Willy Wolterstorff
Willy Georg Wolterstorff (16 June 1864 in Calbe – 21 January 1943 in Magdeburg) was a German paleontologist and herpetologist. As a child he lost his hearing due to disease, thus finding it necessary to lip-reading, lip-read from an early age. He learned natural sciences through private lessons. After receiving vocational training as a bookbinder, he studied geology from 1884 under Karl von Fritsch (1838-1906) at the University of Halle. At Halle he also received training as a curator. In 1889 he became an assistant to Konrad Oebbeke (1853-1932) at the mineralogical-geological institute at Erlangen, and two years later was appointed curator at the ''Museum für Naturkunde und Vorgeschichte'' (museum of natural history and prehistory) in Magdeburg. After his retirement in 1929, he remained at the Magdeburg museum, performing important functions as a volunteer. Wolterstorff is known for scientific research of "lower vertebrates", in particular investigations involving the syst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calbe
Calbe (official name: ''Calbe (Saale)'') is a town in the district of Salzlandkreis, in Saxony-Anhalt, Germany. Geography It is situated on the river Saale, approx. north of Bernburg, and southeast of Magdeburg. It is known as Calbe an der Saale, to distinguish it from the smaller town of Kalbe on the Milde in the same state. Historically it was a railway junction, and among its industries were wool-weaving and the manufacture of cloth, paper, stoves, sugar and bricks. Cucumbers and onions were cultivated, and soft coal was mined in the neighborhood. The town has a statue of Roland outside its city hall. Roland is a symbol who represents many small and medium-sized towns in Saxony-Anhalt, symbolising free trade and prosperity. The town also has a very old church , and a tower known as the "Hexenturm" ("Witchtower"), in which the townspeople imprisoned accused witches and tortured them in the Middle Ages. The river Saale runs on the east side of the town, and over a weir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salamandridae
Salamandridae is a family of salamanders consisting of true salamanders and newts. Salamandrids are distinguished from other salamanders by the lack of rib or costal grooves along the sides of their bodies and by their rough skin. Their skin is very granular because of the number of poison glands. They also lack nasolabial grooves. Most species of Salamandridae have moveable eyelids but lack lacrimal glands. Nearly all salamandrids produce a potent toxin in their skin, with some species being deadly to many other animal species. With a few exceptions, salamandrids have patterns of bright and contrasting colours, most of these are to warn potential predators of their toxicity. They have four well-developed limbs, with four toes on the fore limbs, and (in most cases) five toes on the hind limbs. They vary from in length. Many species within this family reproduce by method of internal fertilization. Additionally, there are many species-specific courtship rituals that males perform ...

Frogs
A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limbs folded underneath, and no tail (the tail of tailed frogs is an ex ...

Charles Tate Regan
Charles Tate Regan FRS (1 February 1878 – 12 January 1943) was a British ichthyologist, working mainly around the beginning of the 20th century. He did extensive work on fish classification schemes. Born in Sherborne, Dorset, he was educated at Derby School and Queens' College, Cambridge and in 1901 joined the staff of the Natural History Museum, where he became Keeper of Zoology, and later director of the entire museum, in which role he served from 1927 to 1938. Regan was elected Fellow of the Royal Society in 1917. Regan mentored a number of scientists, among them Ethelwynn Trewavas, who continued his work at the British Natural History Museum. Species Among the species he described is the Siamese fighting fish (''Betta splendens''). In turn, a number of fish species have been named ''regani'' in his honour: *A Thorny Catfish '' Anadoras regani'' (Steindachner, 1908) *The Dwarf Cichlid '' Apistogramma regani'' *'' Apogon regani'' *A Catfish '' Astroblepus regani'' * ...

Ernst Ahl
Christoph Gustav Ernst Ahl (1 September 1898 – 14 February 1945) was a German Zoology, zoologist, born in Berlin. He was the director of the department of ichthyology and herpetology in the Museum für Naturkunde. He was also the editor in chief of the review ''Das Aquarium'' from 1927 to 1934. During World War II, Ahl fought in the ranks of the Wehrmacht - in Poland, North Africa and later Yugoslavia. He was executed while in refuge in Yugoslavia, after the partisans found out he was a German. He performed one of the first studies on Pogona, bearded dragons determining what genus they belong to. Ahl is commemorated in the scientific names of two species of lizards: ''Anolis ahli'' and ''Emoia ahli''.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . ("Ahl", p. 3). The latter is a synonym of ''Emoia battersbyi''.

''Austrolebias'' is a genus of killifish in the family Rivulidae.

Killifish
A killifish is any of various oviparous (egg-laying) cyprinodontiform fish (including families Aplocheilidae, Cyprinodontidae, Fundulidae, Profundulidae and Valenciidae). All together, there are 1,270 species of killifish, the biggest family being Rivulidae, containing more than 320 species. As an adaptation to living in ephemeral waters, the eggs of most killifish can survive periods of partial dehydration. Many of the species rely on such a diapause, since the eggs would not survive more than a few weeks if entirely submerged in water. The adults of some species, such as ''Kryptolebias marmoratus'', can additionally survive out of the water for several weeks. Most killies are small fish, from , with the largest species growing to just under . The word ''killifish'' is of uncertain origin, but is likely to have come from the Dutch ''kil'' for a kill (small stream). Although ''killifish'' is sometimes used as an English equivalent to the taxonomical term ''Cyprinodontidae'', s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...
