👉 The term "phoenicopteroideae" is a generic name for a group of protostomes. Protostomes are a type of single-celled eukaryotic cells that form the basis of all multicellular organisms on Earth, including bacteria and fungi. They include small, round-shaped organisms called phoebeids. The specific phoenicopteroideae is not typically recognized by scientists or researchers, but it has been proposed for inclusion in the classification of protostomes.
