Abstract

The world has been divided into the following faunal regions: (1) Ethiopian — most of Africa; (2) Oriental — tropical Asia and closely associated islands; (3) Paleartic — Eurasia above the tropics and northernmost Africa; (4) Neartic — North America; (5) Australia — Australia, New Zealand, New Guinea, Tasmania and a few smaller islands; (6) Neotropical — South and Central America. The Neotropical Region, containing the greatest diversity of freshwater fish fauna, is subdivided into eight regions including the Amazonian region. Located at the heart of this richness is the Amazon basin.
