Paleozoanthus reticulatus is a zoantharian anthozoan (order Zoantharia) representing a distinctive lineage that incorporates foreign material such as sand grains and sponge spicules into its mesogleal tissue, forming encrusting or semi-erect colonies in tropical to subtropical marine environments on hard substrates. Its placement within the zoantharian phylogeny has been clarified through molecular analyses. Genomic data have been generated for this species and are available in public databases, enabling comparative studies of cnidarian evolution and ecology.
