The white-cheeked pintail, also known as the Bahama pintail or summer duck, is a species of dabbling duck. It was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae under its current scientific name.
The Dreissenidae are a family of small freshwater mussels, aquatic bivalve molluscs. They attach themselves to stones or to any other hard surface using a byssus. The shells of these bivalves are shaped somewhat like those of true mussels, and they also attach themselves to a hard substrate using a byssus, however this group is not at all closely related to true mussels, being more closely related to the venus clams (Veneridae).
Unio is a genus of medium-sized freshwater mussels, aquatic bivalve mollusks in the family Unionidae, the river mussels. They are found throughout Europe, Africa, and the Middle East, with some species introduced to East Asia. Fossil species are also known from the Jurassic of North America.
Hungerfordia is a genus of small land snails with an operculum, a terrestrial gastropod mollusk in the family Diplommatinidae endemic to the Republic of Palau. Many of the members of this genus inhabit limestone cliffs or rubble, especially in the Rock Islands (Chelbacheb) in Airai, Koror, and Peleliu states. As of 2022, there are 41 described species in this genus. A series of revisions in 2013 - 2015 described several new species, as well as transferring Palauan members of the genus Diplommatina or Palaina into Hungerfordia.
Euconulidae is a taxonomic family of minute, air-breathing land snails, terrestrial pulmonate gastropod mollusks or micromollusks in the superfamily Trochomorphoidea.
Columbarium is a genus of deepwater sea snails, marine gastropod molluscs in the family Turbinellidae, the pagoda shells.
Phos tsokobuntodis is a species of small sea snail, a marine gastropod mollusk in the family Buccinidae, the true whelks
Fulgurofusus is a genus of sea snails in the family Columbariidae.
Histricosceptrum is a genus of sea snails, marine gastropod mollusks in the family Turbinellidae.
Carolesia blakei is a species of sea snail, a marine gastropod mollusk in the family Tegulidae.
Ministrymon azia, the gray ministreak, is a butterfly in the family Lycaenidae. It is found from the southern United States to southern Brazil, Paraguay and Argentina. It is found in virtually all lowland habitats, ranging from deserts in coastal Peru and Chile to rainforests in the Amazon basin.
Ambigolimax is a genus of air-breathing land slugs in the family Limacidae, the keelback slugs. There is still ongoing disagreement whether it is more appropriate to consider Ambigolimax as merely a subgenus of Lehmannia; the evidence for splitting them is phylogenetic trees constructed on the basis of DNA sequences.
The name Ambigolimax nyctelius has been used to refer to several species of air-breathing land slugs in the family Limacidae. An article published in 2022 revealed this confusion and furthermore showed that the original description applied to a slug species in a different family. The above names are therefore no longer appropriate and care is need to interpret the meaning of earlier usages.
Eupera is a genus of bivalves belonging to the family Sphaeriidae.
Eupera trolobia is a species of mollusc that lives in caves. The discovery of E. troglobia makes it the first troglobitic bivalve from the Americas. The holotype collected was named holotype MZSP 155717 and the paratype MZSP 155716. All were discovered in eastern subterranean Brazil at Casa Pedra cave 10°49'28.4''S, 49°37'16.5''W. Records of the species date back to 2006 in the technical report of Brazil's National Center of Cave Exploration and Conservation.
Eupera yucatanensis is a species of mollusc that lives in fresh water. E. yucatanensis has one subspecies, E. y. minima. The description of E. yucatanensis was not documented. The species status is uncertain due to the undocumentation of the species. The subspecies is also uncertain. The subspecies was discovered in 1920 by Pilsbry.
Eupera guaraniana is a species of freshwater mollusk inhabiting the Uruguay River in South America. The species was discovered in 1994 by Cristián Ituarte.
Lehmannia carpatica is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusc in the family Limacidae.
Ambleminae is a subfamily of freshwater mussel in the family Unionidae. They are found throughout much of eastern North America south to Central America, although fossils are also known from Siberia. Some species have also been introduced to East Asia. They are the most speciose radiation of the Unionidae, with more than 300 species.
Pyramidella ovata is a species of sea snail, a marine gastropod mollusk in the family Pyramidellidae.
