The oldest representatives of Animalia, phyla Cnidaria (79) and Porifera (80), and all metazoans thereafter harbor species-specific microbes essential for their reciprocal survival.
Thus, Porifera seems to be the member of the ethnotaxon slime that most differentiates itself from the other elements which are also perceived and identified as slime, sharing fewer characters; but the main feature presenting by sea sponges to be allowed in this ethnotaxon is the presence of pores, or 'holes' as the interviewees have mentioned.
2009) found that the Placozoa are at the base of the metazoa, rather than the Porifera or sponges (Figure 1).
It includes bony fish (such as mackerel, tuna, anchovies, herrings, sardines, flying fish, ocean sunfish, swordfish, marlins, sailfish, barracudas), cartilaginous fish (such as blue sharks, dusky sharks, hammerhead sharks, dogfish, cat sharks, eagle rays), sea turtles, small cetaceans, pinnipeds, squid, pelagic red crab, salps, porifera, and birds.

The phylum Porifera is represented solely by disarticuled spicules scattered throughout the rock.
During an ongoing survey of California collections by myself and coworkers, with the aim of producing an updated guide to the Porifera of California, we encountered a hexactinellid sponge from southern California unknown to the region (last summarized by de Laubenfels 1932).
ANIMALIA 1,320,000 MESOZOA METAZOA 1,320,000 Porifera (sponges) 10,000 Cnidaria (hydras, jellyfish, corals, etc) 10,000 Platyhelminthes (flatworms) 20,000 Nematoda (roundworms) 25,000 Echinodermata (sea uchins, etc.
But the new species didn't fit in with any of the other subgroups, or phyla, of animals, like Chordata (animals with backbones), Arthropoda (spiders, insects, and crustaceans), and Porifera (sponges).
Recent analyses of the metazoan phylogenetic tree based on genomic sequences of representatives of different phyla place Placozoa as sister to the Eumeta-zoa, and Ctenophora and Porifera as the earliest diverging metazoan phyla (Ryan et al.
