Amblyraja Frerichsi
The thickbody skate (''Amblyraja frerichsi'') is a species of fish in the family Rajidae found off the coasts of Argentina, Chile, and Uruguay. Its natural habitat is open seas. Etymology The skate is named in honor of Thomas Frerichs, the captain of the research vessel ''Walther Herwig Walther Herwig (February 25, 1838, Bad Arolsen, Waldeck – December 16, 1912) was a Prussian administrative lawyer, and the founder of the German fisheries science.

Gerhard Krefft
Gerhard Krefft (30 March 1912 - 20 March 1993) was a German ichthyologist and herpetologist.Stehmann & Hulley (1994). Family His father was a neurologist, who "was an enthusiastic collector of living reptiles and amphibians", and his mother was a concert singer.Stehmann & Hulley (1994), p.558. He and his wife Ingeborg were married in 1947, and they had three daughters.Stehmann & Hulley (1994), p.559. He was the great-nephew of the zoologist, palaeontologist, and Curator of the Australian Museum, Johann Ludwig (Louis) Gerard Krefft (1830–1881). Professional career He had more than 160 scientific publications, many of which were "milestone contributions to the taxonomy and zoogeography Zoogeography is the branch of the science of biogeography that is concerned with geographic distribution (present and past) of animal species. As a multifaceted field of study, zoogeography incorporates methods of molecular biology, genetics, mo ... of oceanic fishes".Stehmann & Hulley (199 ...

Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Walther Herwig
Walther Herwig (February 25, 1838, Bad Arolsen, Waldeck – December 16, 1912) was a Prussian administrative lawyer, and the founder of the German fisheries science. Herwig studied jurisprudence at the University of Göttingen from 1856, where he became a member of the Corps Hannovera. He continued his studies at the universities of Leipzig, Freiburg and Berlin, before entering the Prussian civil service. In 1869 he became district officer for his hometown of Arolsen. He was vice-president of the Provincial Training and Medical College Association in Berlin. From 1879 to 1893 he belonged to the Prussian Lower House. Herwig received his habilitation from the University of Kiel in 1896. He was appointed as a senior government advice in Hanover until his retirement in 1907, when he returned to Berlin. Amongst his other work in the civil service, Herwig promoted the development of a German high seas fishing industry. To this end, in 1880 the first German research vessel was built. ...
