Sponges, colonial animals in the phylum Porifera, are primitive invertebrates that are dominated by marine species. Typically, they are benthic, sessile filter feeders that are asymmetrical.
Molecular phylogeny (gene sequencing) and other characters show they belong to four kingdoms: Kingdom Plantae (e.g. chlorophytes and rhodophytes), the Kingdom Chromista (e.g. phaeophytes, dinoflagellates, diatoms), the Kingdom Protista (e.g. Euglenophytes), and the Kingdom Bacteria (cyanophytes).olecular phylogeny (gene sequencing) and other characters show they belong to three kingdoms: Kingdom Plantae (chlorophytes and rhodophytes), the Kingdom Chromista (phaeophytes), and the Kingdom Bacteria (cyanophytes).
