Biodiversity and Taxonomy of Catfish Species in the Amazon Basin

Abstract

With the world's richest freshwater biodiversity and increasing human issues, The Amazon Basin is certainly a 
biodiversity flashpoint. A lack of data on the geographical distribution of freshwater fish species in this basin 
obstructs an inclusive knowledge of this hyper-diverse ecosystem as a whole. The Amazon Fish Initiative, an 
international partnership, prioritises closing this gap. Based on the research data, we give the most comprehensive 
distribution records for fish species in the Amazon drainage. The database includes 2,406 confirmed freshwater 
native fish species, 232,936 georeferenced records, and findings from a comprehensive species distribution survey 
involving 590 sources (including published articles, grey literature, online biodiversity databases, and scientific 
assortments from museums and academies around the world), as well as field trips conducted during the 
development. This database is a very useful data source for more research on the biodiversity, biogeography, and 
conservation of freshwater fish. Studies conclude that the trichomycterus species is one of the members of the 
catfish family. The lineage associated with this species is diverse and is responsible for its phylogenetic 
relationship with the other species members of the family. The evolution phases shown by trichomycterids species 
are influenced by certain climatic factors. It is provided at georeferenced locales (21,500 localities) and sub
drainage grains.
