''Polymastia'' is a genus of
sea sponges
Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through ...
containing about 30 species. These are small to large encrusting or dome-shaped sponges with a smooth surface having many teat-shaped projections (
papillae). In areas of strong wave action, this
genus does not grow the teat structures, but instead grows in a corrugated form.
