The Elopiformes are the order of ray-finned fish including the tarpons, tenpounders, and ladyfish, as well as a number of extinct types. They have a long fossil record, easily distinguished from other fishes by the presence of an additional set of bones in the throat.
Johann Friedrich von Brandt was a German-Russian naturalist, who worked mostly in Russia.
Pygmy geese are a group of very small "perching ducks" in the genus Nettapus which breed in the Old World tropics. They are the smallest of all wildfowl. As the "perching ducks" are a paraphyletic group, they need to be placed elsewhere. The initially assumed relationship with the dabbling duck subfamily Anatinae has been questioned, and it appears they form a lineage in an ancient Gondwanan radiation of waterfowl, within which they are of unclear affinities. An undescribed fossil species from the late Hemphillian of Jalisco, central Mexico, has also been identified from the distal end of a tarsometatarsus. It is only record of the genus in the New World.
King crabs are decapod crustaceans of the family Lithodidae that are chiefly found in deep waters and are adapted to cold environments. They are composed of two subfamilies: Lithodinae, which tend to inhabit deep waters, are globally distributed, and comprise the majority of the family's species diversity; and Hapalogastrinae, which are endemic to the North Pacific and inhabit exclusively shallow waters. King crabs superficially resemble true crabs but are generally understood to be closest to the pagurid hermit crabs. This placement of king crabs among the hermit crabs is supported by several anatomical peculiarities which are present only in king crabs and hermit crabs. Although some doubt still exists about this hypothesis, king crabs are the most widely quoted example of carcinisation among decapods. Several species of king crabs, especially in Alaskan and southern South American waters, are targeted by commercial fisheries and have been subject to overfishing.
Carl Sigismund Kunth was a German botanist. He was also known as Karl Sigismund Kunth or anglicized as Charles Sigismund Kunth. He was one of the early systematic botanists who focused on studying the plants of the Americas. Kunth's notable contributions include the publication of Nova genera et species plantarum quas in peregrinatione ad plagam aequinoctialem orbis novi collegerunt Bonpland et Humboldt. This work spanned seven volumes and was published between 1815 and 1825.
Clethrionomys is a genus of small, slender voles. In recent years the genus name was changed to Myodes, however a 2019 paper found that Myodes was actually a junior synonym for Lemmus, thus making it unusable. As such, Clethrionomys is re-established as the proper genus name. At the same time, several species were moved to the genus Craseomys, so members of both genera are referred to as red-backed voles. This genus was described by Johannes von Nepomuk Franz Xaver Gistel under the pseudonym "G. Tilesius". Some authors cite the taxonomic authority as "Gistel, 1850", whereas others still use "Tilesius, 1850".
Felinae is a subfamily of the Felidae and comprises the small cats having a bony hyoid, because of which they are able to purr but not roar. Other authors have proposed an alternative definition for this subfamily, as comprising only the living conical-toothed cat genera with two tribes, the Felini and Pantherini, and excluding the extinct sabre-toothed Machairodontinae.
Brandt's hedgehog is a species of desert hedgehog native to parts of the Middle East and Central Asia. Its common name derives from its having first been described by Johann Friedrich von Brandt, a director of the Zoological Department at the St Petersburg Academy of Sciences.

Julius Theodor Christian Ratzeburg was a German zoologist, botanist, entomologist, and forester.
Cetotherium is an extinct genus of baleen whales from the family Cetotheriidae.

Pseudonigrita is a genus of sparrow-like birds in the weaverbird family.
Thiaridae, common name thiarids or trumpet snails, is a family of tropical freshwater snails with an operculum, aquatic gastropod mollusks in the superfamily Cerithioidea.
The Munich school is a group of painters who worked in Munich or were trained at the Royal Academy of Fine Arts of Munich between 1850 and 1918. In the second half of the 19th century the Academy became one of the most important institutions in Europe for training artists and attracted students from across Europe and the United States.
