I don't understand?

Answer 2

porifera:-Sponges, the members of the phylum Porifera, are a basal Metazoa clade as a sister of the Diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells

Coelenterata:-Coelenterata is a term encompassing the animal phyla Cnidaria and Ctenophora. The name comes from Ancient Greek: κοῖλος, romanized: koilos, lit. 'hollow' and ἔντερον, enteron, 'intestine', referring to the hollow body cavity common to these two phyla.

ctenophora:-Ctenophora comprise a phylum of invertebrate animals that live in marine waters worldwide. They are notable for the groups of cilia they use for swimming, and they are the largest animals to swim with the help of cilia. Depending on the species, adult ctenophores range from a few millimeters to 1.5 m in size.

platyhelminthes:-The flatworms, flat worms, Platyhelminthes, Plathelminthes, or platyhelminths are a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates.

aschelminthes:-The Aschelminthes, closely associated with the Platyhelminthes, are an obsolete phylum of pseudocoelomate and other similar animals that are no longer considered closely related and have been promoted to phyla in their own right.

annelida:-Annelida is a group commonly referred to as segmented worms, and they are found worldwide from the deepest marine sediments to the soils in our city parks and yards. Through most of the 20th century Annelida was split into three major groups; Polychaeta, Oligochaeta (earthworms etc.) and Hirudinea (leeches).
