According to biological nomenclature, the organisms are named in terms of generic name followed by the species name. For example Homo sapiens where Homo is the genus name and sapiens is the species name. The different types of naming are

Autonym- They are the biological names which are generated automatically. They may or may not appear in print publication.

Tautonyms – It is a scientific name in which both the generic name and the species name are the same. For example Catla catla.
