General biology

The approximately 20 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.Youtube <> Creatures section, Damselfish - Author:Sublanding Fish 020-06-19/ref>
