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 Symmetry in biology#Bilateral symmetry, bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and th ...

Arachnoides
''Arachnoides'' is a genus of sea urchin within the family Clypeasteridae, found in the Indo-Pacific oceans. The base is flat and the upper surface is convex. If you are looking for a ''fern'' genus, its name is Arachniodes. Species The World Register of Marine Species list the following species as being in this genus:- * ''Arachnoides placenta'' ( Linnaeus, 1758) Australia to Philippines * ''Arachnoides tenuis'' H. L.

Nathanael Gottfried Leske
Nathanael Gottfried Leske (22 October 1751 in Muskau – 25 November 1786 in Marburg) was a German natural scientist and geologist. After his studies at ''Bergakademie'' of Freiberg in Saxony and the ''Franckeschen Stiftungen'' in Halle, Leske became a special professor of natural history at the University of Leipzig in 1775. From 1777 to 1786 he taught economics at this university, and in 1786 he was called to the chair of financial science and economics at the University of Marburg. However, he had a fatal accident on his way to Marburg. Throughout his life Leske corresponded with his teacher and close friend of Abraham Gottlob Werner, famous geologist and mineralogist at Weimar. He also edited the ''Leipziger Magazin zur Naturkunde, Mathematik und Oekonomie'' (1781-1789) with [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Echinodermata
An echinoderm () is any member of the phylum Echinodermata (). The adults are recognisable by their (usually five-point) radial symmetry, and include starfish, brittle stars, sea urchins, sand dollars, and sea cucumbers, as well as the sea lilies or "stone lilies". Adult echinoderms are found on the sea bed at every ocean depth, from the intertidal zone to the abyssal zone. The phylum contains about 7,000 living species, making it the second-largest grouping of deuterostomes, after the chordates. Echinoderms are the largest entirely marine phylum. The first definitive echinoderms appeared near the start of the Cambrian. The echinoderms are important both ecologically and geologically. Ecologically, there are few other groupings so abundant in the biotic desert of the deep sea, as well as shallower oceans. Most echinoderms are able to reproduce asexually and regenerate tissue, organs, and limbs; in some cases, they can undergo complete regeneration from a single limb. Geol ...

Order (biology)
Order ( la, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
