Oreasteridae
The Oreasteridae are a family of sea stars in the class Asteroidea. Description and characteristics This family contains many species of regular starfishes with usually 5 arms around a stiff, convex and often brightly colored body. Whereas some species are very easy to identify, like the "pincushion seastars" ('' Culcita sp.''), some other can be difficult to tell apart.

Ludwig Heinrich Philipp Döderlein
Ludwig Heinrich Philipp Döderlein (3 March 1855, Bad Bergzabern – 23 April 1936, Munich) was a German zoologist. He specialized in echinoderms, particularly sea stars, sea urchins, and crinoids. He was one of the first European zoologists to have the opportunity to do research work in Japan from 1879 to 1881. Today, he is considered one of the most important pioneers of marine biological research in Japan. He was the director and curator of the Musée zoologique de la ville de Strasbourg from 1882 to 1919. He headed the Zoologische Staatssammlung München from 1923 to 1927 and was Professor of Zoology in the Ludwig Maximilian University of Munich. Biography Ludwig Döderlein was born in Bad Bergzabern, then Kingdom of Bavaria, on March 3, 1855. He went to school in Bayreuth from 1864 to 1873. From 1873 to 1875 he studied natural sciences in the University of Erlangen, where he also worked as an assistant to the Zoologist Emil Selenka in the summer of 1875. From 1875 to 1876 ...

Karl Möbius
Karl August Möbius (7 February 1825 in Eilenburg – 26 April 1908 in Berlin) was a German zoologist who was a pioneer in the field of ecology and a former director of the Museum für Naturkunde in Berlin. Early life Möbius was born in Eilenburg in Saxony. At the age of four he attended primary school at the Bergschule Eilenburg, and at the age of 12 he was sent by his father to train as a teacher. In 1844 he passed the exams with distinction and began working as teacher in Seesen, on the northwest edge of the Harz mountain range. In 1849, and encouraged by Alexander von Humboldt, he began studying natural science and philosophy at Natural History Museum of Berlin. After he graduated, he taught from 1853 to 1868 zoology, botany, mineralogy, geography, physics, and chemistry at the Gelehrtenschule des Johanneums in Hamburg. Oysters and ecology In 1863 he opened the first German sea water aquarium, in Hamburg. In 1868, shortly after passing his doctoral examination at the ...

Sea Star
Starfish or sea stars are Star polygon, star-shaped echinoderms belonging to the class (biology), class Asteroidea (). Common usage frequently finds these names being also applied to brittle star, ophiuroids, which are correctly referred to as brittle stars or basket stars. Starfish are also known as asteroids due to being in the class Asteroidea. About 1,900 species of starfish live on the seabed in all the world's oceans, from warm, tropics, tropical zones to frigid, polar regions of Earth, polar regions. They are found from the intertidal zone down to abyssal zone, abyssal depths, at below the surface. Starfish are marine invertebrates. They typically have a central disc and usually five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates. Many species are brightly coloured in various shades of red or orange, while others are blue, grey or brown. Starfish have tube fee ...

Monotypic Echinoderm Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus (biology), genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the Order (biology), order Amborellales, there is only one family (biology), family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is ...
