Abudefduf - Sergeant-majors
Description
Abudefduf also known as the sergeant-majors is a genus of fish in the family Pomacentridae.
The 21 species of Abudefduf may be divided into planktivores and benthivores and three broadly pantropical clades. 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.
