Crassostrea is a genus of true oysters containing some of the most important oysters used for food. Some species in the genus have been moved to the genus Magallana.
Myxobolidae is a family of myxosporean parasites which typically infect freshwater fishes, and includes the economically significant species, Myxobolus cerebralis. They have been shown to have a complex life cycle, involving an alternate stage in an invertebrate, typically an annelid or polychaete worm.
Oedogonium is a genus of filamentous, free-living green algae, first discovered in the fresh waters of Poland 1860 by W. Hilse and later named by German scientist K. E. Hirn. The morphology of Oedogonium is unique, with an interior and exterior that function very differently from one another and change throughout its life cycle. These protists reside in freshwater ecosystems in both hemispheres and are both benthic and planktonic in nature. Forming algal patches on water's surface, they interact closely with a multitude of other algae. These filamentous cell's life cycles include both sexual and asexual reproduction, depending on life cycle stage. Although quite common, Oedogonium is difficult to identify, since key ID factors are only present during reproduction, which is an uncommon life stage among this genus. Oedogonium has been found to be important in the fixation of heavy metals in freshwater ecosystems.
Micrasterias is a unicellular green alga of the order Desmidiales. Its species vary in size reaching up to hundreds of microns.
Gastrodia, commonly known as potato orchids or as 天麻属 , is a genus of terrestrial leafless orchids in the family Orchidaceae, about ninety of which have been described.

They are native to Asia, Australia, New Zealand, central Africa, and various islands of the Indian and Pacific Oceans.
