Ernst Haeckel
Ernst Heinrich Philipp August Haeckel (; ; 16 February 1834 – 9 August 1919) was a German zoologist, natural history, naturalist, eugenics, eugenicist, Philosophy, philosopher, physician, professor, marine biology, marine biologist and artist. He discovered, described and named thousands of new species, mapped a genealogical tree relating all life forms and coined many terms in biology, including ''ecology'', ''phylum'', ''phylogeny'', ontogeny, and ''Protista.'' Haeckel promoted and popularised Charles Darwin's work in Germany and developed the debunked but influential recapitulation theory ("ontogeny recapitulates phylogeny"), wrongly claiming that an individual organism's biological development, or ontogeny, parallels and summarizes its species' evolutionary development, or phylogeny, using incorrectly drawn images of human embryonic development. Whether they were intentionally falsified, or drawn poorly by accident is a matter of debate. The published artwork of Haeckel in ...

Ascandra Densa
''Ascandra densa'' is a species of calcareous sponge The calcareous sponges or calcereans are sponges that make up the class Calcarea, characterized by spicules made of calcium carbonate in the form of high-magnesium calcite or aragonite. While the spicules in most species are triradiate (with three ... from Australia. The species name is derived from a Latin term meaning "dense" or "compact".

Taxa Named By Ernst Haeckel
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later stil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leucaltidae is a family of calcareous sponges in the order Clathrinida Overview The Clathrinida are an order of calcareous sponges found in marine environments.

Ascandra Izuensis
''Ascandra izuensis'' is a species of sea sponge in the family Clathrinidae. The species is named after the Izu peninsula where the holotype was collected. Description ''Ascandra izuensis'' is a calcareous sponge. It is found in the Central Kuroshio Current, Japan Japan is an island country in East Asia. Located in the Pacific Ocean off the northeast coast of the Asia, Asian mainland, it is bordered on the west by the Sea of Japan and extends from the Sea of Okhotsk in the north to the East China Sea .... The sponge consists of loosely branched and anastomosing ascon-tubes directly attached to a substratum. There is no pseudoderm covering the whole colony and no endogastric network. The sponge is rather small and attains a length of about 6 mm. The diameter of the ascon-tubes varies from 0.3 mm to 1 mm and the dermal surface of the tubes have a hispid appearance on account of projecting oxea. The colour of the sponge is yellowish-white when preserved in alc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
