Hemimyzon taitungensis is a species of ray-finned fish in the family Balitoridae that is endemic to Taiwan. It is a small freshwater fish currently known only from running waters of the Central Mountain Range of Taiwan at high and middle elevations. In contrast to H. formosanus, it appears to be a well-defined species with no signs of strong genetic structuring suggestive of cryptic species.
Hemimyzon is a genus of freshwater ray-finned fish belonging to the family Balitoridae, the river or hillstream loaches. The species in this genus are found in eastern Asia.
The grey-faced petrel is a species of petrel endemic to the North Island of New Zealand. In New Zealand it is also known by its Māori name ōi and as a muttonbird.

Coccolepis is an extinct genus of prehistoric marine ray-finned fish in the family Coccolepididae. Originally including most species within the family, it is now restricted to two species from the Late Jurassic Solnhofen Limestone of Germany. The holotype of C. bucklandi, designated and described by Louis Agassiz, was thought to be lost but was later rediscovered in Neuchâtel.
Hemimyzon confluens is a species of ray-finned fish in the genus Hemimyzon. It is known from a single location in the Nam Ngum drainage in Laos, a tributary of the Mekong. The known material suggests a maximum standard length of about 47 mm (1.9 in). H. confluens is threatened by pollution from mining activities and hydro-power development.
Hemimyzon ecdyonuroides is a species of hillstream loach in the genus Hemimyzon. It is known from two tributaries of the Mekong, from Sekong River and Sesan River drainages in Vietnam and Laos.
Hemimyzon formosanus is a species of hillstream loach in the genus Hemimyzon. It is endemic to western portion of Central Mountain Range of Taiwan. Its maximum length is 10 cm (3.9 in). Variations in nucleotide sequences within the mitochondrial control region show strong geographic structuring suggestive of a cryptic species complex.
Hemimyzon khonensis is a species of hillstream loach in the genus Hemimyzon. It is known from a single specimen collected in the Mekong at the Khone Falls in Laos, near the Cambodian border; it is named for the falls. The specimen was 51 mm (2.0 in) in standard length.
Hemimyzon megalopseos is a species of ray-finned fish in the genus Hemimyzon.
Hemimyzon nanensis is a species of hillstream loach in the genus Hemimyzon. It occurs in the Chao Phraya basin, Thailand.
Hemimyzon pengi is a species of ray-finned fish in the genus Hemimyzon. Hemimyzon pengi is a freshwater fish, mainly found in China.
Hemimyzon papilio is a species of ray-finned fish in the genus Hemimyzon.
Hemimyzon sheni is a species of ray-finned fish in the genus Hemimyzon. It is only known from Tar-Ju River basin, Taitung County, southeast Taiwan, where its type locality is. Only three specimens were collected and later attempts to find more specimens have failed. Among its relatives, H. sheni most closely resembles H. formosanus, but it seems to be more a head-water species than H. formosanus. It is a small species with standard length of 5 cm (2.0 in).
Hemimyzon yaotanensis is a species of ray-finned fish in the genus Hemimyzon.
