Encyclopedia
Polymastia is a genus of sponges (Porifera) 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.
