofauna (organisms larger than 2 mm).
The macrofauna includes more noticeable and visible organisms on the surface or underneath the soil. These are defined as molluscs (snails, earthworms, centipedes, millipedes, scorpions, ants, spiders and beetles, among others) and their observation and study attracts tourists and scientists with specific interests.
Invertebrates are the most common and abundant inhabitants of soil, playing an important role in the process of decomposing organic matter. They break down the vegetable and animal remains that make up the litterfall, facilitating the decomposition of the organic matter by the soil microflora.
