Bagrus

Bagrus is a genus of bagrid catfishes. These are relatively large catfished found in freshwater habitats in Africa,[1] except for the virtually unknown B. tucumanus from South America, which likely is a synonym of Luciopimelodus pati.[2][3]

Taxonomy

The present scientific name Bagrus was first proposed by Louis Augustin Guillaume Bosc in 1816 for the bayad and its closest relatives. Although in 1809, Geoffroy Saint-Hilaire had already separated this fish in his new genus Porcus. But this was overruled by the ICZN, so that the junior synonym could continue to be used.[4]

Species

Eleven living species are placed here:[1]

A possible fossil Bagrus from about 7 million years ago, found in Late Miocene Baynunah Formation[5] rocks near Ruwais (Abu Dhabi), has been described:[4]

  • Bagrus shuwaiensis Forey & Young, 1999

However, it is not quite clear whether it belongs in Bagrus or some other Bagridae genus, or even in the Claroteidae.[4]

gollark: Well, it's good if 1e6/n - (equivalent monetary cost of dying)/n > 0. Multiply both sides by n and it's trivial.
gollark: 1e6 = 1 million.
gollark: The expected value is 1e6/n - (equivalent monetary cost of dying)/n. So whether it is a good choice depends on whether (equivalent monetary cost of dying is greater than 1e6 euros, which is no.
gollark: I mean, the compress CLI thing, it works fine apart from that.
gollark: Muahahaha. Now I just need to implement "compress", and also any incremental compression whatsoever.
