Erich Zugmayer
Erich Johann Georg Zugmayer (16 May 1879, Vienna – 13 February 1938) was an Austrian zoologist and ichthyologist who worked in the Austrian foreign ministry. He collected extensively in Asia where he went on several expeditions including Western Tibet (1906) and Baluchistan (1911). He described several new species of fishes and several bird taxa were described from his collections. Life and work Zugmayer was born in Vienna to Heinrich Zugmayer (1841-1917, director of the metal-making firm of Zugmayer) and his wife Emilie, née Hoffmann (d. 1926). A cousin was the zoologist Hans Hass (1919-2013). He studied liberal arts before studying commerce in London and working in trade and then gave up to study natural sciences at Heidelberg University from 1900. He was influenced by Otto Bütschli, Theodor Curtius, Curt Herbst, Alfred Hettner, Albrecht Kossel, Friedrich Krafft, Robert Lauterborn, Hermann Karl Rosenbusch , Wilhelm Salomon-Calvi and August Schuberg. His doctoral thesis in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slickhead
Slickheads, also known as nakedheads or smoothheads, are deep water fishes that belong to the family Alepocephalidae. They are most commonly found in the bathypelagic layer, which is approximately 3000m below the surface. They get their name from the lack of scales on their heads. Similarly, the scientific name is from the Greek ᾰ̓- (''a''-, "not"); λέπος (''lepos'', "scale"); and κεφαλή (''kephalē'', "head"). It has about 22 genera with ca. 96 species. In Japanese they are known as . Description The following characteristics are generally shared by the Alepocephalidae family: Their mouths consist of 80 to 100 razor-sharp teeth, being rather small and feeble. They are shaped in an eel-like elongation, with large eyes, gill rakers that range from moderate to long and numerous, and spineless fins. The single dorsal fin is located posterior to the midpoint of the body and there is no adipose dorsal fin present, there is a pectoral fin ranging from small to rudimenta ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

Argentiniformes
The Argentiniformes are an order of ray-finned fish whose distinctness was recognized only fairly recently. In former times, they were included in the Osmeriformes (typical smelt and allies) as suborder Argentinoidei. That term refers only to the suborder of marine smelts and barreleyes in the classification used here, with the slickheads and allies being the Alepocephaloidei. These suborders were treated as superfamilies Argentinoidea and Alepocephaloidea, respectively, when the present group was still included in the Osmeriformes. They contain six or seven families with almost 60 genera and at least 228 species. A common name for the group is marine smelts and allies, but this is rather misleading since the "freshwater" smelts of the Osmeridae also live predominantly in the ocean.FishBase (2006)Order Osmeriformes Version of 2006-OCT-09. Retrieved 2009-SEP-28. pp. 190-194 Description and ecology The Argentiniformes are smallish silvery or dark and generally bathypelagic oc ...

Actinopterygii
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinopt ...
