Mesotardigrada is one of three classes of tardigrades, consisting of a single species, Thermozodium esakii. The animal reportedly has six claws of equal length at each foot. This species was described in 1937 by German zoologist Gilbert Rahm from a hot spring near Nagasaki, Japan. The inability of taxonomists to replicate Rahm's finding has cast doubt on the accuracy of the description, making T. esakii, and by extension the entire class Mesotardigrada, a taxon inquirendum.
The Pedetidae are a family of mammals from the rodent order. The two living species, the springhares, are distributed throughout much of southern Africa and also around Kenya, Tanzania, and Uganda. Fossils have been found as far north as Turkey. Together with the anomalures and zenkerella, Pedetidae forms the suborder Anomaluromorpha. The fossil genus Parapedetes is also related.
Aaadonta is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Endodontidae. Specimens from this genus are endemic to Palau.
Aaadonta pelewana is a species of snail, a terrestrial pulmonate gastropod mollusk in the family Endodontidae. It is found in Palau, where it was known from Peleliu and Koror. If it is still extant, it is threatened by the destruction and modification of its tropical moist lowland forest habitat.
Epomophorus is a genus of bat in the family Pteropodidae. They have a distribution throughout Africa.
Aacocrinus is a genus of extinct sea lily from the Actinocrinitidae family. There are currently 14 species within this genus:
Aades is a genus of beetles in the family Curculionidae, commonly known as weevils. These insects are found in various parts of the world, including North and South America, Asia, and Europe. They are generally small in size, with most species measuring between 2 and 7 millimeters in length.
Akera bullata, named the royal flush sea slug, is a species of sea snail, a marine opisthobranch gastropod mollusk in the family Akeridae, a family that is related to the sea hares. This species is the only European representative of the genus Akera.
Aagaardia is a genus of fly in the Chironomidae family. Aagaardia has been found in Finland, the mainland of Norway and Russia.
Aaglacrinus is an extinct genus of crinoidea in the Cladia order. It has been proposed that it was a stationary (attached) suspension feeder the hard parts of which were composed of magnesium calcite.
Aglaocrinus is an extinct species of crinoids in the Cladia order. It has been proposed that it was a blind, stationary (attached) suspension feeder the hard parts of which were composed of magnesium calcite. It has been discovered in 3 locations in North America.
Anagyrus is a large genus of parasitic wasps from the family Encyrtidae. Anagyrus is distributed throughout the world. A subgenus of Anagyrus is known as Nesoanagyrus
Asida is a large genus of darkling beetles. They have been located around western Europe, in particular near the Mediterranean Sea.
Chodsigoa is a genus of shrews in the tribe Nectogalini.
Van Sung's shrew, also known as Cao Van Sung mountain shrew is a species of shrew in the Soricomorpha order. Specimens of Chodsigoa caovansunga have been found in Vietnam.
Episoriculus is a genus of shrew in the red-toothed shrew subfamily. Its common is brown-toothed shrew. It has been described as a subgenus to Soriculus in the past. The genus occurs at a number of locations in Asia, including Nepal and China.
The Taiwanese brown-toothed shrew is a species of shrew in the tribe Nectogalini. It is found only in Taiwan. It prefers dense ground cover in forests and subalpine shrublands in high mountains of central Taiwan. Its placement in Episoriculus has been questioned, with genetic analysis finding that it is more basal within Nectogalini than other members of Episoriculus.
Agriotes is a genus of beetles in the family Elateridae which includes numerous species, many of which are found in the Americas, Asia and much of Europe.
Aaka is a genus of hemiptera in the leafhopper family. There is only one species described in this genus, known as Aaka coera. It is distributed in Papua New Guinea.
