ʻAno Flatworms ninoieo o non-parasitic a me ka parasitic 'ano apau loa. Ma keia noa-ola meaola i hui i loko o kekahi papa, a me ka poe e noho ana ma ka lilo ana o nā meaola, - eono. Papa 'elele Ciliated (Planaria turbellarians) e noho ana ma na moanawai o ka wai, pinepine nō Moana.

Parasitic flatworms noho i loko o ke kino o nā holoholona a me nā kānaka. ʻikepili meaola i pono hakuloli i kēia mau ana o ke ola, i mea. e. i ka sucker, a e pili ana i na paia o ka na nā loko o ka poʻe koa, a me ka Hoʻohana kino me ka mau loa-ulu helu o Hoʻohana. Ka mea, i wehewehe aku ma ka wa e kaawale aku o ka digestive'ōnaehana (koe wale no ka papa Flukes), i ke kemu māhuaola ma ke kino ma kūikawā outgrowths; anaerobic ka hanu nā (ka mea, ha i loko o ka kūpono kou oxygen ma-noa 'ia), a me ka hoʻonuiʻana (ka mea, he poe hermaphrodites).
