Abudefduf Explained

Abudefduf, also known as the sergeant-majors, is a genus of fish in the family Pomacentridae. The name is from Arabic abu, "the one with"; and def, "side", and the intensive plural ending -duf. The name thus means "the one with prominent sides".^[1]

General biology

The approximately 20 species of Abudefduf may be divided into planktivores and benthivores and three broadly pantropical clades.^{[2] [3] [4]} Two of the Abudefduf clades are primarily benthivorous and a third clade is composed of planktivores and is the most species-rich. Most diversification has occurred in the last 10 million years within this genus across all clades.^{[5] [6]}
