General biology
The approximately 20 species of Abudefduf may be divided into planktivores and benthivores and three broadly pantropical clades.[3][4][5] 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.[6][7]
In their native environment, sergeant majors are very abundant, often being one of the dominant species in a locale.[8][9][10][11] Research indicates that some Abudefduf species are undergoing range expansion towards more temperate waters in Australia.[12][13]
