What is meant by the term fauna? Definition and explanation:
The term fauna comes from the Latin and derives from the name of the Roman goddess Fauna, the goddess of nature and forest. The fauna refers to the totality of all animal species occurring in a particular geographical area or habitat. Even geological eras such as chalk or Tertiary can be described in detail with regard to the fauna.
Depending on which habitat or animal groups this list of species refers to, a distinction is made between several sub-concepts of fauna. For example, biologists can speak of aqua, forest or desert fauna when describing the wildlife of their habitat. Depending on which layers or depths animals live in saline waters, the so-called marine fauna or marine fauna is divided into several subgroups. Also in terms of the individual classes of animals different terms exist within the fauna - for example, the entomofauna includes all insects of a particular region, the avifauna all bird species, the ichthyofauna all fish and the herpetofauna all amphibians and reptiles. In the case of land-living animals, the scientists also differentiate between the micro-, meio-, macro- and megafauna depending on their body size.
In contrast to the term fauna, the term flora refers to the totality of all plants.
