Oregoniplana geniculata is a species of planarian in the family Cercyridae. [1] Its type-locality is China.
The specific epithet is derived from the Latin geniculatus, "like the bent knee", in reference to the curved penis papilla of the species. [2]
Oregoniplana geniculata can vary from having an elongate body shape to an ovate-lanceolate shape. Elongated, it is 1600–2500 μm long and 290–510 μm wide. Its dorsal surface is a brownish color over a cream-colored ground, with pigment accumulating along the body's margin and around the testes and ovaries. It has two black, semilunar eyes about 67–171 μm apart. They contain 5–6 retinal cells. Its cylindrical pharynx is in the posterior half of the body, and is about 331–399 μm long and 76–92 μm wide. The mouth opening is about a fourth of the body's length from the posterior margin. In front of the pharynx are two large testes, which are about 34–122 μm wide. The penis papilla is a long, slender cone that curves in a sharp "U"-shape. The ovaries are sickle-shaped and pear-shaped, located behind the brain. They're about 77–135 μm long and 46–58 μm wide.

Pseudunela cornuta is a species of minute sea slug, an acochlidian, a shell-less marine and temporarily brackish gastropod mollusk in the family Pseudunelidae. Adults are about 3 mm long and live in the spaces between sand grains.
Sphaerosyllis levantina is a species belonging to the phylum Annelida, a group known as the segmented worms. It was first described from Haifa Bay in the eastern Mediterranean. It is similar to Sphaerosyllis hystrix, and is thought to show a cosmopolitan distribution. Its name derives from its type locality, levantina being the feminine form of a Neo-Latin adjective meaning "pertaining to the region where the sun raises"; the adjective is feminine to agree with the feminine genus name, Syllis being a river nymph in Greek mythology.
Pseudorhabdosynochus manifestus is a diplectanid monogenean parasite first found in host Epinephelus malabaricus near Nouméa, between its secondary gill lamellae. It can infest its host by the hundreds. It was ascribed that name because it was the most abundant species found while its descriptive study was taking place. As appreciated from studying juvenile specimens, the development of female organs precedes that of male organs in this species and is likely the case in other Pseudorhabdosynochus species.
Pseudorhabdosynochus justinella is a diplectanid monogenean parasitic on the gills of the red grouper, Epinephelus morio. It has been described by Kritsky, Bakenhaster and Adams in 2015.
Pseudorhabdosynochus kritskyi is a diplectanid monogenean parasitic on the gills of the gag, Mycteroperca microlepis. The species has been described by Dyer, Williams and Bunkley-Williams in 1995 and redescribed successively by Yang, Gibson and Zeng in 2005 and by Kritsky, Bakenhaster and Adams in 2015. The name of the species honours the American parasitologist Delane C. Kritsky.
Pseudorhabdosynochus hyphessometochus is a diplectanid monogenean parasitic on the gills of the yellowmouth grouper, Mycteroperca interstitialis. It has been described by Kritsky, Bakenhaster and Adams in 2015.

Alloencotyllabe is a genus of parasitic monogenean in the family Capsalidae. It is monotypic, containing the sole species Alloencotyllabe caranxi. The specific epithet was derived from the type host of the species, which was fish belonging to the genus Caranx. It has been found from type specimens in the Persian Gulf.
Obama decidualis is a species of land planarian belonging to the subfamily Geoplaninae. It is found within Brazil.
Ototrema schildti is a species of trematode that parasitizes bats. It was described as a new species in 1978. O. schildti was first encountered in the intestine of a little brown bat in the U.S. state of Wisconsin. Little brown bats have the highest concentration of O. schildti in September and October. It can be a locally common parasite; in one population in Wisconsin, 97% of examined little brown bats were parasitized by O. schildti, with one bat containing 623 individuals.
Allobenedenia dischizosepta is a species of parasitic monogenean in the family Capsalidae. It has been found in waters off the coast of Argentina. It has been found infecting species of fish in the genus Acanthistius, such as the Argentine seabass.
