Family-Animalia: Pomacentridae

Pomacentridae is a family of ray-finned fish, comprising the damselfishes and clownfishes. This family were formerly placed in the order Perciformes but are now regarded as being incertae sedis in the subseries Ovalentaria in the clade Percomorpha. They are primarily marine, while a few species inhabit freshwater and brackish environments (e.g., Neopomacentrus aquadulcis, N. taeniurus, Pomacentrus taeniometopon, Stegastes otophorus). They are noted for their hardy constitutions and territoriality. Many are brightly colored, so they are popular in aquaria.

Around 385 species are classified in this family, in about 29 genera. Of these, members of two genera, Amphiprion and Premnas (subfamily Amphiprioninae), are commonly called clownfish or anemonefish, while members of other genera (e.g., Pomacentrus) are commonly called damselfish. The members of this family are classified in four subfamilies: Amphiprioninae, Chrominae, Lepidozyginae, and Pomacentrinae.
